Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music apparatus having a function of allowing a user to hear a sound to be sounded and answering the same sound by key operation.

[0002]

2. Description of the Related Art Conventionally, a user is made to listen to a single note randomly given out of some prepared single note sounds, and the same sound is answered by operating an electronic musical instrument. There was a music device with a game function.

[0003] Such a device determines whether a user's answer is right or wrong and informs the result of the determination by voice or the like. When the user plays it as a game machine, he or she can learn the sense of sound, especially instrumental music or vocal music. It has the advantage that the important "sound hearing" ability naturally improves.

[0004]

However, as the user's "hearing" ability improves, the fun as a game becomes monotonous with only a single tone, and in the end,
There was a problem that the interest in games became weak.

An object of the present invention is to make it possible to enjoy a game of problems / answers not only for single notes but also for chords,
It is to be able to naturally improve the learning ability of "listening sounds".

[0006]

The first aspect of the present invention is as follows.
It has the following configuration. First, there is a problem sound questioning means for randomly selecting an arbitrary problem sound out of the problem sounds composed of a plurality of kinds of chords prepared in advance and pronouncing it.

Next, there is provided a key input means for allowing the user to input each key of the answer sound composed of the constituent sounds of the chord corresponding to the problem sound. The same means causes the user to input each key of the answer sound composed of the constituent sounds of the chord corresponding to the problem sound, simultaneously or in order.

Further, the problem sound produced by the problem sound questioning means and the answer sound of each key inputted by the user by the key input means are compared with each other to judge whether the answering operation by the user is right or wrong, and the judgment result is responded to the user. It has a correctness determination means.

The second aspect of the present invention has the following configuration. First, it has a question sound questioning means, a key input means, and a correctness determination means similar to the case of the first aspect.

Further, there is provided a reference-tone-tone producing means for sequentially producing reference tones at timings other than the answering operation by the user. The third aspect of the present invention has the following configuration.

First, it has a question sound questioning means and a key input means similar to the case of the first mode. Next, there is a waiting time measuring means for measuring a waiting time after the problem sound questioning means produces the problem sound until the user inputs all the keys of the answer sound corresponding to the problem sound by the key input means.

Further, it has the same function as the case of the first aspect, and if the waiting time measured by the waiting time measuring means exceeds a predetermined time limit, the answer operation by the user is determined as an incorrect answer. It has a judging means.

The fourth aspect of the present invention has the following configuration. First, it has the same key input means and correctness determination means as in the case of the first aspect. Next, among the problem sounds consisting of a plurality of sets of chords each having different difficulty levels, each of which is prepared in advance, a random problem sound in a set of a predetermined difficulty level is randomly selected and pronounced. It has a problem sound questioning means.

Further, based on the frequency at which the correctness determination means determines that the answering operation by the user is the correct answer, the difficulty level selection for controlling the set of problem sounds consisting of chord constituent sounds of different difficulty levels selected by the problem sound questioning means. It has a control means. For example, when the correctness determination means determines that the answer operation by the user is a correct answer more than a predetermined number of times in succession, the problem sound questioning means determines a problem sound composed of chord constituent sounds having a higher degree of difficulty than the previous question. Select a pair.

[0015]

According to the first aspect of the present invention, it is possible to enjoy a question / answer game for chords.

According to the second aspect of the present invention, when the user performs the answering operation for the problem sound, for example, before the operation, the reference scale sound producing means sequentially produces the reference scale notes. As a result, the user can learn the reference sound for the problem sound in advance, and can efficiently improve the learning ability of “listening sound”.

According to the third aspect of the present invention, when the user performs the answering operation for the problem sound, if the user does not input all the keys of the answering sound for a predetermined time limit or longer, the correctness determining means determines the waiting time measuring means. The answer operation by the user is determined to be an incorrect answer based on the measurement result in. As a result, the question sound can be advanced.

According to the fourth aspect of the present invention, for example, when the frequency of correct answers by the user increases, the difficulty level selection control means causes the problem sound questioning means to include a problem sound composed of chord constituent sounds of high difficulty. Control to select a set of. As a result, the ability of the user to "listen" can be gradually improved.

[0019]

Embodiments of the present invention will now be described in detail with reference to the drawings. Overall Configuration FIG. 1 is an overall configuration diagram of an embodiment of the present invention.

In FIG. 1, a CPU (Central Processing Unit) 101, in accordance with a program written in a program memory 102, stores a key code of a key (single-tone key code or chord) for a question stored in a data memory 107, which is a ROM. Set of key codes) and questions based on data such as rhythm patterns.

For a musical tone such as a single tone, a chord, or a rhythm at the time of a question, the CPU 101 reads a musical tone signal from the musical tone memory 105, converts it into an analog signal by the D / A converter (DAC) 108, and outputs it from the sound system 109. It is pronounced by being emitted.

For the voice message for the question and the user's answer, the CPU 101 uses the human voice memory 1
The human voice sound signal stored in the ADPCM system in 06 is read out, converted into an analog signal by the D / A converter (DAC) 108, and emitted from the sound system 109 to be uttered.

The mode switch 104 has a structure as shown in FIG. 2, and in addition to the POWER OFF position for powering off by a lever, the PLAY mode position for performing a normal keyboard performance, particularly in the present invention. GA related to practice single notes, chords, or rhythms
The ME mode position is selected.

The embodiment of the present invention having the above configuration is characterized by the operation in the GAME mode selected by the mode switch 104. The operation of the GAME mode will be described below with respect to the first to third embodiments. First Embodiment of GAME Mode First, a first embodiment of the GAME mode will be described. <Outline of Operation of First Example> In the first example of the GAME mode, the user can enjoy a game in which a pitch of a single note, which is a kind of pitch game, is applied. In this case, the user answers by listening to a single note that is pronounced as a problem from the electronic keyboard instrument and pressing a note with the same pitch.

Next, the outline of the game will be described with reference to the conceptual diagram of FIG. First, after various initial settings are made (step S301), the user selects the mode switch 10
When 4 is set to the GAME mode (see FIG. 2), the electronic musical instrument continues to utter a message saying "This sound, what?" (Step S302), and each musical scale as a pitch reference, for example, C major scale. De, le, mi, fa, so, la, shi, de (keyboard C ₄ , D ₄ , E ₄ , F ₄ ,
The musical tones that are the respective scale tones that compose G ₄ , A ₄ , B ₄ , and C ₅ are sounded (step S303). By listening to each of these scale tones, the user can obtain a relative pitch when answering each musical tone to be presented (hereinafter referred to as “problem sound”).

Next, from the electronic musical instrument, one problem sound (musical sound) having a pitch determined by a random number and to be answered by the user is created, and the question, that is, the pronunciation is produced (step S304, S305).

After that, the electronic musical instrument enters a key-depression waiting state,
The user listens to the above-mentioned problem sound and, within 20 seconds, depresses the key determined to have a pitch equal to that of the single sound (step S306).

As a result, if the pitch of the single note heard by the user matches the pitch of the key pressed, the end message of the voice "Seikai" is pronounced, and then the same pitch as the correct answer, A voice with a name, for example, the content of "dough" is pronounced. After that, a message with the voice "next mondai" is pronounced (step S308), and a new single-tone question is repeated as in the previous time.

As a result, if consecutive correct answers are obtained, the number of consecutive correct answers is counted up (step S310). In this way, when the number of consecutive correct answers exceeds the specified value, the range of single-note questions is expanded. For example, until now, the range I corresponding to only the white key on the keyboard was changed to the white key and the black key. Questions will be asked from the range II including the key (step S31).
2).

If the pitch of the single note heard by the user and the key pressed by the user are incorrect, "Zan-nen, again and again"
Even if there are consecutive correct answers, the number of consecutive correct answers is cleared (step S313).

After that, the same wrong question is posed again (step S305), and the game is continued as before. A specific operation of the first embodiment based on the above outline will be described with reference to operation flowcharts of FIGS. 4 to 9 and FIGS. 11 to 16 and an explanatory view of FIG. 10.

In the operation according to each of the above operation flow charts, in FIG. 1, after the control (1) stored in the program memory 102 by the CPU 101, a message "voice of next" is sounded (step S30).
8), a new single note is repeated as in the previous time.

As a result, if consecutive correct answers are obtained, the number of consecutive correct answers is counted up (step S310). In this way, when the number of consecutive correct answers exceeds the specified value, the range of single-note questions is expanded. For example, until now, the range I corresponding to only the white key on the keyboard was changed to the white key and the black key. Questions will be asked from the range II including the key (step S31).
2).

If the pitch of the single note heard by the user and the pitch of the depressed key are wrong, the keyboard 103 and the mode switch 104 (see FIG. 2) in FIG. 1 are scanned, and their states are read by the CPU 101. Is taken into (step S
402).

The mode switch 104 (see FIG. 2) is set to G
POWED from either AME position or PLAY position
When switched to the R OFF position, POWER OFF processing for powering off is executed (step S
403).

Further, the mode switch 104 is set to POW
When the GAME position is switched from either the R OFF position or the PLAY mode position, the GAME MODE I performs initial settings at the start of the game mode.
N processing (step S404) is executed.

