Abstract

PURPOSE:To improve the operability by allowing a musical tone information generating means to generate musical tone information regarding the pitch of a single tone or the pitch of respective constituent tones of a chord specified by the combination state of switches of a pitch specifying means according to the decision result of a decision means. CONSTITUTION:When switches of the pitch specifying means 21 are turned on, for example selectively in combination with the plural switches, the decision means 30 detects the states of the respective switches of the pitch specifying means 21 to discriminate whether the single tone or chord is specified according to the combination state of the switches in the on state. Then a pitch information generating means 30 generates pitch information regarding the pitch of the single tone or the pitch of the respective constituent tones of the chord specified by the combination of the switches of the pitch specifying means 21. Consequently, the plural switches of the pitch specifying means 21 are operated in combination to specify the single tone or chord.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention provides a musical tone specifying device that specifies a single note or a chord, and a musical tone specifying device that specifies a single note or a chord, and a musical tone specifying device that specifies a single note or a chord, and a musical tone specifying device that specifies a single note or a chord, and Alternatively, the present invention relates to an electronic wind instrument having a function of controlling chord generation.

[Conventional technology]

Electronic wind instruments detect the strength of a person's breath operation of blowing into the mouthpiece or lip operation of biting the mouthpiece as an electrical signal using a breath sensor or lip sensor installed in the mouthpiece. It is an electronic musical instrument that can finely control the volume, pitch, etc. of electronically generated musical tones, and can generate musical tones that match the sensibilities of the performer.

In such electronic wind instruments, a group of pitch designation switches consisting of multiple switches are placed in positions where the performer can easily place his or her fingers, and the performer can select the desired pitch with a single operation by combining the ways in which these multiple switches are pressed. One pitch (interval) can be specified.

Further, among the above-mentioned electronic wind instruments, instruments that can play chords have also been devised, and the chords can be specified using a plurality of methods.

For example, you can specify the root note of a chord in advance by operating a group of pitch specification switches, and then program the pitch difference with respect to the root note of the specified chord for all the constituent notes of the other chords. When playing a chord, by operating the pitch specifying switch group to specify the pitch of the root note, the constituent notes of the chord other than the root note can be adjusted based on the programmed pitch difference information. A program method is known in which pitch information is automatically created together with the root note to generate a chord.

In addition, in addition to the above-mentioned pitch specifying switch group, an electronic wind instrument is provided with an octave specifying switch group consisting of a plurality of switches that specify the octave of the musical tone specified by operating the pitch specifying switch group. It is possible to switch between two modes: a normal performance mode in which chords are played, and a chord performance mode in which chords can be played.When the chord performance mode is selected, operation of the pitch specifying switch group There is a mode switching method in which the root note of the chord is set by the octave setting switch, and the chord type is set by operating a group of octave specifying switches.

Furthermore, similar to the electronic wind instrument that can switch between the two modes mentioned above, when the chord performance mode is selected, the type of chord is specified by the number of pitch specification switches that are turned on. be. For example, if only one pitch designation switch is operated, major is designated, and the pitch corresponding to that designated pitch designation switch is set as the root note of the chord, and the pitch designation switch is set to the root note of the chord. If at least two pitch specifying switches of the means are operated simultaneously, a minor chord is specified, and then each pitch specified by the simultaneously operated pitch specifying switches is connected to a continuous pitch relationship. If there is a continuous pitch relationship, either the highest pitch or the lowest pitch of the specified pitches is taken as the root of the chord, and discontinuous pitches are determined. If it is a pitch relationship, the other of the specified pitches that is different from the one pitch is set as the root note of the chord, and the chord is created depending on the number of pitch designation switches that are operated at the same time. There was an electronic wind instrument that specified chords using a one-finger method that selected and specified the root note of a chord from among multiple pitches specified by the type.

[Problem to be solved by the invention]

However, when setting chords using the program method as described above, there is a switch for inputting the pitch difference, a display device for displaying the input data during programming, and a device for storing the input pitch difference information. It is necessary to provide additional memory, which complicates the manufacturing process and increases costs due to the increased number of parts.
The programming operation is also complicated and there is a problem that the operability is poor. Furthermore, if you turn off the power, the set pitch difference information will be deleted.
It was inconvenient to have to reprogram it. For this reason, if the memory is back-amplified, a device for memory backup must be provided, which increases the cost, and the mounting space of the electronic wind instrument itself is small, so an external device for boosting the memory bank must be installed. However, it is inconvenient to carry, and there is also the problem that the cord connecting the memory backup device and the main body of the electronic wind instrument interferes with performance.

