Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic musical instrument that allows players to play a game of guessing the front of a movement by pressing a key, and is suitable for music education for beginners and the like.

In general, in music education for beginners, etc., it is preferable to add game-like elements so that music can be naturally developed in a fun way.

However, conventional electronic musical instruments lack game elements and are not sufficient for music education for beginners.

An object of the present invention is to provide a novel electronic musical instrument that incorporates game-like elements in order to enhance the effectiveness of music education.

The electronic musical instrument according to the present invention is characterized by generating a pre-movement pattern that changes along the longitudinal direction of the keyboard, and by pressing keys on the path before the movement, the user can enjoy a game of guessing the notes. Hereinafter, embodiments shown in the accompanying drawings will be described in detail.

Figure 1 shows an electronic musical instrument according to an example of the present invention.

When the game select switch SW is off, key press data from the keyboard circuit 10 including the M-key keyboard is transferred to the Hiro inverter 1.
Gate circuit 1 is conductive due to the output signal of 2 = 111
4 to the sound collection forming circuit 16. The sound collection forming circuit 16 forms a round string sound signal corresponding to the pressed key according to the key press data from the gate circuit 14 and supplies it to the speaker 18, so that the sound signal corresponding to the pressed key is output from the speaker audience. A sound collection is generated.

Therefore, in this case, normal manual playing is possible on the keyboard.

When the game select switch 8W is turned on, the output signal of the inverter becomes non-conductive and the gate circuit 14 becomes non-conductive. For this reason, normal manual performance on the keyboard is no longer possible. However, the ON signal of the switch SW is the game l! Since it is supplied to the iMI as an enable signal EN, the game circuit becomes operable, and the user can enjoy playing a guessing game by pressing keys on the keyboard.

Next, the operation of the game circuit will be explained with reference to diagram f142.

When the start switch 8W@, which is a self-resetting pushbutton switch, is pressed, a start signal 8T is generated, and the timer circuit n starts timing a predetermined game time. Also,
Since the start signal ST is supplied as a preset signal PR1 to the variable frequency divider which inputs the lock signal φ, initial frequency division ratio data is preset to the variable divider from the register, and the variable frequency divider The clock signal φst is divided by the frequency division ratio indicated by the initial power division ratio data and sent out.

Start signal 8TIfi, programmable up/down signal via OR gate Z and delay circuit (equipment)
counter! Since the preset signal PR is supplied to the counter proverb, the random pitch data RD is preset from the random pitch data generator A. Then, the output signal of the delay circuit is connected to the delay circuit and the OR gate 38t-
Since the random pitch data RD is supplied as a load signal LD to the register 40 via the random pitch data generator U, the random pitch data RD is loaded into the register 40 from the random pitch data generator U.

D Indicates the starting pitch of the pitch data moving note (hereinafter abbreviated as M note) preset in the counter proverb, and is supplied as input B to the comparison circuit 42.

Further, the pitch data which is loaded into the register indicates the destination pitch of the fiM tone, and is supplied to the ratio IIRIg circuit 42 as an input signal. The comparison circuit company compares the input cam and B at this time and generates an output signal corresponding to either M = B or M (B, M > B. Here, the destination pitch and the departure sound are If HIGH and MU; High data is loaded and table operations are performed in this manner until M and B no longer match.

Furthermore, if the destination pitch is lower than the departure pitch, and if it is MukuB, the output signal of the comparison circuit 42 is supplied to the counter as a down mode designation signal via the gate circuit 44 and the OR gate The ground pitch is higher than the starting ground pitch.
If B, the output signal of the comparison circuit 42 is supplied to the counter n as the up mode designation signal U via the gate circuit material and the OR gate 48.

By the way, since the R-87 flip-flop for start/stop control is set via the output signal FiOR gate group of the slow grinding circuit, when the flip-flop area is set, the gate is set by the output Q=%II. Make circuit N conductive. Therefore, the clock signal φ from the variable frequency division loss is supplied to the counter n as a clock input OK via the gate circuit xi and the OR gate group. Therefore, the counter blade is activated by the mode designation signal or by the clock signal φ1 in either the down or up mode specified by U.
, the M sound data MD is counted as the counting output.
indicates a pitch that changes to either the bass side or the treble side along the longitudinal direction of the keyboard.

counter! Input B to the M sound data MDd comparison circuit
On the other hand, it is supplied to a musical tone forming path 16 and converted into a musical tone signal. Therefore, the speaker 18 produces a series of musical tones that seem to move in response to the change in pitch of the M tone data.