The GAME MODE IN process is shown in FIG. In FIG. 5, first, each register is initialized (step S501). Next, the content of the variable MODE indicating the mode is set to GAME MODE (step S502). The contents of this flag are described in step S407 of FIG. 4 or step S601 of FIG. 6 described later.
It is judged by etc.

Subsequently, the during-GAME MODE IN flag is turned on (step S503). The content of this flag is determined in step S602 of FIG. 6 described later.

Next, the content of the variable indicating the question range is set to the range I. This range I corresponds only to the white keys on the keyboard 103 of FIG. 1 (step S504). Next, the content of the variable indicating the number of consecutive correct answers is initialized to 0 (step S505).

Thereafter, as a message (MODE IN MES.) At the start of the game mode, the human voice memory 10
From 6, the audio data by the ADPCM system having the content "This sound what?" Is read (step S50).
6), the attack process causes the message to be sounded (step S507). Attack processing is C in FIG.
The PU 101 uses the musical tone message 105 or the human voice memory 106 to generate musical tone data or ADP based on the PCM method.
This is a process of reading the audio data in the CM system and sequentially outputting it to the D / A converter 108.

Step S4 of FIG. 4 shown in the above operation
For the 04 GAME MODE IN process, the mode switch 104 (see FIG. 2) moves from the GAME position to the PL position.
When switched to the AY position, the GAME MODE release process (step S405) for ending the game mode is executed, and then the normal PLAY process (step S406) for playing the electronic musical instrument is executed.

The operation when the game mode is selected by setting the mode switch 104 to the GAME position will be described below. First, the variable MO indicating the current mode
It is determined whether the DE content is GAME MODE (step S407). Since it is currently in the game mode, this determination is YES (see S502 in FIG. 5).

At the next step S408, the keyboard 103
Is determined whether or not the key can be depressed (keyboard ON). Normally, the keyboard remains ON in S401 of FIG. 4, so this determination is YES.

In the following step S409, the step S
As a result of the switch scanning of 402, it is determined whether or not a new key depression has occurred. At the start of the game mode, the user has not pressed any keys yet, so this determination is NO.

As a result, the keyboard processing of step S411 is executed. Here, note-on information at the time of key depression, information on the pitch and velocity of the depressed key, key information at the time of key release, etc. are fetched in a register or the like in the CPU 101. At the start of the game mode, since the user has not pressed or released the keys, virtually no processing is executed.

Next, the AN in step S412 described later.
After the SER time process, the flow loop timer process of S413 is executed. Here, the time required for one round of the processing of the main flow of FIG. 4 (repetition of S402 to S415) is measured. The time information obtained as a result is used for timing control for producing a rhythm sound or the like.

Subsequently, the one-round flow sound generation processing of step S414 is executed. Here, the processing of actually producing or muting a musical sound is executed based on the processing result of the keyboard processing of step S411.

Further, the one-cycle initial process of the flow of step S415 is executed. Here, for example, various initialization processes are performed, such as clearing the contents of the register indicating the state of the key that is "new key depression state" as a result of the switch scanning in step S402. <Explanation of Operation at Start of Game Mode in Specific Operation of First Embodiment> Next, ANSWE in step S412
The R time processing will be described with reference to FIG.

In FIG. 6, first, it is determined whether the content of the variable MODE indicating the current mode is GAMEMODE (step S601). Since it is currently in the game mode, this determination is YES (see S502 in FIG. 5).

At the next step S602, GAME
It is checked whether or not the MODE IN flag is ON. At the start of the game mode, this flag is set to step 4 in FIG.
Since it is turned on in step S503 of FIG. 5 in the 04 GAME MODE IN processing, the determination in step S602 is YES, and the MOD of the next step S603.
The E IN progress process is executed. This process is shown in FIG.

In FIG. 8, first, it is determined whether or not the message (MODE IN MES.) At the start of the game mode is being sounded (step S801). This message is a GAME MODEIN in step 404 of FIG.
This is a message with the voice "This sound, what?" That is sounded by the processing of steps S506 and S507 of FIG. 5 in the processing.

If this message is sounding at the start of the game mode, the MODE IN progress process of FIG. 8 is immediately terminated, and the process returns to the main flow of FIG. 4 via the ANSWER time process of FIG. The process of step S412 ends. Then, the main flow of FIG. 4 makes one round, and the determination of step S801 of the MODE IN progress process of FIG. 8 is repeated again.

Then, the above message (MODE IN
MES. ), The determination in step S801 is NO, and the process proceeds to steps S802 and S803. As described above in step S303 of FIG. 3, when the game mode is started, the message (MOD
E IN MES. ), To facilitate the user's answer, each scale that serves as a reference of the pitch, such as C, D, L, M, H, F, S, L, S, D (keyboard C4, D
4, E4, F4, G4, A4, B4, C5)
Each of the scale notes that make up is sequentially pronounced.

Therefore, first, in step S802, it is determined whether or not a musical tone is being sounded (step S).
802). At the beginning, the message (MODE I
N MES. ), The musical tones have not yet been pronounced, so steps S802 and S80 are performed.
With No. 3, the determination is NO, and the process proceeds to step S807.

At step S807, the variable release counter RL_CNT is cleared (step S8).
07). As will be described later, this counter is a time counter for producing each scale tone for 0.5 seconds,
After the above clearing, this content is counted up by a timer (not shown) in the CPU 101 (FIG. 1).

In the following step S808, the key code of each musical tone (corresponding to the first musical scale "do" in this case) is acquired and set in the tone key memory (step S8).
08). It is assumed that the key code of each scale tone is programmed in advance.

Then, from the tone memory 105 of FIG. 1, a PC having the key code set in the above-mentioned tone key memory
The musical tone data of the musical tones according to the M method are read out, and the musical tones are produced by the attack processing (step S809).

Next, after the ANSWER time process of FIG. 6 and the main flow (S412) of FIG. 4, the process returns to step S802. Then, it is determined whether or not a musical tone (in this case, a musical tone corresponding to the musical scale “do”) is being sounded.

As a result, if the musical tone is being sounded, it is judged whether or not it is being released (step S803).
If it is being released, the determination is YES, and the ANS in FIG.
After processing the WER time, return to the main flow of FIG.
The process of step S412 ends.

If the release is not in progress, step S803.
Is NO, and in the next step S804, it is determined whether or not the value of the release counter RL_CNT that has been incremented after being cleared in S807 at the same time as the attack is equal to or greater than the count value corresponding to 0.5 seconds. To be done.

While this judgment is NO, the ANS of FIG.
After the WER time process, the process returns to the main flow (S412) in FIG. 4, and the pronunciation of the musical tone currently being sounded is continued. When the determination in step S804 is YES during the repetition of the main flow, the release process of the next step S805 starts the attenuation process of the envelope of the musical tone currently being sounded, and returns to the main flow of FIG. After that, every time the MODE IN progress process of FIG. 8 is executed, the determination in step S803 becomes YES, and the musical tone currently being sounded is muted.

In this way, when the first musical tone is released and the envelope value becomes 0, step S
The determination of 802 is NO, and the next step S806
Then, it is determined whether or not the pronunciation of the musical tones has been completed (step S806).

If all the pronunciations of the musical tones have not ended, the release counter RL_CNT is cleared again for the next musical tone in step S807, and the key number of the next musical tone is acquired in step S808.
Sound generation (attack) processing is performed in step S809.

By repeating the above-described processing, the pronunciation of all the musical tones corresponding to the scales "do, re, mi, fa, so, la, shi, do" is completed for about 0.5 seconds each. If so, the process proceeds from step S806 to step S810, and the MODE IN in-progress flag is cleared (step S810). <Explanation of Question Sound Questioning Operation in Specific Operation of First Example> Thereafter, ANSE in step S412 of FIG.
When the R time process is executed, the determination in step S602 of FIG. 6 becomes NO, and the process proceeds to the question progress process of step S604. This process is shown in FIG.

Regarding the progress of the questions, 4 shown in FIG.
The two states are repeated. That is, "standby state" →
"Asking" → "Waiting for input" → "Displaying message" 4
In one of the four states, for example, a 2-bit current sequence flag represents one of the four states.

This current sequence flag is initialized to a value indicating the "standby state" in step S501 of FIG. 5 in the GAME MODE IN processing of step 404 of FIG. 4 described above. The "standby state" is a state in which questions have not been given yet.

As described above, since the initial state is the "standby state" and the determination in step S901 in FIG. 9 is NO, the questioning progress process in FIG. 9 is immediately ended, and the END MESSAGE progress process in step S605 in FIG. 6 is completed. Is executed.

This END MESSAGE progress processing is shown in FIG. 11, but if the sequence flag is currently the value indicating "displaying message" described above, step S
When 1101 is YES, the processes from step S1102 are executed. Therefore, at the beginning, step S1101
Is NO, the END MESSA of FIG.
Immediately terminate the GE progress processing, and then step S60 in FIG.
Proceed to 6.

Further, as described above, since the current sequence flag initially has a value indicating the "standby state", the determinations at steps S606, S607 and S608 are all NO, and the process proceeds to step S609.