In addition, in the case of the above mode switching method, fingering operations for the pitch specification switch group to specify the root note of the chord and fingering operations for the octave specification switch group to specify the chord type are performed. However, in the case of natural wind instruments, unlike the fingering operations on the keyboard of keyboard instruments, the fingers of both the right and left hands are used to press the multiple keys to open and close the tube holes. A single pitch is specified by a combination of . Therefore, fingering operations for specifying chords using the mode switching method described above require fingering operations for the octave specifying switch group in addition to the pitch specifying switch group, and are clearly different from fingering operations for natural wind instruments. This poses a problem in that it gives a sense of discomfort to performers who are accustomed to playing natural wind instruments. Therefore, it is preferable for the performer to perform not only a single note designation operation but also a chord designation fingering operation by combining fingering operations for a plurality of pitch designation switches using both hands.

Furthermore, in specifying chords using the one-finger method described above, the specification of the root note of the chord is very different from the fingering operation on natural wind instruments, and the type of chord also depends on the number of pitch specifying switches that are pressed with the finger. The disadvantage was that it was extremely difficult for users to learn the fingering operations.

An object of the present invention is to enable single notes and chords to be specified by fingering operations similar to those of a recorder, which are easy to operate, and to easily perform single notes and chords without the need for mode switching operations. To provide a musical tone specifying device and an electronic wind instrument which are extremely easy to operate and can be switched and played in real time.

[Means to solve the problem]

The means of the present invention are as follows.

First, the means of the musical tone specifying device according to claim 1 is as follows.

The pitch specifying means can specify a single note or a chord by, for example, a combination operation of a plurality of switches such as selectively turning on only a predetermined switch from among a plurality of switches. It is placed in a position where it is easy for the player to place his or her fingers on it.

The determining means determines whether a single note pitch designation operation or a chord pitch designation operation has been performed based on the state of each switch of the pitch designation means.

The musical tone information creation means generates musical tone information relating to the pitch of a single note or the pitch of each component note of a chord, which is specified by the combination state of the plurality of switches of the pitch specifying means, based on the discrimination result by the discrimination means. Create.

The discrimination means and the musical tone information creation means are comprised of, for example, a microprocessor, and are arranged inside the tubular body.

Next, the means of the musical tone specifying device according to claim 2 is as follows.

The pitch specifying means is divided into a first pitch specifying means and a second pitch specifying means, and by operating the first pitch specifying means, one of the root notes of the chord or the type of the chord is selected. One chord information is specified, and the other chord information, which is different from the one chord information, is specified by operating the second pitch specifying means.

Further, the musical tone information creating means determines the type of chord specified by the operation of the first pitch specifying means and the second pitch specifying means and information regarding the root note of the chord. Create pitch information for each constituent note of the chord.

Further, the means of the musical tone/effect determining device according to claim 3 is as follows.

The pitch specifying means is divided into a first pitch specifying means for specifying the root of a chord, and a second pitch specifying means for specifying the type of chord.

Further, the musical tone information creation means is configured to generate the specified chord based on the root of the chord specified by the first pitch specifying means and the type of chord specified by the second pitch specifying means. Create pitch information for each constituent sound.

Further, the means of the pitch specifying device according to claim 4 is as follows.

The pitch specifying means includes first pitch specifying means for specifying the root note of the chord, similar to the pitch specifying means according to claim 3 described above;
and a second pitch specifying means for specifying the type of chord, and when the second pitch specifying means is not operated, the first pitch specifying means is divided into two pitch specifying means for specifying the type of chord. It is possible to specify the pitch of each musical tone in a range of at least one octave.

Further, when the second pitch specifying means is not operated and a musical tone of a predetermined pitch is specified by operating only the first pitch specifying means, the musical tone information creating means is configured to generate the first tone. Pitch information related to the pitch specified by the combination of the switches of the pitch specifying means is created.

Further, the means of an electronic wind instrument using the musical tone specifying device according to claim 5 is as follows.

First, there is provided a musical tone specifying device having a pitch specifying means, a discriminating means, and a musical tone information creating means according to the second aspect.

Controls the generation of single notes or chords determined by

[For production]

The operation of the tone specifying device according to the first aspect is as follows.

When a combination of a plurality of switches is performed on the plurality of switches of the pitch specifying means, such as selecting a switch to be turned on, the discriminating means determines the state M of each switch of the pitch specifying means (for example, on/off). For example, based on the combination of switches that are on, it is determined whether a single note designation operation or a chord designation operation has been performed. Next, the pitch information creation means generates pitch information related to the pitch of a single note or the pitch of each component note of a chord, which is specified by the combination of the plurality of switches of the pitch specification means, based on the discrimination result by the discrimination means. Create.

With the above operation, you can only select a single note by simply operating the combination of multiple switches of the pitch specifying means, without having to provide a mode changeover switch to select between the two modes of specifying a single note or a mode specifying a chord. It is now possible to specify chords.

Next, the operation of the musical tone specifying device according to the second aspect is as follows.

When specifying a chord, the pitch specifying means is virtually divided into a first pitch specifying means and a second pitch specifying means,
The root note of the chord is specified by operating the first pitch specifying means, and the type of chord is specified by operating the second pitch specifying means. Conversely, the type of chord may be specified by the first pitch specifying means, and the root note of the chord may be specified by the second pitch specifying means.