With the generation of such a series of musical tones, the first pitch is started by pressing a key on the keyboard that is on the path of the moving tones.

At this time, since the output Q-%1'#i of the flip-flopper is supplied to the data acquisition circuit ω as a data acquisition command signal, the data acquisition circuit 60 indicates the key pressed on the Hiro keyboard. Data is taken in from the keyboard circuit 10. Here, even if multiple keys are pressed on the keyboard, the data acquisition circuit ω gives priority to the key press data corresponding to one of them (the key pressed earlier, or the key on the higher or lower pitch side). It is designed to be taken in as a target.

Key press data KD corresponding to one key from data acquisition circuit ω
is supplied to the comparison circuit section as an input signal, and is also supplied to the musical tone forming circuit 16, where it is converted into a musical tone signal. Therefore, the speaker 18 produces a musical tone corresponding to one key indicated by the key press data KD.

The key press data KDd from the data acquisition circuit ω is also supplied to the OR gate 62, and in response, a key-on signal KON is generated from the OR gate section. This signal KON is converted into a pulse synchronized with the key press timing by the rising differential circuit, and this pulse causes the flip-flop # to be reset via the OR gate 6. Therefore, the gate circuit 8 becomes non-conductive, the counter stops incrementing, and the data acquisition circuit ω is prohibited from incorporating data. Then, an output signal corresponding to the comparison result of the input cam and B is sent from the comparison circuit section.

Now, assuming that the pitch indicated by the M tone data MD and the pitch indicated by the key press data KD match, the comparator circuit section converts the output signal corresponding to M; Supply to input solder. The other input terminal of the AND gate is supplied with a pulse synchronized with the release II (or take-in prohibition) timing from the falling differentiation circuit 70 that receives the key-on signal KON. 4% compared to lnJ period! - Send out the output signal corresponding to M=B from the road group as the correct signal G. This correct answer signal Gm enables the correct sound data generation circuit 72 to supply the correct sound data to the musical tone forming circuit 16, so that the correct sound is generated from the speaker 18. Also, the correct answer signal GAI
Since the Ii accumulator 74 is supplied as a load signal, the take corresponding to 5 points is loaded from the register 76 to the accumulator 74, and the score display 78 displays that 5 points have been obtained. And, the positive S-Tokugaku Gmu is the delay circuit 77 and the AN
The start signal 8' is sent out through the D gate 79, and is supplied to the delay circuit (9) through the OR gate, so that it is possible to move on to the second note guess in the same way as described above. .

On the other hand, if it is assumed that the pitch indicated by the M note data MD and the pitch indicated by the key press data KD gradually match, the comparison circuit indicates that the M note is at the 69th or 69th note on the keyboard, counting from the lowest key. Is it within the key range? If it is not within that range, the output signal corresponding to 6≦B≦branch is added to %Ql, and this output signal = %0IFi is the signal s1 at the inverter.
converted to z.

Then, the output signal terminal %11 from the inverter (capital) is conducted by the output signal of the inverter core = %II.
The signal is sent out as an incorrect answer signal B through the D gate 84, through the MD gate 86t which becomes conductive in synchronization with the key release timing, and through the OR gate 88. This incorrect answer signal B causes the flip-flop 52 to be set via the OR game 50, so that the counter resumes incrementing and the data acquisition circuit also resumes data acquisition.

Therefore, in this case, the first note guess is set as 0 points and the second note guess is performed.