In step S609, it is determined whether the correctness flag is "correct" (step S609). This right / wrong flag indicates that the GAME MO in step 404 of FIG.
Since it is initialized to "positive" in step S501 of FIG. 5 in the DE IN process, the determination in step S609 is YE.
It becomes S.

In subsequent step S610, random number processing is executed. This random number process is a process of determining the pitch of the problem sound, that is, the key code by a random number, and is shown in FIG.

First, a predetermined random number memory value is read (step S1501). This memory value is
At the timing when 1501 is executed, it is calculated and held by a random number generation process (not shown).

Next, it is determined whether or not the content of the variable indicating the question range is the range I (step S1502). First, the GAME MODE IN of step 404 in FIG.
Since the range I has been initialized in step S504 of FIG. 5 in the process, step S1503 is executed.

In step S1503, step S15
The remainder obtained by dividing the random number memory value read in 01 by the number of range I is stored in the question key memory (step S150).
3). Here, the number of ranges I is equal to the total number of white keys on the keyboard 103 of FIG. 1, and the above-mentioned remainder value is nothing but a key code indicating one of the white keys. That is, this remainder value is stored in the question key memory as the key code of the musical tone (question key) to be questioned.

As the above processing, step S610 in FIG.
After the random number process of is executed, the questioning process of step S611 of FIG. 6 is executed. This process is shown in FIG.

First, the key code stored in the question key memory is set in the pronunciation key memory (step S160).
1). Then, the tone data of the question key by the PCM system having the key code set in the tone key memory is read out, and is sounded by the attack process (step S1602).

At the next step S1603, the current sequence flag is changed to a value indicating "in question" (step S1603). In addition, the counter S_CN which is a variable
T is cleared (step S1604), and the flag S_CNT_FLG is also cleared (step S1).
605). These two will be described later.

Next, the release counter RL_CNT is cleared (step S1606). This counter is a time counter for causing the musical tone to be presented for 0.5 seconds at a time, as in the case of the above-mentioned scale tone, and after the clearing, this content is a timer (not shown) in the CPU 101 (FIG. 1). Is counted up by.

Thereafter, the keyboard 103 of FIG. 1 is set to the key-disabled state (keyboard OFF) in order to prevent the user from accepting the key-pressing operation during the questioning (step S).
1607).

By the above processing, step S61 in FIG.
The questioning process of No. 1 is ended, the process returns to the main flow of FIG. 4, and the ANSWER time process of step S412 is ended. Since the keyboard 103 of FIG. 1 is in the key-depressable state as described above, the determination in step S408 is NO,
The process returns again to the ANSWER time process of step S412.

Then, in the question progress process (FIG. 9) in the step S604 of the ANSWER time process of FIG. 6, the current sequence flag is set to the value indicating "in question" as described above (step S1603 of FIG. 16). ), The determination in step S901 is YES, and since the musical tone having the key code of the question key is being sounded at first, the determination in step S902 is also YES.

Further, since the release is not in progress at the beginning, the determination in step S903 is NO, and in step S904, the release counter R, which has been incremented at the same time as the attack, has been cleared in S1606 in FIG.
It is determined whether or not the value of L_CNT is equal to or greater than the count value corresponding to 0.5 seconds.

While this judgment is NO, ANS in FIG.
After the WER time process, the process returns to the main flow (S412) in FIG. 4, and the tone generation of the musical tone of the question key currently being generated is continued. Step S904 in the repetition of the main flow
If the judgment is YES, the release process of the next step S905 starts the process of attenuating the envelope of the musical tone of the question key currently being sounded, and returns to the main flow of FIG. After that, every time the question progress process of FIG. 9 is executed, the determination in step S903 becomes YES, and the musical sound of the question key currently being sounded is muted. <Explanation of Answering Operation of User in Specific Operation of First Example> In this way, when the musical tone of the question key is released and the envelope value becomes 0, step S902.
Is NO, the process moves to step S906. Here, the value of the current sequence flag is updated from "in question" to a value indicating "waiting for input" (waiting for ANS).

Further, in the next step S907, FIG.
The keyboard 103 is set to the key-depressible state (keyboard ON). Further, in step S908, the variable ANS
The wait counter is cleared. As will be described later, this counter is set to 2 when the user presses a key serving as an answer.
A counter for counting the 0 second time limit,
After the above clearing, this content is counted up by a timer (not shown) in the CPU 101 (FIG. 1).

As the above processing, step S604 in FIG.
After the question progress process is finished and the determination in step S1101 in FIG. 11 in step S605 in FIG. 6 is NO,
The determinations in steps S606 and S607 in FIG. 6 are NO, and the determination in step S608 is YES, resulting in step S61.
Go to 2.

In step S612, step S604
The value of the ANS standby counter that has been incremented after being cleared in S908 of FIG.
It is determined whether or not the count value is equal to or greater than 0 seconds. That is, it is determined whether the waiting time until the user presses the key for the answer after the pronunciation of the musical tone of the question key has exceeded 20 seconds.

If the value of the ANS standby counter is not equal to or greater than the count value corresponding to 20 seconds, step S61.
Proceed to 6. Steps S616, S617 and S618
The counter S_CNT, which is a variable, will be described later.
Since the content of is still cleared in step S1604 of FIG. 16 of the questioning process of step S611, the determination in step S616 is initially NO. As a result, the process returns to the main flow of FIG. 4, and the ANSWER time process of step S412 ends. Then, the determination in step S408 is Y
If the user does not press the key for answering after ES, the determination in step S409 becomes NO, and the process returns to the ANSWER time process in step S412. Then, the determination in step S601 is YES, and step S60
The determination in step 2 is NO and the question passing process in step S604 is executed, but the determination in step S901 in FIG. 9 is N.
This process ends as soon as it reaches O. Further, step S6
The END MESSAGE progress process of 05 is executed, but the determination in step S1101 of FIG. 11 becomes NO, and this process also ends immediately. Then, step S60
6, after the determination in S607 is NO and the determination in step S608 is YES, the waiting time until the user presses the key for the answer after the pronunciation of the musical tone of the question key is not longer than 20 seconds If the determination in step S612 is NO, the process proceeds to step S616, and as described above, this determination is also NO.

As the loop processing, the "input waiting" state (ANS standby state) of FIG. 10 is continued. When the waiting time until the user presses the key exceeds 20 seconds in the "input waiting" state by the above loop processing, the determination in step S612 becomes YES. As a result, the correctness / incorrectness flag is set to “erroneous” (step S613), the number of consecutive correct answers is reset to 0 (step S614), and step S
At 615, the END_MES process described in detail below is executed. Then, in this processing, a message with a voice of "Zan-n-n-n, Ichi-n-done" is transmitted.

When the user presses the key for the answer within 20 seconds after starting the pronunciation of the musical tone of the question key in the "input waiting" state by the above loop processing, step S4 in FIG.
The determination result in 09 is YES, and the ANS in step S410
WER TRIGGER processing is executed. This process is shown in FIG.

First, it is determined whether the flag S_CNT_FLG is 1 (step S701). This judgment is NO
If so, the flag S_CNT_FLG is set to 1 (step S702), and if the determination is YES, the next step S70.
Go to 3. Normally, the flag S_CNT_FLG is set to the step S16 in FIG. 16 in the question processing in step S611 in FIG. 6 in the ANSWER time processing in step S412 in FIG.
Since it is still cleared in 05, the above determination is NO. The case in which this determination is YES will be described later. When the flag S_CNT_FLG is set to 1, the cleared counter S_CNT starts counting up.

In step S703, the key code of the depressed input key is stored in the memory. As the above processing, the ANSWERTRIG of step S410 in FIG.
When the GER process is executed, a process for determining whether or not the answer by the user's key depression is correct (ANSWE described later).
R processing) should be performed. However, step S6 in the ANSWER time process of step S412 of FIG.
The determination of 16 is still NO until the value of the counter S_CNT, which has started counting up as described above, exceeds the value corresponding to 1 second, so the loop processing in the “input waiting” state described above is repeated. Be done. This is for the following reasons.

Now, when a single tone for the question is pronounced and the user depresses a certain key as the answer, the musical tone corresponding to the depressed key may or may not be the correct answer, and the step S in FIG.
It is sounded by an attack process (not shown) in the keyboard process of 411. Then, if no measures are taken, it is immediately determined whether or not the user's answer is correct,
A message is pronounced based on the result of the determination. Here, when the message is pronounced, all the musical tones currently being pronounced are rapidly muted in order to clarify the pronunciation (see step S1401 in FIG. 14, which will be described later). Then, the processing from when the user presses the answer key until the message is sounded is executed in a very short time as digital processing. Therefore, the mute processing for producing the message is performed depending on whether or not the musical tone of the key pressed by the user is pronounced, and as a result, the musical tone of the key pressed by the user cannot be heard at all or hardly. Become.

In order to prevent such a situation and allow the user's key depression sound to be clearly pronounced, the ANSWE of step S619 in FIG. 6 for determining the correct answer.
A waiting time of about 1 second is provided before the R process is executed. This idling is performed by the determination process in step S616 of FIG. 6 regarding the counter S_CNT.