In this way, the designation of the root note and the designation of the type of chord are performed separately by the operation of the first pitch designation means and the operation of the second pitch designation means. For example, each switch of the high specification means is a switch group similar to a recorder (
key group) array, “C”, rDJ, “E”, rFJ
A group of switches that specify each pitch (rcJ to "F") (
key group) as the first pitch specifying means, rGJ, rAJ, rB
It is also possible to use a switch group (key group) for specifying each pitch of J (rGJ to "B") as the second pitch specifying means. When the pitch designation means is configured as described above, for example, if the root note of the chord is one of the pitches rcJ to rFJ, the recorder is connected to the first pitch designation means. The root note of the chord is specified by performing fingering operations similar to the above, and the type of chord is specified using the second pitch specifying means, while the root note of the chord is rGJ to rB.
If the pitch is one of J, specify the root note of the chord by performing fingering operations similar to those on a recorder on the second pitch specifying means, and then specify the root note of the chord on the second pitch specifying means. It is also possible to specify the type of chord by finger operation.

As described above, when the root note of a chord and the type of chord are specified by operating the first pitch specifying means and the second pitch specifying means, the discriminating means performs an operation for specifying the pitch of the chord. The pitch information creating means operates the pitch specifying means based on the status of each switch of the first pitch specifying means and the second pitch specifying means. The root note and chord type of the specified chord are detected, and pitch information of each constituent note of the specified chord is created.

Through the above operation, the root note of the chord is specified by performing a fingering operation similar to that of a recorder on the first pitch specifying means or the second pitch specifying means, and the pitch specifying means specifies the chord. Since it is possible to specify the type of chord by using the other pitch specifying means different from the pitch specifying means, it is possible to easily specify the chord by, for example, a fingering operation similar to that of a recorder.

Next, the operation of the musical tone specifying device according to claim 3 is as follows.

specifying the root note of the chord by operating the first pitch specifying means;
When the type of chord is specified by operating the second pitch specifying means, the discriminating means determines that the chord pitch specifying operation has been performed, and the musical tone information creating means operates the first pitch specifying means. Pitch information of each constituent note of the specified chord is created based on the root note of the chord specified by the above and the type of chord specified by the operation of the second pitch specifying means.

In this way, unlike the musical tone specifying device according to claim 2, the root note of a chord can be specified by operating the first pitch specifying means, and the type of chord can be set by operating the second pitch specifying means. Since this is fixed, it is easy to learn the designation of the root note of a chord, and if the type of chord is set according to the combination of the switch states of the second pitch designation means, the second When the number of switches in the pitch specifying means is n, it is possible to specify a maximum of 2'' types of chords, and even with a small number of switches, it is possible to specify many types of chords.

Furthermore, the operation of the musical tone specifying device according to claim 4 is as follows.

When the second pitch specifying means is not operated and the combinations of the switches of the first specifying means are operated, the pitch information creating means is configured according to the combination of the switches of the first pitch specifying means. Musical tone information relating to a single note of a predetermined pitch is created.

Therefore, not only can a chord be specified by operating the first pitch specifying means and the second pitch specifying means as in the above-mentioned musical tone specifying device according to claim 3, but also the chord can be specified by operating the first pitch specifying means and the second pitch specifying means. It is also possible to specify a single note by operating a combination of switches.

Furthermore, the operation of the electronic wind instrument according to claim 5 is as follows.

When at least one of the breath operation of blowing into the mouthpiece or the lip operation of biting the mouthpiece is performed,
The strength of at least one of the operations is sensed by the sensor means, and the musical tone control means generates a single note or chord specified by the musical tone specifying device according to claim 1 based on the sense information sensed by the sensor means. Take control.

Therefore, a fingering operation is performed on the pitch specifying means of the pitch specifying device according to claim 1, and at least one of the breath operation and lip operation is performed on the mouthpiece of the instrument body. This makes it possible to play single notes or chords.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First Embodiment) Construction Implementation Figure 1 is an external view of an electronic wind instrument 1 according to a first embodiment of the present invention.

As shown in the figure, the electronic wind instrument 1 has the shape of a wind instrument consisting of a tubular section 2 and a mouthpiece section 3, and on the front surface of the tubular section 2 are seven pitch specifying switches 21a to 21.
A pitch designation switch group 21 for specifying a single note or a chord consisting of g is on the rear surface of the tubular section 2, and a sharp (#) setting switch 22 on the rear surface of the tubular section 2 raises all pitches by a semitone. On the right side, there are provided an octave setting switch 23 that raises the tone by one octave when pressed, and a tone change switch 24 that sequentially changes the tone between saxophone, trumpet, synth reed, oboe, clarinet, and flute each time it is operated. ing. In addition, a speaker 70-
2 is provided.