Furthermore, when the comparator circuit generates an output signal = 111 indicating that the condition 6≦B<32 is satisfied, the AND gate outputs the output signal corresponding to 6≦B≦ and the output signal of the inverter 82. Conduct. At this time, the comparison circuit checks whether the pressed key is within 5 keys on the high or low side of the M note, and if it is not within that range, (B-5) ≦ M ≦ (
The output signal corresponding to B+5) becomes %QI, and this output signal=%Ql is converted into signal 111 by an inverter. Then, the output signal from the inverter snake = t I J
F is sent as an incorrect answer signal B through the MMD gate, further through the MND gate 94 which becomes conductive in synchronization with the key release timing, and further through the OR gate 88. Therefore, in this case as well, the second sound guess is performed, as in the case of the generation of the incorrect answer signal described above.

By the way, when the comparison circuit generates an output signal = %11 indicating that the condition (B-5)≦Mu≦CB+5) is satisfied, the ND gate % corresponds to 6≦B≦B and 9 outputs. Since it is electrically connected by the signal and the output signal of the inverter area, (B-5)<mu≦CB+5)K corresponding output signal=
% l l is AND game through mu IJD gate %)
98 and 100.

These AND gates % and 100 are designed to receive pulses synchronized with the key release timing from the falling differentiation circuit 70, and the AND gates receive pulses A) from between the comparison circuits.
An output signal corresponding to B is supplied, and ANI) game) 1
00 is supplied with an output signal corresponding to A (B) from the comparator circuit section. Therefore, in the case of M>B, where the pitch of the pressed key is higher than the pitch of M note, the AND gate box outputs the falling signal CD. If the pressed key pitch is A (B), which is lower than the pitch of the M note, the AND gate 100 generates a rising signal 0.

When either the rising signal ay or the falling signal CD is generated, these signals Ct+ and On! The OR gate 102 as an input generates an output signal; 111, and this output signal =
=%11 is converted into a differential pulse by the rising differential circuit 104 and resets the color/return signal 106.

After this reset, the counter 106 receives the clock signal φB.
The clock signal φm, which is faster than the clock signal φ, is counted by 6. Since the R-8 flip-flop 108 is set at the first count of the counter 106, the R-8 flip-flop 108 is set.
The output Q=Turtle II of 08 makes the gate circuit 110 conductive, while making the gate circuit I non-conductive via the inverter 112'i. Therefore, the gate circuit 110 is installed on the counter support.
A high-speed clock signal φm is supplied through the OR gate) 56t, and the counter performs a high-speed counting operation in response to this.The counting mode of the counter at this time is the falling signal CD from the OR gate weak or the OR gate Rising signal C from Tsuge
t depending on σ! If the signal CD is generated, the mode is down mode, and if the signal OU is generated, the mode is up mode.

When the counter 106 counts the clock signal φmt-6, the flip-flop 108 becomes conductive in response to this, and the gate circuit 44 becomes conductive, and the gate circuit 110 becomes non-conductive. Therefore, the counter proverbially substitutes the low-speed clock signal φB for the high-speed clock signal φM, and its counting mode is controlled according to the output signal of the gate circuit. As a result, the counter! is 7 lip flops 1osi: After being set, the high-speed lock signal φm i5 has been counted, and along with this, the M note data MD shows a pitch change of 5 keys at high speed, so the M note is also related to 5 keys. This means that the key has been moved. In this case, the moving direction of the M sound is the bass direction or the treble direction depending on the descending signal On or the ascending signal On, respectively.
In any case, the direction is away from the key pressed position.

Even when the rising signal Ou or the falling signal CD is generated as described above, if the score is FiO point, the player moves quickly due to the M sound and then moves to the second sound guess.

The same operation as described above is performed for the second and subsequent note guesses, and each time a correct answer is given, the calculator 74 adds up the score by 5 points, and the added points are displayed on the score display 78.

When the score reaches (9) points, the decoder 114 that decodes the output of the accumulator 74 generates an output signal a. This output signal a is supplied to the variable divider as a preset signal PR via an OR gate 1161i, and is supplied to an accumulator 118 as a load signal. Therefore, the accumulator 118 is loaded with frequency division ratio correction data corresponding to a predetermined clock frequency increment from the register 120, and this frequency division ratio correction data is preset to the variable division loss.

Therefore, the clock signal φ1 from the variable frequency division loss rises slightly more than before, making it slightly more difficult to guess the next time's note.