If the user presses the key for answering again within one second, if the user presses the key again, step S4.
The ANSWER TRIGGER processing of 10 is executed again and a new input key is used as the answer. In this case, since the flag S_CNT_FLG has already been set to 1, step S701 becomes YES and the processing of step S702 is executed. Not done. <Explanation of Correct Answer / Incorrect Answer Processing in Concrete Operation of First Embodiment> After the idling for 1 second described above, the counter S_
When the value of CNT exceeds the value corresponding to 1 second, step S
The determination of 616 is YES. Then, step S61
The counter S_CNT is cleared in step 7, and step S61
After the flag S_CNT_FLG is cleared in 8, the ANSWER process of step S619 for determining the correct answer is executed. The ANSWER process is shown in FIG.

First, the question key stored in the question key memory in step S1503 in FIG. 15 in the random number process in FIG. 6 in the ANSWER time process in FIG. 4 is acquired (step S13).
01), and ANSWER in step S410 of FIG.
The key code of the input key stored in the memory in step S703 of FIG. 7 in the TRIGGER process is acquired (step S1302).

Then, it is determined whether or not the key codes of the input key and the question key match (step S130).
3). If they match, the correctness / incorrectness flag is set to “correct” (step S1304), and the content of the variable indicating the number of continuous correct answers is +.
The count is incremented by 1 (step S1305). Next, it is determined whether or not the content of the variable indicating the number of consecutive correct answers exceeds the predetermined number N (step S1306). If this determination is NO, END_MES processing (step S131
Go to 0). If the determination in step S1306 is yes,
The content of the variable that shows the question range is from range I to range I
After being changed to I (step S1307), END_M
The process proceeds to ES processing (step S1310). Step S1
The meaning of 307 will be described later.

If the input key does not match the question key and the determination in step S1303 is NO, the correctness / incorrectness flag is set to "incorrect" (step S1308), and the number of consecutive correct answers is cleared (step S1309). ), END_MES
The process (step S1310) is executed.

The END_MES processing of step S1310 is shown in FIG. In order to clearly pronounce the correct or incorrect message, all-tone high-release processing is executed in which all the musical tones currently being sounded are rapidly muted (step S1401). Then, after it is confirmed that the envelope values of all the musical tones have become 0 (step S1402), the process proceeds to step S1403.

In step S1403, the keyboard 103 of FIG. 1 is in the key-disabled state (keyboard O in order to prevent the key-pressing operation by the user from being accepted while the message is being sounded).
FF).

Next, if the correctness / incorrectness flag is "correct", the determination in step S1404 becomes YES, and the voice data of the correct answer message according to the ADPCM method of "content" is read from the human voice memory 106 in FIG. Then, the message is sounded by the attack process (step S1405) (step S1407).

If the correctness flag is "wrong", step S1
The determination of 404 is NO, and the ADPC of the content "Zan-n-n-n-n-n-n-n-n" is read from the human voice memory 106 in FIG.
The voice data of the correct answer message according to the M method is read (step S1406), and the message is sounded by the attack process (step S1407).

Thereafter, the sequence flag is changed to a value indicating "currently displaying message" (step S140).
8). After the above step S1408, the END_MES process of step S1310 of FIG.
And ends the ANSWER process.

Then, returning to FIG. 4 of the main flow, after finishing the ANSWER time process of step S412, the process proceeds to steps S402 → S407 → S408, and further, since the keyboard is currently off, step S4
After the determination in step 408 is NO, step S41 is performed again.
2 ANSWER time processing is executed.

In the ANSWER time process, steps S601 → S602 → S604 of FIG. 6 (S90 of FIG. 9).
The judgment of 1 is NO) → S605, END MESS
AGE progress processing is executed. This process is shown in FIG.

First, in step S1101, it is determined whether or not the sequence flag is currently "displaying a message", and the end message (END_ME
It is determined whether or not (S) is sounding. This message is
The message is a voice message "Seikai" or "Zan-nen, Ichido-do" read in step S1405 or S1406 of FIG. 14 and pronounced in step S1407.

The end message is sounding and step S1
If the determination in step 101 is YES, the next step S11
In 02, it is determined whether or not the correct answer is being sounded. If the correct message is read in step S1405 of FIG. 14, the correct answer is being pronounced, and if the incorrect message is read in step S1406, the correct answer is not being pronounced.

If the correct answer is currently being sounded, step S11.
The correct answer MES progress process of 05 is executed. This process is
It is shown in FIG. First, in step S1201,
It is determined whether or not the correct answer message "Seikai" is being sounded.

While "seikai" is being sounded, it is determined in the next step S1202 whether or not there is silence. This determination is NO while the message "SEIKAI" is not silent, and the correct answer MES in step S1105 in FIG.
After the progress processing is completed, END in step S605 of FIG.
The MESSAGE elapsed process is terminated, the determination in step S606 is NO, the determination in step S607 is YES, the ANSWER time process in step S412 of FIG. 4 is terminated, and the process returns to the main flow. Then, again in step S of FIG.
412 is executed, and steps S601 to S602 in FIG.
→ S604 (NO in step S901 of FIG. 9) →
S605 → S1101 → S1102 → S110 in FIG.
5 → step S120 along the route of S1201 in FIG.
Come back to 2.

By repeating the above-mentioned loop processing, the pronunciation of the message "SEIKAI" continues.
When this message becomes silent, step S1
The determination in 202 is YES, and step 1203 is executed.

At step S1203, the ANSW of FIG.
The key code of the question key, that is, the correct key, stored in the question key memory in step S1503 of FIG. 15 in the random number process of FIG. 6 in the ER time process is acquired. Then, from the human voice memory 106, the ADPC of the content representing the note name of the correct key
The audio data by the M method is read at the pitch of the correct key. Then, in the attack process of the next step S1204, a voice representing the answer is produced. For example, if the correct key is a key corresponding to the scale note of the note name C ₃ , then the voice having the content of "do" is pronounced at the pitch corresponding to C ₃ .

Thereafter, the correct answer MES progress process of step S1105 of FIG. 11 is terminated, and E of step S605 of FIG. 6 is executed.
The ND MESSAGE progress processing is ended, and step S6
The determination of 06 is NO and the determination of step S607 is YES, and the ANSWER time process of step S412 of FIG. 4 is terminated and the process returns to the main flow. Then, step S412 of FIG. 4 is executed again, and step S601 of FIG. 6 →
S602 → S604 (NO in step S901 of FIG. 9) → S605 → S1101 of FIG. 11 → S1102 →
The process returns to step S1201 of FIG. 12 through the route of S1105.

Since the answer voice representing the correct answer key has changed to the sounding state, the determination in step S1201 is N.
It becomes O, and the judgment in the next step S1205 becomes YES. During pronunciation of the answer voice, the next step S1206
It is determined whether or not there is silence. Then, while the answer voice is not silenced, this determination is NO, and the loop process similar to the above case is repeated, so that the answer voice is continuously sounded.

When this voice is silent, the determination in step S1206 becomes YES, and step 1207
Is executed. In step S1207, as the question message, the voice data according to the ADPCM method having the content of "next voice" is read from the human voice memory 106, and the message is sounded by the attack process in step S1208.

Thereafter, the correct answer MES progress process of step S1105 of FIG. 11 is terminated, and E of step S605 of FIG. 6 is executed.
The ND MESSAGE progress processing is ended, and step S6
The determination of 06 is NO and the determination of step S607 is YES, and the ANSWER time process of step S412 of FIG. 4 is terminated and the process returns to the main flow. Then, step S412 of FIG. 4 is executed again, and step S601 of FIG. 6 →
S602 → S604 (NO in step S901 of FIG. 9) → S605 → S1101 of FIG. 11 → S1102 →
The process returns to step S1201 of FIG. 12 through the route of S1105.

Then, since the question message has been changed to the sounding state, steps S1201 and 1205 are performed.
The determination is NO, and it is determined in the next step S1209 whether or not there is silence. Then, while the question message is not silent, this determination is NO, and the same loop processing as in the above case is repeated, so that the question message continues to be sounded.

When the question message becomes silent,
The determination in step S1209 is YES, and step 1
210 is executed. At step 1210, the current sequence flag is set to the “standby state” (see FIG. 10),
The correct MES elapsed process of step S1105 of FIG. 11 is terminated, and END MESSAGE of step S605 of FIG.
The progress process ends.

As described above, when the user's answer is correct, the voice of the answer is pronounced following the message "Seikai" and further "Next Tsudaidai".
Is pronounced.

The above processing is performed by the END MESSAG of FIG. 6 in the ANSWER time processing of step S412 of FIG.
This is the case where it is determined in step S1102 of FIG. 11 in the E progress processing that the correct answer is being sounded.
If it is determined that the correct answer is not being sounded by reading the incorrect answer message in 06, step S1
The processing of 103 is executed.

While "Zan-nen, Ichido-do" is being sounded, it is determined in the next step S1103 whether or not there is silence. While the message is not silent, this determination is NO and END ME in step S605 of FIG.
After the SSAGE progress process is completed, the determination in step S606 is NO and the determination in step S607 is YES, as shown in FIG.
The ANSWER time process of step S412 is finished and the process returns to the main flow. Then, again in step S4 of FIG.
12 is executed, and steps S601 → S602 → in FIG.
S604 (NO in step S901 of FIG. 9) → S
605 → S1101 → S1102 in FIG. 11, the process returns to step S1103.