Further, a breath sensor 4 is provided inside the main body in the vicinity of the connection position between the mouthpiece 3 and the tubular cylinder part 2 to detect the strength (amount of breath) of breath blown into the mouthpiece 3 . Further, inside the tubular portion 15, although not particularly shown, a control circuit for generating musical tones, which will be described later, is provided.

Next, FIGS. 2(a) and 2(b) are partially enlarged views of the front of the tubular portion 2, and diagrams showing an example of fingering operations of the pitch designating switch group 21, respectively.

Pitch specification switch group 212 to pitch specification switch group 21g
As shown in Figure (a), there is a “C” similar to a recorder.
” (C) to “B” (B) are assigned to each note.

FIG. 3 is a diagram showing an operation method for specifying a pitch by fingering operations on each pitch setting switch of the pitch specifying switch group 21. In the figure, the pitch designation switch for performing fingering operations is indicated by a black circle.

As shown in the figure, the pitch of a single note is specified by fingering operations similar to those on a recorder. In other words, if you press only the pitch designation switch group 21g, the pitch of "B4° (B of 4 octaves) will be designated, and if you press the pitch designation switch group 21f and the pitch designation switch group 21g at the same time, rA4
” (4 octave A) pitch is specified. From now on, by fingering operations similar to those on a recorder, "C4" to "G4"
Each pitch is specified. Furthermore, the pitch of "C5" is designated by a finger pressing operation (fingering operation) only on the pitch designation switch group 21f.

On the other hand, to specify a chord, as shown in FIG. 2(b), the first pitch specification switch group 211 (pitch specification switch group 218,
21f, 21g), and a second pitch designation switch group 212 (pitch designation switch group 21a) for performing fingering operations with the right hand.
, 21b, 21C.

21d), and the root note of the chord is specified by fingering operations on one pitch specifying switch group, and the type of chord is specified by fingering operations on the other pitch specifying switch group.

In the first embodiment, a major chord (Major C
hord), Minor Chord
d) Three types of chords can be specified: ``C4'', ``D4'', and 7th chord.
In the case of specifying a chord with "F4" as the root note, specify the root note of the chord by fingering operations on the second pitch specifying switch group 212, and specifying the root note of the chord by fingering operations on the first pitch specifying switch group 211. Specify the type of chord.

At this time, the fingering operations for the second pitch designation switch group 212 are the same as when specifying a single note, and each pitch designation switch r21eJ, r
By performing fingering operations on 21fJ and r21gJ, you can create "major chord" and "minor chord" respectively.
, "seventh chord" is specified.

On the other hand, in the case of specifying a chord whose root note is "G4", "A4", "B4", or "C3", the root note of the chord is set to the The type of chord is designated by fingering operations on the pitch designation switch group 212 of 2. In this case as well, the fingering operations for the first pitch specifying switch group 211 for specifying the root note of the chord are exactly the same as when specifying a single note, and the pitch specifying switch for the second pitch specifying switch group 21 is the same as when specifying a single note. r21aJ, r21bJ
, r21cJ to create "major chord,""minorchord," and "r21cJ," respectively.
7th chord” is specified.

In this way, by performing fingering operations similar to those on a recorder on one of the first pitch specifying switch group 211 and the second pitch specifying switch group 212, "C4" is produced. Any one of the other pitch specifying switch groups that can specify the root note of a chord over a range of one octave or more from "C5" and is different from the pitch specifying switch group that specified the root note of the above chord. One pitch designation switch group 21
By performing fingering operations on the chord, you can specify the type of chord: ``major chord,'' ``minor chord,'' or ``seventh chord.'' For this reason, the fingering operations for specifying the root note of a chord are almost the same as on a recorder, making it easy to learn, and the type of chord can be specified using only one pitch specifying switch that corresponds to the desired chord. Since all that is required is to perform fingering operations, the fingering operations are easy and easy to learn.

Next, FIG. 4 shows the determination of the pitch of a single note or the chord of each chord of "major chord", "minor chord", and "seventh chord" specified by fingering operations on the above-mentioned pitch specifying switch group. FIG. 2 is a system configuration diagram showing a circuit configuration of a control section that controls the generation of the determined single note or chord.

The CPU 30 is a central processing unit consisting of, for example, a microprocessor, and includes a ROM (not shown).
It operates according to the program stored in its own memory.

The CPU (central processing unit) 30 includes a pitch designation switch group 21, an octave switch 23, and a tone selection switch 24.
The status (on/off state) of each switch, , and sharp (#) setting switch 22, is read at predetermined time intervals using a timer interrupt (timer interrupt) applied from a timer not particularly shown, and the read pitch is read. Determine the pitch of the single note specified by the pitch specification switch group 21 (when a single note is specified) or the pitch of the root of a chord and the type of chord (when a chord is specified) from the status information of the specification switch group 21 . Further, from the read status information of the octave switch 23, the octave specified by the octave switch 23, and from the status information of the tone color changeover switch 24, the tone color specified by the operation of the tone changeover switch 24 is determined. When the designation of the pitch changes, pitch information for generating a musical tone of the newly designated pitch is output to the musical tone generating circuit 40. Furthermore, the CPU 30 outputs timbre information to the musical tone generating circuit 40 for generating a musical tone with the designated tone.