As described above for the case of additional points, the lock frequency raising operation is performed in the same way for the case of picture points and for the case of 70 points. That is, in the case of a marked point, the decoder 114 generates an output signal bi, which is supplied to the variable frequency divider as a preset signal PR3 and to the accumulator 118 as a load signal. This friend, accumulator 118
ll1m times of frequency division ratio correction data from 2 to variable frequency division loss
Data corresponding to the multiplied value is preset, and the clock signal φJuku rises by the same amount as the previous rise. In the case of 70 points, the decoder 114 outputs the output signal Ct-
The signals ald, variable division divider 24KFi, and preset signal PR are respectively supplied to the accumulator 118 as a load signal. Therefore, the accumulator 118 presets the variable frequency divider with data corresponding to three times the division ratio correction data in the case of a good point, and the clock signal φB increases in the case of a (material) point. It increases by the same amount as the minute. In other words, as the score increases from 9 points to 70 points, the frequency of the clock signal φB increases little by little.
Along with this, it becomes a little difficult for Otojima as well.

When the score reaches 100 points, the decoder 114 generates an output signal d. This output signal is supplied to the MMD gate 79 via the dd inverter 122, and the start signal 8〒'
While inhibiting the generation of , the signal is supplied to the game over sound data generation circuit 126 via the OR gate 124 . The game over sound data generation circuit 126 is an OR gate 124
Since the game over sound data is supplied to the musical sound forming circuit 16 in accordance with the signal d from the speaker 18, the game over sound is actually produced from the speaker 18. Further, the signal d from the OR gate 124 is sent to the OR gate 6 as a game over signal GO.
The output signal of the OR gate at this time resets the flip-flop 52. Therefore, the counter 32 stops incrementing, and the data acquisition circuit 60 is prohibited from acquiring data.

Further, the signal d from the OR gate 124 is transmitted to the delay circuit 12.

, and the ND gate 130 is conductive due to the output Q='l# of the flip-flop 132. Therefore, the output signal from the delay circuit 128 is
Fan 7 areal data generation circuit 1 via gate 130
34, and in response, the circuit 134 supplies fanf and are data to the tone forming circuit 16. Therefore,
The speaker 18 generates a 7 amp sound, and a 10 amp sound is generated.
Notify that 0 points have been obtained. Oh, delay circuit 128
The output signal causes flip-flop 132 to be reset via delay circuit 136. As a result, one game has ended, and in order to start the next game, it is sufficient to turn on the start switch SW.

The above is the operation when 100 points are scored within the predetermined game time, but if 100 points are not scored within the predetermined game time, the timer circuit η reaches the predetermined game time. At that point, a time-over signal To is generated. This time-over signal TO is sent to the OR gate 12.
4 as the game over signal GO, the same operation as described above regarding the output signal d of the decoder 114 is performed. However, in this case, since the score has not reached 100 points, a fanfare sound is generated if the score is at least 100 points, and a disqualification sound is generated if the score is less than 100 points.

That is, if the score is more than (capital) points, the decoder 11
4 generates an output signal ef, causing flip-flop 132 to be set, so that AND gate 130 becomes conductive. When a predetermined game time is reached, the time-over signal 'rO is supplied to the fanfare data generation circuit 134 via the OR game) 124, the delay circuit 128, and the ND gate 13o, so that the fanfare sound is emitted from the speaker 18. be done.

If the score is less than (capital) points, the output signal e of the decoder 114 is %Qj, so the AND gate 138 becomes conductive due to the output enable=111 of the 7 rive flop. Then, when a predetermined game time is reached, the time-over signal TO is sent to the OR gate 124, the delay circuit 128, and the AND
The disqualified tone data is supplied to the disqualified tone data generation circuit 140 via the gate 138, and in response, the circuit 140 supplies the disqualified tone data to the musical tone forming circuit 16.Therefore, the speaker 18 produces a disqualified tone.

In the above embodiment, the starting pitch and the direction of change of the M sound data MD are determined at random, but these may be set as appropriate using the keyboard prior to the start of the game.

As described above, according to the present invention, players can enjoy the game of hitting moving sounds by pressing keys, thereby naturally developing their sense of pitch and becoming familiar with keyboard instruments. Therefore, the electronic musical instrument according to the present invention is extremely useful for music education for beginners.