By repeating the above-mentioned loop processing, the pronunciation of the message "Zan-nen, Ichido Ido" is continued. And when this message becomes silent,
The determination in step S1103 is YES, and step S
1104 is executed.

In step S1104, the current sequence flag is set to the "standby state" (see FIG. 10), and the END MESSAGE progress process of step S605 of FIG. 6 is terminated. <Explanation of the next question sound questioning operation in the concrete operation of the first embodiment> As described above, via step S1104 or step S1105 in FIG. 11 through step S1210 in FIG. E in step S605
After the NDMESSAGE elapsed process is completed, the sequence flag is currently set to the “standby state”, so that the determination in step S606 in FIG. 6 becomes NO, and then step S60.
The determination in step 7 is NO, and the determination in step S608 is NO.

Thus, by the operation already described,
The next question is given in the processing after step S609.
In this case, if the user's answer was the correct answer last time, the determination in step S609 becomes YES, the next problem sound is determined by the random number processing in step S610 described above, and the question sound is provided in the questioning processing in step S611. .. vice versa,
If the user's answer was incorrect last time, step S
The determination of 609 is NO, and the same problem sound as the previous time is given in the questioning process of step S611.

Here, as described above, step S4 of FIG. 6 within the ANSWER time process of step S412 of FIG.
In step S1306 in the ANSWER process of 619, it is determined whether or not the content of the variable indicating the number of consecutive correct answers exceeds a predetermined number N when the user's answer is correct, and if so, the next step is In S1307,
The contents of the variable indicating the question range are range I to range II until now.
Is changed to.

Therefore, when the user's answer is repeated N times, if the next problem sound is determined by the random number processing in step S610 in FIG. 6, step S1502 in FIG.
Is NO, and in step S1504, the random number memory value read in step S1501 is set to range I.
The remainder divided by the number of I is stored in the question key memory.

Here, when the question is given from the range I so far, as described above, the key code indicating one of the white keys is stored in the question key memory as a problem sound. On the other hand, the number of range II is the number of keys 103 in FIG.
The remainder value obtained by dividing the random number memory value by the number in the range II, which is equal to the total number of the white keys and the black keys, is nothing but the key code indicating either the white key or the black key. That is,
This remainder value is stored in the question key memory as the key code of the musical tone (question key) to be given.

As described above, when the user's answer is repeated N times, the problem sound also includes the scale sound of the black key, which increases the difficulty level. As described above, in the first example of the GAME mode, the user can enjoy the game in which the pitch of a single note is applied. Second Embodiment of GAME Mode Next, a second embodiment of the GAME mode will be described. <Description of Outline Operation of Second Embodiment> In the second embodiment of the GAME mode, the user can enjoy a game in which a chord, which is a kind of pitch game, is applied. In this case, the user listens to the chord given by the electronic keyboard instrument and answers the same chord by pressing the key.

In the first embodiment, the concepts of question range I and question range II were used, but the same applies to the second example. In this case, in the present embodiment, the chords to be given are triads, and when the question range I is selected, for example, only the long triad is given and the number of questions (chords) is 20. In addition, when the question range II is selected, for example, 20 questions of short triad chords are added to the question of the question range I, and a question is given out of a total of 40 chords. The difficulty level is increased.

When the user depresses the constituent tones of the chord to be the answer, even if the constituent tones are octave up or down, or if they form a revolving chord, the same tones are reproduced twice. Even if the key is pressed, the answer is correct. However, the time for the user to answer is limited to within 20 seconds as in the case of the first embodiment. The range of the electronic keyboard instrument used in this embodiment is F3 to C6,
Questions are also given from that range.

The operation flowchart showing the general operation of the second embodiment is almost the same as that of the first embodiment of FIG. 3, except that "do" is pronounced at the correct pitch in step S308 of FIG. Is the same, except that the chord "Do, Mi, Seo" is pronounced. <Common Part of Specific Operation of Second Embodiment and Specific Operation of First Embodiment> The configuration of the main flow of the second embodiment is the same as that of the first embodiment of FIG. In addition, the GAME MODE IN process of FIG. 5 of the first embodiment, the ANSWER time process of FIG. 6, the MODE IN progress process of FIG. 8, the question progress process of FIG. 9, the explanatory diagram of FIG. 10, the diagram E of FIG.
ND_MES progress process, correct answer MES progress process of FIG. 12,
And the END_MES process of FIG. 14 is basically the second
It is applied to the embodiment of.

In the second embodiment, the ANSWER TRIGGER processing of FIG. 7 and the A of FIG. 13 in the first embodiment.
Each process corresponding to the NSWER process, the random number process of FIG. 15, and the question process of FIG. 16 is different from that of the first embodiment.

In the following description, only the processing different from those of the first embodiment will be described. <Explanation of question chord questioning operation in concrete operation of the second embodiment> First, with reference to FIG. 17, a random number process for randomly determining one of the chords prepared in advance as a question will be described with reference to FIG. explain. This process is shown in FIG.
6 is executed as the process of step S610 in FIG. 6 in the ANSWER time process of step S412.

First, in step S1701, a predetermined random number memory value is read out and stored in the register X. This memory value is calculated and held by a random number generation process (not shown) at the timing when step S1701 is executed.

Next, in step S1702, it is determined whether or not the content of the variable indicating the question range is the range I.
First, the GAME MODE of step 404 in FIG.
Since the range I is initialized in step S504 of FIG. 5 in the IN process, step S1703 is executed. Here, the value 20 is set to the variable M indicating the number of questions.

In the case of the question range II, step S1704 is executed and the value 40 is set to the variable M indicating the number of questions. Next, in step S1705, the remainder obtained by dividing the random number memory value stored in the register X in step S1701 by the value set in the variable M in step S1703 or S1704 is newly stored in the register X. By this processing, the value of the register X is 0 to 19 when the number of questions is 20 (in the case of range I), and the number of questions is 4
If it is 0 (in the case of range II), one of the numerical values 0 to 39 is randomly selected.

Here, the data memory 107 which is a ROM
In FIG. 18, the key code of each constituent sound forming a chord corresponding to each group is written as shown in FIG. In the example of FIG. 18, C ₄ , E corresponding to C, D, and S in C major in order from the top
₄ , G ₄ chord, G ₄ , which also hits So, Si, and Re,
There are 20 sets of chords of chords in the range I, such as the long triads of B ₄ and D ₅ , which are relatively easy for the user to answer, and a total of 60 key chords from the offset addresses 10 to 69. It is written. Then, in FIG. 18, each key code of the short triad of range II is written after the key code corresponding to the above range I.

In order to randomly read out the three key codes of an arbitrary chord written in the data message 107 and generate a sound, the step S170 is performed.
6, the value of the register X is multiplied by the value 3, and the result is newly stored in the register X, and the subsequent step S170.
7, the value of register X is set to the variable TABLE OFF.
The offset address values of FIG. 18 stored in SET are added, and the addition result is stored in the register Y as the address of the key code at the beginning of any chord.

For example, when the question range I is selected, it is assumed that the remainder when the random number memory value is divided by the number of questions is 19, and this value 19 is multiplied by the value 3 to obtain the value 57.
When the offset address 10 is added to, the value 67 is obtained. This value 67 corresponds to the address of the key code (F _{5 in} the example of FIG. 18) at the beginning of the note constituting the problem chord.

Next, in step S1708, the variable i is initialized to the value 0. And first, step S
In 1709, the content corresponding to the register Y storing the above address value, that is, the first key code of the three key codes of the chord is the array Q_BUF as the first key code of the question key.

It is written in [0]. For example, in the example related to FIG. 18 described above, the key code of F ₅ , which is the content indicated by the address value 57, is Q_BUF.

[0]
Written in.

Next, until i = 3 (step S1
712), the variable i and each value of the register Y are incremented (steps S1710 and S1711), and the content indicated by Y is written in Q_BUF [i]. That is, in the example relating to FIG. 18 described above, the key codes of A ₅ and C ₆ which are the contents of the address values 58 and 59 are written in the arrays Q_BUF [1] and Q_BUF [2].

As described above, the key codes of the three tones forming the chord of the question key randomly selected are arrayed in the array Q_BUF.

[0], Q_BUF [1], Q_BUF
It is sequentially written in [2].

As the above processing, step S610 in FIG.
After the random number process of is executed, the questioning process of step S611 of FIG. 6 is executed. This process is shown in FIG.

First, the array Q_BUF is used as the question key.

The three key codes stored in [0], Q_BUF [1] and Q_BUF [2] are set in the tone key memory (step S1901). Then, the three kinds of musical tone data of the question key by the PCM method having the three key codes set in the pronunciation key memory are read by the time-division processing, and the attack processing simultaneously produces the sounds in the sense of hearing (step S1902). ).

In the next step S1903, the current sequence flag is changed from "standby" to a value indicating "in question" (step S1603). Subsequently, in step S1904, the key code buffer KC is an array in which the key code of the input key pressed by the user is written.
The contents of _BUR are cleared. This buffer will be described later.