As mentioned above, pitches from "C4" to "C6" can be specified by fingering operations on the pitch specifying switch group 21, and pitches from "C4" to "C6" can be specified by operating the pitch specifying switch group 21 by operating the octave switch 23. Since it is possible to specify one octave higher than the pitch specified by the pitch, by operating the pitch specifying switch group 21 and the octave switch 23, "C4" can be specified.
” to “Ch” can be specified. CPU30
performs processing by converting each specified pitch in the range from "C4J" to "C6" into pitch information (internal code value) as shown in FIG.

In addition, the strength (or amount) of the breath when performing a breath operation to blow into the mouthpiece 3 of the electronic wind instrument body is as follows:
The sensing information sensed by the breath sensor 4 is applied to the voltage detection circuit 50 . Then, the voltage detection circuit 50 converts the sensed information into an analog voltage (sense signal) corresponding to the sensed information and applies it to an A/D converter (analog/digital converter) 60. A
The /D converter 60 converts the applied analog voltage into predetermined bits of digital data (breath data) and sends it to the CPU 30.
Output to. The CPU 30 generates a key-on signal to start generating musical tones based on breath data input via the A/D converter 60, a key-off signal to stop generating musical tones, or a musical tone generated from the musical tone generating circuit 40. Volume information, etc. specifying the volume level of is created and outputted to the musical sound generation circuit 40.

In addition, the CPU 30 uses code flags, KENAME, 0CTBFXNEWKEY, and 0LDKE, which will be explained in detail later.

CHORD I, CHORD 2, CHORD3, N
It has various built-in registers such as EWCODE, 0LDCODE, etc., BRATH register, R register, etc.

The R register is a register that stores the status of each of the pitch designation switches 21a to 21g of the pitch designation switch group 21 read by the CPU 30 in bit units, and is a 7-bit register as shown in FIG. The structure is as follows. Each status of the pitch designation switch 21a to pitch designation switch 21g of the pitch designation switch group 21 is set to bit 1 of the R register, respectively, as shown in the figure.
(LSB) to bit 7 (MSB) are stored in each bit. The value of the bit is 1'' when the switch is on and 0 when the switch is off.

As shown in FIG. 7, the single note conversion table 31 includes an R register value storage area 31-1 in which the contents (values) of the R register corresponding to each single note designation are stored, and the R register value storage area 31-1. This is a table consisting of a single note pitch information storage area 322 in which single note pitch information (internal code value) corresponding to the contents of each R register in the RA register is stored.
It is stored in M (Random Access Memory) or ROM (Read Only Memory).

When the CPU 30 reads the status of each pitch designation switch in the pitch designation switch group 21, the CPU 30 stores the status information of each pitch designation switch in the R register.
Using the contents of the R register as a key, the R register value storage area 31-1 in the single note conversion table 31 is searched to determine whether the pitch of a single note has been specified.

For example, pitch designation switch 2 of pitch designation switch group 21
When all the switches 1a to pitch designation switch 21g are turned on and the pitch of "C4" is specified, all bits of the R register become "1", but the contents of the R register are used as key data. By searching the single note conversion table 31 as 6, pitch information (internal code value) of "C4" corresponding to the content in which all bits of the R register are "1" is obtained.
0" (decimal value) is read out, and the CPU 30 determines that a single note of pitch "C4" has been designated by the fingering operation on the pitch designation switch group 21.

Further, as shown in FIG. 8, the chord conversion table 32 includes R register values in which the contents of the R register corresponding to each chord designation of "major chord", "minor chord", and "seventh chord" are stored. A chord structure storing pitch information (internal code value) of each constituent note of the chord corresponding to the contents of each R register stored in the storage area 32-1 and the R register value storage area 32-1. Sound storage area 32-2
This table is stored in a memory such as ROM or RAM.

The CPU 30 searches the R register value storage area 32-1 using the value of the R register storing the latest status of each pitch designation switch in the pitch designation switch group 21 as a key,
It is determined whether a chord is specified by the fingering operation on the pitch specification switch group 21, that is, whether a value matching the contents of the R register is stored in the R register value storage area 32-1, If the contents of the R register that match the value of the R register are stored, it is determined that a chord has been specified, and the pitch information of each constituent note of the chord corresponding to the contents of the R register is stored. Read from area 32, -2.

In the figure, each constituent note of the chord stored in the chord constituent note storage area 32-2 is indicated by a pitch symbol such as "C4" or "E44," but in reality, these notes are Pitch information (internal code value) shown in FIG. 5 corresponding to the high symbol is stored.

The musical sound generation circuit 40 has an analog sound source or a digital sound source such as an FM sound source or a PCM sound source, and can simultaneously generate a plurality of musical sounds with different pitches by time-sharing control, etc. Based on the pitch information, timbre information, volume information, etc. of each constituent note, the pitch information of each constituent note of a single note or chord of the specified pitch is set to the tone color, volume, etc. corresponding to the above tone information, volume information. It is generated based on the musical tone characteristics and is added to the musical tone output section 70. Musical sound output section 7
0 starts generating a single note of the specified pitch or each constituent note of the specified chord by adding key-on information, and stops generating musical tones of the above-mentioned single note or chord by adding key-off information from the CPU 30. do.

The musical tone output section 70 includes an amplifier circuit 70-1 and a speaker 70.
-2, and outputs a single note or chord added from the musical tone generating circuit 40 as sound to the outside.

(Description of Operation of First Embodiment) Next, the operation of the first embodiment having the above configuration will be described with reference to the flowcharts shown in FIGS. 9A and 9B to FIG. 11.

Figures 9A and 9B by Kenshojo Samurai Natsuki show control processing for single note generation and chord generation that is performed by the CPU 30 every time a timer included (timer interrupt) is added at a predetermined period from a timer (not shown). It is a flow chart explaining.

The CPU 30 first checks the status of each switch 21a to 21g of the pitch designation switch group 21
The status of each switch is stored in the R register shown in FIG. (SAI).

As a result of the above operation, the status of the switches 21a to 21g is set to the first bit (LSB) of the R register, respectively.
) to the seventh bit (MSB).

Next, the R register value storage area 31- in the single note conversion table 31 shown in FIG. 7 is set using the R register value as key data.
1 (5A2), and determines whether a single note has been specified (SA3).

If a single note has been specified, the pitch information corresponding to the value of the R register is stored in the single note pitch information storage area 31-2.
The read pitch information is read from the buffer KE.
Store in NAME (SA4).

Next, read the status of the octave switch 23 (5A5) determine whether the octave switch 23 is on or not (5A6), and if the octave switch 23 is on, store the buffer 0CTBF "12" (5AT), If it is off, "0" is stored in the buffer 0CTBF (SA8).

Then, buffer KENAME and buffer 0CTBF are added, and the addition result is stored in buffer NEWKEY (SA9).

Furthermore, the status of the sharp setting switch 22 is read out (5A10), and it is determined whether the sharp setting switch 22 is turned on (5AII). If the sharp setting switch 22 is turned on, the buffer NE is read out.
Add "1" to WKEY (SA12).

Through the above operation, the pitch information (internal code value) of the single note specified by the operation of the pitch specifying switch group 21, octave switch 23, and sharp setting switch 22 is stored in the buffer NEWKEY. For example, when fingering operations are performed on the pitch designation switch 21f and the pitch designation switch 21g, bits 6 and 7 (MSB) of the R register are set to "1", and the other bits are set to "1". It becomes “0”. Then, the single note conversion table 31 shown in FIG. 7 is searched using the value of the R register as a key.
"69", which is the pitch information corresponding to "4", is the buffer KE.
Stored in NAME (SA1 to 5A4). Furthermore, since the octave switch 23 is on, "12" is stored in the buffer 0CTBF, and then the buffer KENAME and the buffer 0CTBF are added,
The value “81” obtained by the addition is stored in the buffer NE.
It is stored in WKEY (SA5 to 5A9). Furthermore, since the sharp setting switch is on, the buffer N
The value of EWKEY is added “1” and becomes “・82” (
SAIL~5A12). As a result, pitch information corresponding to the pitches of "A," is stored in the buffers NIF and WKEY (see FIG. 5). That is, as shown in FIG. 3, by performing a fingering operation corresponding to the pitch of "A4" on the pitch specifying switch group 21, and further operating the octave switch 23 and the sharp setting switch 22,
The pitch of rAs"J, which is one octave higher and a semitone higher than "4", is specified.

After performing the above processing 5A12 or determination processing 5AII
If it is determined that the sharp setting switch 22 is not on, it is then determined whether the values stored in the buffers NEWKF,Y and the values stored in the buffer 0LDKEY are equal (SA13).

Buffer 0LDKEY stores previously specified pitch information as described later, and pitch specification switch group 2
1. If the operations of the octave switch 23 and the sharp setting switch 22 are the same both last time and this time, the values of the buffer NEWKEY and the values of the buffer 0LDKEY will be the same. Therefore, it is determined whether the pitch designation has changed by determining whether the value of the buffer NEWKEY and the value of the buffer 0LDKEY are equal.

If it is determined in step 5A13 that the pitch designation is different from the previous one, the buffer NEWKEYO value is stored in the buffer 0LDKEY (SA14). Next, buffer NEWKE
The pitch information stored in Y is written to the buffer KDATA (SA15), and it is determined whether the sounding flag is on (SA16).

The sound generation flag is a flag that stores whether or not a musical sound is currently being generated from the musical sound generation circuit 40, and is set to "1" (on) if a musical sound is being generated, and "0" if a musical sound is not being generated.
” (off) is memorized.