Further, the counter S_CNT, which is a variable, is cleared (step S1905), and the flag S
_CNT_FLG is also cleared (step S190).
6). These two functions have already been described in the first embodiment.

Further, the key code counter KC_CNT that counts the number of keys pressed by the user is also cleared (step S1907). This will also be described later. in addition,
The release counter RL_CNT is cleared (step S1908). As described in the first embodiment, this counter is a time counter for causing the three musical tones to be presented to sound for 0.5 seconds each, and after the above clearing, this content is stored in the CPU 101 (FIG. 1). In particular, a timer (not shown) counts up.

Thereafter, the keyboard 103 of FIG. 1 is set in a key-depressable state (keyboard OFF) so that the key-depressing operation by the user is not accepted during the questioning (step S).
1909).

By the above processing, step S61 in FIG.
The questioning process of No. 1 is ended, the process returns to the main flow of FIG. 4, and the ANSWER time process of step S412 is ended. Since the keyboard 103 of FIG. 1 is in the key-depressable state as described above, the determination in step S408 is NO,
The process returns again to the ANSWER time process of step S412. The operation of the question progress process of FIG. 9 executed as step S604 of the ANSWER time process of FIG. 6 is the same as that of the first embodiment. <Explanation of Answering Operation of User in Specific Operation of Second Embodiment> Next, when the above-mentioned question progress processing is performed and the pronunciation of the problem chord ends, the keyboard is turned on (step of FIG. 9). (See S907), the state becomes "waiting for input" (ANSWER standby) from the user for a maximum of 20 seconds. The control operation at this time is similar to that of the first embodiment.

In the above "waiting for input" state, if the user presses the key for answering within 20 seconds after starting to pronounce the chord of the question key, the determination in step S409 of FIG.
S, and ANSWER TRIG in step S410
The GER process is executed. This process is shown in FIG.

ANSWER of FIG. 7 in the first embodiment
The TRIGGER processing is configured to correspond to one key pressed by the user, but the processing of FIG. 20 relating to the second embodiment can support a plurality of keys pressed by the user as an answer to a chord. Is configured as follows.

Further, it is possible to deal with both the case where the user simultaneously presses a plurality of keys or the case where the user sequentially presses one key at a time. That is, when the user presses only one key at one timing, the key code corresponding to only that one key is acquired as the value of the variable KC in step S2001, and the subsequent processing is executed. On the other hand, when the user presses a plurality of keys at the same time, the state in which the determination in step S2015 becomes NO is repeated, so that the key code corresponding to each key is a variable K in step S2001.
The values of C are sequentially acquired, and the subsequent processing is sequentially repeated.

After the key codes are sequentially acquired one by one in step S2001, step S20 is performed.
In 02, the value 12 is subtracted from the value of the variable KC storing the key code and is newly stored in the variable KC.
Next, in step S2003, the value of the subtraction variable KC is either less or not from the key code of the key of the pitch name F ₃ is determined. If it is not smaller, the process returns to step S2002, and the value 12 is again subtracted from the value of the variable KC. In this way, every time the process passes through step S2002, the value 12 is subtracted from the value of the variable KC storing the key code, and when the value of the variable KC becomes smaller than the key code of the key of F ₃ , in step S2004. , The value 12 is added to that value.

For example, if the user presses the key C ₅ (KC = 72), 72-12 = 60 is not smaller than the key code 53 of the F ₃ note, so 60 to 12 is further subtracted and 48 is the key code. (Corresponding to C ₃ ). Since this 48 is smaller than the F ₃ key code 53,
12 is added to this 48, and a key code 60 (corresponding to C ₄ ) is obtained.

In this way, the key code in the lowest octave (the range of F _{3 to} F ₄ in this embodiment) corresponding to the key code of the key pressed by the user is obtained. Next, by the processing of step S2005 and thereafter,
The key code obtained in the variable KC is sequentially stored in the key code buffer KC_BUF which is an array. That is, if the user presses three keys, the key code buffer KC_B
UF

Three key codes are sequentially stored in [0] to KC_BUF [2]. However, even if the user repeatedly presses the same key, the processing is executed so that the key press is ignored.

First, in step S2005, the pointer i indicating the content of the key code buffer KC_BUF [i] is cleared. Next, step S2006
Then, the key code buffer KC_BUF [i] = KC_B
UF

It is determined whether the content of [0] is equal to the value of the key code stored in the variable KC.

First, the key code buffer KC_BUF
19 is included in the question processing in step S611 in FIG. 6 in the ANSWER time processing in step S412 in FIG.
The key code buffer KC_BUF has been cleared in step S1904 of

[0] contains an initial value. Therefore, the determination in step S2006 is NO, and step S2007 is executed. Here, the value of the pointer i and the value of the key code counter KC_CNT are compared.

The key code counter KC_CNT is a counter indicating how many keys have been pressed by the time when the ANS_TRIGGER processing of this time is finished. The content of the key code counter KC_CNT is the step S611 of FIG. 19 in the question processing of FIG.
The value has been cleared to 0 at 07. Therefore, initially, the determination in step S2007 is YES.

In the following step S2009, the value of the key code counter KC_CNT is incremented and the value becomes 1. Next, in step S2010, it is determined whether or not the value of the key code counter KC_CNT exceeds 3.

Since it does not exceed 3 at first, it is determined in the next step S2011 whether the flag S_CNT_FLG is 1 or not. If this judgment is NO, Step S20
12, the flag S_CNT_FLG is set to 1, and the determination is Y.
If it is ES, the process proceeds to step S2013. The meaning of this control processing is the step S701 of FIG. 7 in the first embodiment.
And S702.

In step S2013, the current key code stored in the variable KC is the key code buffer KC.
_BUF [KC_CNT-1]. here,
The value of the key code counter KC_CNT is determined in step S20.
Since the value is set to 1 in 09, the subscript [KC_CNT-
1] has a value of 0. As a result, the key code buffer KC
_BUF

The content of the variable KC, that is, the key code of the first key depressed by the user is stored in [0].

If the user is pressing two or more keys at the same time, the determination in step S2015 is N.
When it becomes O, the process returns to step S2001, and the same processing as the above case is repeated.

On the other hand, if the user is pressing only one key at one timing, the determination in step S2015 is YES. As a result, in step S410 of FIG.
The NSWER TRIGGER processing is ended, and the process returns to the main flow.

Thereafter, S411 of FIG. 4 → S412 → FIG.
S601 → S602 → S604 → S901 in FIG. 9 → S605 in FIG.6 → S1101 in FIG.11 → S606 in FIG. →
S607 → S608 → S612 → S616 → S4 of FIG.
13 to S415 → S40S → S407 → S408 → S4
09-> S411 route, "waiting for input" after the second key
State (ANS standby state) (see FIG. 10) is continued.

When the user presses the key for answering the second key within 20 seconds after starting the pronunciation of the chord of the question key, the determination in step S409 in FIG. 4 becomes YES,
ANSWER TRIGGER in step S410 again
The process is executed, and the operation flow of FIG. 20 is executed.

If the user does not press the second key or the third key within 20 seconds after starting the pronunciation of the chord of the question key, the ANSWE of step S412 of FIG.
The determination in step S612 in FIG. 6 in the R time processing is YES.
Becomes The subsequent processing is the same as in the case of the first embodiment.

Next, it is executed by the user pressing the second key at the same time, or by pressing the second key following the key pressing of the first key. Figure 2
The processing of the operation flow of 0 will be described.

Since steps S2001 to S2005 are the same as the case of the first key, the description thereof will be omitted. In step S2006, the key code of the second input key stored in the variable KC and the key code buffer KC_
BUF [i] = KC_BUF

It is determined whether or not the key code of the first key stored in [0] matches.

Here, if the key code buffer KC_B
UF

If the contents of [0] and the contents of the variable KC match,
Since the same key is continuously pressed, the determination in step S2006 is YES in this case, the ANSWER TRIGGER processing in step S410 in FIG. 4 is terminated, and the process returns to the main flow. That is, when the same key is continuously pressed, the key is ignored.

If the second key is different from the first key, the key code buffer KC_BUF

Since the content of [0] and the content of the variable KC do not match, the determination in step S2006 is NO.

Next, in step S2007, the value of the pointer i and the value of the key code counter KC_CNT are compared. At present, the pointer i has the value 0 in step S2005, and the value of the key code counter KC_CNT has been set to the value 1 in step S2009 which is the first key process. Therefore, the determination in step S2007 is N
It becomes O, the pointer i is incremented in the next step S2008, and its value becomes 1.

As a result, in step S2006, the key code buffer KC_BUF [i] = KC_BUF [1].
And the content of the variable KC are compared. Here, the content of the key code buffer KC_BUF [1] is the same as the step S1904 in FIG. 19 in the question processing in step S611 in FIG. 6 in the ANSWER time processing in step S412 in FIG.
Remains cleared at. Therefore, step S
The determination of 2006 is NO.

The determination in the next step S2007 is YES because both the value of the pointer i and the value of the key code counter KC_CNT are 1. Continued Step S
In 2009, the value of the key code counter KC_CNT is incremented, and the value becomes 2.

Next, in step S2010, it is determined whether or not the value of the key code counter KC_CNT exceeds 3. At present, since it has not exceeded 3, the determination is NO. Then, through the same steps S2011 and S2012 as the case of the first key process, step S2013 is executed.

In step S2013, the key code of the second key stored in the variable KC is stored in the key code buffer KC_BUF [KC_CNT-1].
Here, since the value of the key code counter KC_CNT is set to the value 2 in step S2009, the subscript [KC_C
NT-1] has a value of 1. As a result, the contents of the variable KC, that is, the key code of the second key pressed by the user is stored in the key code buffer KC_BUF [1].

Next, the user presses the third key at the same time as the first key or the second key, or continues after the second key is pressed, and the third key is continued. The process of the operation flow of FIG. 20 executed by pressing the key will be described.

In this case as well, the processing is the same as when the second key is pressed. That is, step S2
After the processing of 001 to S2005, step S2006
By the loop process of → S2007 → S2008 → S2006, the key code of the third input key stored in the variable KC is changed to the key code buffer KC_BUF.

It is sequentially determined whether or not the key codes of the first key and the second key stored in [0] and KC_BUF [1] match.

If any of the keys matches, it means that the same key as the first key or the second key has been continuously pressed, so that the determination in step S2006 becomes YES, and ANSWER in step S410 in FIG. 4 is performed. The TRIGGER processing is ended, and the process returns to the main flow. That is, when the same key is continuously pressed, the key is ignored.

If neither matches, the determination in step S2007 of the second round of the loop processing is YES, and in step S2009 the key code counter KC_C.
After the value of NT is incremented to 3, step S2
Step S2013 is executed through 010 to S2012.

In step S2013, the key code of the third key stored in the variable KC is stored in the key code buffer KC_BUF [KC_CNT-1].
Here, since the value of the key code counter KC_CNT is set to the value 3 in step S2009, the subscript [KC_C
NT-1] has a value of 2. As a result, the content of the variable KC, that is, the key code of the third key pressed by the user is stored in the key code buffer KC_BUF [2].

As a result of the above processing, the key codes of the depressed three keys are stored in the key code buffer KC_BUF.

[0], K
The data is sequentially stored in C_BUF [1] and KC_BUF [2].

The above is the normal case where the user presses three keys, but the case where the user accidentally presses four keys will be described below. When the fourth key is pressed, the second key
Similar to the case of the key and the third key, steps S2001 to S2001
S2008 is executed, and in the subsequent step S2009, the value of the key code counter KC_CNT is incremented, and the value becomes 4.

As a result, the key code counter KC_CN
The value of T becomes larger than 3, the determination in step S2010 is YES, and the correctness flag is set to "erroneous" in subsequent step S2014.

By the above processing, if the user mistakenly presses the four keys, the correctness flag is forcibly set to "erroneous", and an incorrect answer processing is performed in the ANSWER processing described later. <Description of Correct Answer / Incorrect Answer Processing in Specific Operation of Second Embodiment> ANS in step S410 of FIG. 4 described above.
In the _TRIGGER processing, the flag S_C is set in step S2012 of FIG. 20 in response to the pressing of the first key.
When 1 second elapses after NT_FLG is set to 1,
The determination in step S616 in FIG. 6 in the ANSWER time process in step S412 of step S412 is YES. This allows
Via steps S617 and S618, step S
The ANSWER process of 619 is executed. That is, even if the second key and the third key are not pressed, the ANSWER process is executed. This is so that even if the user is inputting an answer key, if the key entered up to that point does not match any of the question keys in the chord in question, the incorrect answer can be processed immediately. This is because

The ANSWER process is shown in FIG.
First, in step S2101, it is determined whether the correctness flag is “erroneous”.

As described above, when the user mistakenly presses the four keys, the ANSWE in step S410 of FIG.
Step S201 in FIG. 20 in the R TRIGGER process.
At 4, the correctness flag is forcibly set to "erroneous." In this case, the determination in step S2101 is YES, and an incorrect answer process is immediately performed in the ANSWER process described later.

If the number of keys pressed by the user is less than four, the determination in step S2101 becomes NO, and step S2101
The processing after 2102 is executed. First, step S2
At 102, the pointer i is cleared.

Next, in step S2103, the key code buffer KC_BUF

The content of [0], that is, the content of the first key pressed by the user is transferred to the register X.

Next, in step S2104, the pointer j is cleared. Then, step S2106
While the pointer j is sequentially incremented at
Steps S2105 → S2106 → S2107 → S21
In the loop processing of 05, an array Q_BUF in which the contents of the variable X and the key code of the question key (key corresponding to the chord to be questioned) are stored

[0] to Q_BUF
The contents of [2] are sequentially compared.

Here, the content of the variable X is Q_BUF.

If none of [0] to Q_BUF [2] match, the following reasons can be considered. That is, the key code buffer KC_BUF storing the key code of the key pressed by the user (input key) is stored in the ANSWER TRIGGER processing of step S410 of FIG. 4 described above by the processing of steps S2002 to S2004 of FIG. , The key code in F _{3 to} F ₄ of the lowest octave is stored. For example, if the key pressed by the user is C ₅ , the key code is converted into a C ₄ key code one octave lower and stored in Q_BUF.

On the other hand, it is unknown which octave key the question key is. Therefore, the cause of the mismatch in step S2105 may be the octave difference. In order to deal with the above possibility, the content of the variable X is Q_B
UF

If none of [0] to Q_BUF [2] match, after the determination in step S2107 becomes YES, in step S2108, the value of the variable X in which the key code of the input key is stored corresponds to one octave. The value 12 is added to obtain a new value for the variable X.

Then, after returning to step S2104 again, steps S2105 → S2106 → S2107 → S
In the loop processing of 2105, Q_BUF containing the content of the variable X and the key code of the question key (key corresponding to the chord to be questioned) to be given

[0] to Q_BUF [2] are sequentially compared.

As a result of increasing the value of the variable X by octaves as described above, if the value of the variable X exceeds the key code value of the highest note C ₆ , the determination in step S2109 becomes YES and this The correctness flag is set to "erroneous" for the first time (step S2110).

In this way, the user has not entered all the three keys to be the answer, and even while inputting, considering the difference in octaves, the chords that have been input up to that point are problematic chords. If none of the keys matches, the correctness flag is set to "wrong" in step S2110, and then an incorrect answer process is executed by the END_MES process of step S2115.

In the loop processing of steps S2105 to S2107, the content of the variable X is Q_BUF.

[0] -Q
If any of _BUF [2] matches, the determination in step S2105 is YES, and the next step S2
Proceed to 111. In this state, at least the first key matches any one of the question keys.

If the user has also pressed the second key as the answer, the pointer i is incremented in step S2111, and the determination in step S2112 is NO.
Then, the same comparison process as the first key is executed. The same applies to the third key.

If the user has not yet pressed the second key or the third key as the answer, after the determination in step S2112 becomes YES, the determination in step S2113 is N.
When it is O, the correct answer is not determined, and step S6 in FIG.
The ANSWER process of 19 is terminated, and step S4 of FIG.
The 12 ANSWER time processing is ended, and the process returns to the main flow. After that, S413 to S415 of FIG. 4 → S40S
→ S407 → S408 → S409 → S411 → S412
→ S601 of Fig. 6 → S602 → S604 → S90 of Fig. 9
1 → S605 in FIG. 6 → S1101 in FIG. 11 → S6 in FIG.
06 → S607 → S608 → S612 → S616 → FIG. 4
In the path of S413, the state of "waiting for input" (ANS standby state) after the second key is continued (see FIG. 10).

The user sequentially presses the second key and the third key as the answers, and the ANW of step S410 of FIG. 4 is entered each time.
By executing the ER TRIGGER processing (see FIG. 20), the key codes of the three keys pressed by the user are stored in the key code buffer KC_BUF.

[0], KC_B
It is stored in UF [1] and KC_BUF [2]. Immediately after that, ANSW in step S412 of FIG.
Answe of step S619 in FIG. 6 in the ER time process
The R process is executed, and the key code buffer KC_BUF is repeated by repeating steps S2103 to S2112.

[0], KC_BUF [1] and KC_BUF [2]
All three keycodes stored in are Q_BUF, taking into account the octave difference.

[0] to Q_BUF
When it is determined that the contents match with the contents of [2], step S2
The determination at 113 is YES.

As a result, the correctness / incorrectness flag is set to "correct" in step S2114, and the correct answer process is executed by the subsequent END_MES process in step S2115.
The END_MES process of step S2115 is shown in FIG. 14 and is the same as that of the first embodiment.

Then, in step S2115, END_M.
The ES process is completed, and ANSW in step S619 in FIG.
The ER process ends. Then, returning to FIG. 4 of the main flow, after finishing the ANSWER time process of step S412, the process proceeds to step S402 → S407 → S408,
Further, since the keyboard is currently off (see step S1403 in FIG. 14), step S40
After the determination of 8 is NO, the ANSWER time process of step S412 is executed again. In the ANSWER time process, steps S601 → S602 → of FIG.
The process proceeds from S604 (NO in S901 of FIG. 9) to S605, and the END MESSAGE progress process is executed.
This process is shown in FIG. 11 and is almost the same as in the case of the first embodiment.