In step 5A16 above, if the generating flag is on, a key-off signal instructing the tone generation circuit 40 to stop generating musical tones is output (5A17), and the generating flag is set to "0" (off).
(SA18).

Then, the tone pitch information stored in the buffer KDATA is output to the musical tone generation circuit 40.

On the other hand, if the sounding flag is not on in 5A16 above,
Immediately, the pitch information stored in the buffer KDATA is output to the musical tone generation circuit 40 (SA19).

When the pitch designation changes as a result of the above operation, if a musical tone is currently being generated from the musical tone generating circuit 40, the musical tone generating circuit 40
The musical tone generation from 0 is stopped, the pitch information of the newly specified single note is output to the musical tone generation circuit 40, and the generating flag is reset from "1" (on) to "0" (off). Ru.

Furthermore, when the pitch designation changes, if no musical tone is generated from the musical tone generation circuit 40, the newly specified pitch information is immediately output to the musical tone generation circuit 40.

Further, if it is determined in step 5A13 that the pitch designation has not changed, the process immediately ends.

On the other hand, if the pitch of a single note has not been specified in SA3, it is then determined whether or not a chord has been specified by the fingering operation of the pitch specification switch group 21, and the chord is specified. If so, chord generation processing 5A2 generates a chord.
Do 0.

10A and 10B are detailed operational flowcharts of the chord generation process 5A20 performed by the CPU 30.

First, the CPU 30 searches the R register value storage area 32-1 in the code conversion table 32 shown in FIG. 8 using the value of the R register as a key. -1, that is, whether a chord has been specified (
SB2). Then, if a predetermined chord is specified, R
After storing the register value in the buffer KENAME (S
B3), read the status of the octave switch 23; 5B4), and determine whether the octave switch 23 is on (SB5).

If the octave switch 23 is on, "128" is stored in the buffer 0CTBF (5B6), and if it is off, "0" is stored in the buffer 0CTBF (SB7).
. Next, buffer KENAME and buffer 0CTBF
and stores the addition result in the buffer NEWCODH (SB8).

Through the above operation, the values (hereinafter referred to as chord information) corresponding to each chord specified by the operations of the pitch specification switch group 21 and the octave switch 23 are stored in the buffer NEWCOD.
It is stored in E. For example, the first pitch specifying switch group 2
11 pitch designation switches 21a to 21d and the pitch designation switch group 21e of the second pitch designation switch group 212, and select "C4" without turning on the octave switch 23. If you specify a C major chord as the root note (see Figure 3), buffer NE
If "31" is stored in WCODH and you operate the pitch designation switch group 21 in the same way as above, and then turn on the octave switch 23 to designate a C major chord with "C1" as the root note, the buffer “159” (=“31”+“128”) is stored in NEWCODE.

In this way, if chords of the same type have different root notes, different values are stored in the buffer NEWCODE.

Also, when the octave switch 23 is turned on,
Since "128", which is a value larger than the maximum value of the R register, is added to the R register, when the octave switch 23 is on, the same value as other types of codes will be stored in the buffer NEWCODE. In other words, if the code type is different, the buffer NEWCODE
Different values (chord information) are stored in the buffer NEWCODE, and even if the chords are of the same type but have different root notes, different chord information is stored in the buffer NEWCODE. That is, the buffer NEWCOD obtained as a result of the addition in process SB8
The value of H (chord information) is a different value for each chord type, and even if the chord is the same, it will be a different value if the root note is different.

Subsequently, it is determined whether the code information stored in the buffer NEWCODE and the code information stored in the buffer 0LDCODE are equal (SB9).

The buffer 0LDCODE stores the chord information specified last time as described later, and if the chord specified by the operation of the pitch specifying switch group 21 and the octave switch 23 is the same as the previous time and this time, the buffer NEWC is stored.
The values of the code information stored in ODE and the buffer 0LDCODH become equal. Therefore, the buffer NEW
By determining whether the value of CODE and the value of buffer 0LDCODH are equal, it is determined whether the chord designation has been changed.

If it is determined in SB9 above that the chord designation has been changed, buffer NEWCODE is set to buffer 0LDCODE.
Store the code information stored in E (SBIO)
.

Then, the chord conversion table 32 shown in FIG. 8 is searched using the value of the R register stored in the buffer KENAME as key data, and the root, third, and third notes constituting the chord corresponding to the value of the R register are searched. The pitch information of the 5 notes (in addition, the 7th note in the case of a 7th chord) is read from the code conversion table 32, and each buffer CHORDO~
Write to CHORD2 (CWORD3) (SBII
).

Through the above operation, the pitch information of each component note of the chord specified by the fingering operation on the pitch specification switch group 21 and the operation of the octave switch 23 is transferred to the buffer CHORDO~
Stored in CHORD2 (CHORD3).