However, the following points are different. That is, the process of step S1203 of FIG. 12 in the correct MES progress process of step S1105 of FIG. 11 is different from that of the first embodiment. In the first embodiment, the voice of the answer pronounced here is a voice having the content of, for example, "dow" which represents one correct key, but in the second embodiment, the correct key of 3 is used.
After the key codes of the two keys are acquired, the pitches corresponding to the key codes, for example, sounds of "do, mi, se" are continuously produced.

As described above, the second GAME mode is performed.
In this embodiment, the user can enjoy the game in which the pitch of each constituent note of the chord is applied. Third Embodiment of GAME Mode Next, a third embodiment of the GAME mode will be described. <Outline of Operation of Third Embodiment> In the third embodiment of the GAME mode, the user can enjoy a game in which a rhythm pattern of music automatically played by an electronic musical instrument is applied. In this case, as shown in FIG. 22, various rhythm names are displayed corresponding to each key of the electronic keyboard instrument, and the user answers by pressing the key corresponding to the rhythm name to be applied.

The operation flowchart showing the schematic operation of the third embodiment is almost the same as that of the first embodiment of FIG. 3, but the processes of steps S303 and S308 of FIG. 3 are omitted. <Common Part of Specific Operation of Third Embodiment and Specific Operation of First Embodiment> The configuration of the main flow of the third embodiment is the same as that of the first embodiment of FIG. In addition, the ANSWER TRIGGER process of FIG. 7 of the first embodiment, the explanatory view of FIG. 10, the END_MES progress process of FIG. 11, and FIG.
The ANSWER process of No. 3 and the random number process of FIG. 15 are applied to the third embodiment in principle.

In the third embodiment, the GAME MODE IN processing of FIG. 5 and the ANSW of FIG. 6 in the first embodiment.
Each process corresponding to the ER time process, the correct answer MES progress process of FIG. 12, the END_MES process of FIG. 14, and the questioning process of FIG. 16 is different from that of the first embodiment.

In the third embodiment, the question progress process of FIG. 9 and the MODEIN progress process of FIG. 8 are deleted. In the following description, only the processing different from those of the first embodiment will be described. <GAME MOD in the concrete operation of the third embodiment
Description of E IN Process> First, the GAME MODE IN process executed as step S404 in FIG. 4 will be described. This process is shown in FIG.

Steps S2301 and S230 of FIG.
2, S2303, and S2304 are performed in steps S501, S502, and S in FIG. 5 according to the first embodiment.
This is the same as the processing of 504 and S505.

However, in the processing of FIG. 23, there is no processing corresponding to step S503 of FIG. This is shown in FIG.
This is because the MODE IN progress flag is deleted in the 4 ANSWER time process, and thus the MODE IN in-progress flag becomes unnecessary.

Further, in step S506 of FIG. 5 in the first embodiment, the voice data by the ADPCM system having the content of "this sound, what?" Was read from the human voice memory 106. In step S2306 of FIG. 23 in the example, the audio data by the ADPCM system having the content of "this rhythm what?" Is read. Then, this voice message is sounded by the attack process of step S2307 <Description of ANSWER time process in specific operation of the third embodiment> Next, ANS of step S412 of FIG.
The WER time processing is shown in FIG.

The processing of FIG. 24 corresponds to that of the first embodiment.
24 is different from the processing in FIG. 24 in step S6 in FIG.
02, the MOD of FIG. 8 that is step S603.
That is, there is no process corresponding to the EIN progress process, the question progress process of step S604, and the “during question?” Determination process of step S606.

First, the reason why the processes corresponding to the determination process of step S602 of FIG. 6 and the MODE IN progress process of FIG. 8, which is step S603, are eliminated is that the first embodiment is a sound hitting game. At the start of the mode, the scales that are the reference of the pitch are sequentially pronounced so that the user can easily answer, while the third example is a rhythm hitting game. Because it is not necessary.

Further, the reason why the processes corresponding to the question passing process in step S604 and the "during question?" Determination process in step S606 in FIG. 6 are eliminated is as follows. That is, when a single note is given in the first embodiment, the produced question sound is muted and then the answer is waited for. However, when the rhythm pattern of the third embodiment is given, Even if the problem rhythm is being pronounced, you can answer as soon as you understand the answer. For this reason, the processing corresponding to steps S604 and S606 of FIG. 6 for waiting for the end of the pronunciation of the problem sound is unnecessary.

Other than that, step S240 in FIG.
1, S2402, and S2403 to S2415 are performed in steps S601, S605, and S6 of FIG.
The flow configuration is the same as that of each processing of 07 to S619.

Of the above flow configuration, the questioning process of step S2407 of FIG. 24 shown in FIG. 25 is slightly different from the process of step S611 of FIG. 16 shown in FIG. 16 in the first embodiment. <Explanation of the questioning process in the specific operation of the third embodiment>
That is, in step S2501 of FIG. 25, the rhythm pattern corresponding to the key code stored in the question key memory by the random number process of step S610 of FIG. 6 (see FIG. 15) in the ANSWER time process of step S412 of FIG. It is called from the data memory 107 which is the ROM of FIG. Then, in step S2502, the start of the performance based on the rhythm pattern is instructed. As a result, the performance of the problematic rhythm pattern is started in the tone generation circuit 110 of FIG.

Here, in the third embodiment, in order to receive the key pressing operation (answering operation) by the user immediately after the start of the performance of the rhythm pattern, the current sequence flag is set to "standby state" in step S2503. , And in step S2507, the keyboard 103 of FIG. 1 is brought into a key-depressible state (keyboard ON).

Other steps S2504 to S25 of FIG.
Each processing of 06 corresponds to steps S1604 to S16 of FIG.
This is the same as each process of 06. Since the determination in step S408 of FIG. 4 is YES after the above-mentioned rhythm pattern has been asked, the user can immediately use the keyboard shown in FIG. 22 to answer the rhythm pattern. When the user presses any key to answer the rhythm pattern, the ANSWER TRIGGER processing (see FIG. 7) of step S410 of FIG. 4 is executed, as in the case of the first embodiment, and further, AN in step S412 of FIG.
A in step S2415 of FIG. 24 in the SWR time processing
NSWER processing is executed. A in step S2415
As in the case of the first embodiment, the NSWER processing is performed as shown in FIG.
Indicated by. <Description of END_MES Process in Specific Operation of Third Embodiment> Here, step S2411 of FIG. 24 shown as FIG. 26 or E of step S1310 of FIG.
The ND_MES processing is slightly different from that shown as FIG. 14 in the first embodiment.

That is, steps S2601 to S2601 in FIG.
S2608 corresponds to steps S1401 to S140 of FIG.
Although it is almost the same as step 8, except for the processing in step S2603, in which the keyboard 103 of FIG. The process of stopping the pronunciation of the rhythm pattern, which has been pronounced as a problem until now, is executed. <Explanation of Correct MES Progression Process in Specific Operation of Third Embodiment> Finally, ANSW in step S412 of FIG.
END in step S2402 of FIG. 24 in the ER time process
The MESSAGE progress process is shown as FIG. 11 as in the case of the first embodiment. However, the correct MES progress process of step S1105 of FIG. 11 shown as FIG. 27 is slightly different from that of FIG. 12 in the first embodiment.

That is, in the first embodiment of FIG. 12, the voice of the answer uttered in steps S1203 and S1204 is a voice having the content of, for example, "do" which represents one correct key. In the third embodiment of No. 27, after the rhythm name of, for example, “March” corresponding to the key code of the correct key is acquired in step S2703, the attack process of step S2704 is performed, and the voice having the rhythm name as the content is acquired. Is pronounced.

Step S other than Step S2703
Each processing of 2701 to S2710 is performed in step S120 other than step S1203 of FIG. 12 in the first embodiment.
This is the same as each process of 1 to S1210.

As described above, the third GAME mode is performed.
In this embodiment, the user can enjoy the game in which the rhythm name corresponding to the rhythm pattern is applied. Other Embodiments In the three embodiments described above, the time limit for the user to answer is set to 20 seconds, but the time is not limited to this, and for example, the time limit is shortened according to the number of consecutive correct answers. You can also do so.

Further, if a display device for indicating the remaining time of the time limit, such as an LED, is provided on the front surface of the electronic musical instrument,
It is beneficial to the user. Further, in the above-described embodiment, when the user does not answer within the time limit, the same question is repeatedly asked, but another question having the same difficulty level may be given. Good.

[0219]

According to the first aspect of the present invention, it becomes possible to enjoy a game of questions / answers for chords.

According to the second aspect of the present invention, the user is
The reference sound for the problem sound can be learned in advance, and the learning ability of "listening sound" can be efficiently improved. Further, according to the third aspect of the present invention, if the user does not input all the keys of the answer sound for a predetermined time limit or longer, the answer operation by the user is determined to be an incorrect answer and the question sound is advanced. Therefore, it is possible to perform an efficient questioning operation.

Further, according to the fourth aspect of the present invention, when the frequency of correct answers by the user increases, for example, a set of problem sounds composed of chord constituent sounds of higher difficulty can be presented, and It is possible to gradually improve the "listening sound" ability of the.