For example, by performing fingering operations on all the pitch specifying switches in the first pitch specifying switch group 211 and the pitch specifying switch 21e in the second pitch specifying switch group 212,
” If you specify a C major chord with the root note (
(see Figure 3), the value of the R register stored in the buffer KENAME is roolllllJ (binary representation)
, and the above r00111 from the code conversion table 32
"C4", "B4", and "G" of the C major chord with "C4" as the root corresponding to the contents of the R register of 11J.
4" is read out, and the buffer CH
It is stored in ORDO-CHORD2 (see FIG. 8).

Similarly, fingering operations are performed on the pitch designation switch group 21a of the first pitch designation switch group 211 and the pitch designation switch group 21g of the second pitch designation switch group 212.
When specifying a B major chord with the root note "B4" (see Figure 3), the value of the R register stored in the buffer KENAME is rl OOOOOOIJ, which is calculated from the chord conversion table 32 shown in Figure 8. rlooo above
"B4" of the B major chord with the root note "B4" corresponding to the contents of the R register of "001", rps "J,
The pitch information of each component tone of rFs"J is read out, and each read pitch information is stored in the buffers CHORDO to CHO.
Stored in RD2.

Also, in the case of other chords, the first pitch specifying switch group 211 and the second pitch specifying switch group 212
The pitch information of each constituent note of the chord specified by the fingering operation on each pitch specifying switch is read out from the chord conversion table 32 based on the contents of the corresponding R register,
Buffer CHORDO ~ CHORD2 (CHORD3
).

Following 5BII above, the value of buffer 0CTBF is 0”
5B12), buffer 0CTBF
If the value of is not “0”, the buffer CHORD O~C
Add “12” to the value of HORD2 (CHORD3) (SB13).

As a result of the above operation, when the octave switch 23 is turned on, each constituent note of the chord specified by the fingering operation on the first pitch specifying switch group 211 and the second pitch specifying switch group 212 is One octave higher.

Further, it is determined whether or not the sound generation flag is on ("1") (5B14), and if the sound generation flag is on, a key-off signal is output to the musical tone generation circuit 40 (SB15). Next, set the sounding flag to off (aO'') 5B1
6), Buff-, CHORDO-CHORD2 (C
The pitch information of the constituent tones of the chord stored in WORD3) is output to the musical tone generation circuit 40 (SB17).

On the other hand, if the sounding flag is turned off in step 5B14, the process in step 5B17 is immediately performed.

Through the above operation, if a musical tone is being generated from the musical tone generating circuit 40 when the chord designation is changed, the musical tone generating circuit 40 stops generating musical tones, and the pitch of each component note of the newly specified chord is changed. While outputting the information to the musical sound generation circuit 40,
The generating flag is reset to off (O”).If the musical tone generation circuit 40 does not generate musical tones when the chord designation is changed, the sound of each constituent note of the newly specified chord is immediately generated. The high information is output to the musical tone generation circuit 40.

The single note or chord specified by the operation of the pitch specifying switch group 21 and the octave switch 23 as described above and set in the musical tone generating circuit 40 under the control of the CPU 30 requires the breath operation on the mouthpiece 3 to be performed with a force greater than a predetermined force. By doing so, the musical tone generation circuit 40 generates the musical tone.

FIG. 11 is an operation flowchart illustrating the musical tone generation control process performed by the CPU 30 when a breath operation is performed.

When a timer included (timer interrupt) is added from the timer at a predetermined period, the CPU 30 reads the breath data corresponding to the strength of the breath operation via the A/D converter 60, and reads the breath data, which is not particularly illustrated. No BP
Write to ATH register (SCI).

Next, it is determined whether the value of the breath data stored in the BPATH register is greater than or equal to the threshold Th for starting generation of the key-on signal (5C2), and if it is greater than or equal to the threshold Th, the sounding flag continues to be turned on. (“1”) (SC3).

Then, if the sound generation flag is not on, that is, if the musical tone generation circuit 40 is not currently generating a musical tone, the musical tone generation circuit 40 outputs a key-on signal and initial information instructing the volume, etc. at the time of starting generation.5C4) , sets the sounding flag to on (“1”) (SC5). The initial information is set based on, for example, the amount of change in the breath data per unit time after the breath data exceeds the threshold Th.

Through the above operations, when the key-on signal is applied, the musical tone generating circuit 40 starts generating a chord or a single note based on the pitch information of each constituent note of the chord or the pitch information of a single note added from the CPU 30.

In addition, if the sounding flag is not on (“1”) in SC3 above, after-sales information such as pitch information that specifies the volume of the chord (or single note) being emitted is sent based on the size of the breath data. Create and output to musical tone generation circuit 40 (SC6)
.

Through the above operation, when the performer performs a breath operation, the volume of the chord or single note emitted from the musical tone section output section 70 changes depending on the strength of the breath operation.

On the other hand, if the value of the breath data is smaller than the key-on threshold Th at SC2, the sounding flag is turned on (“1”).
5C7), and if the sound generation flag is on (“1”), a key-off signal is output to the musical tone generation circuit 40 (SC8).

Then, set the sounding flag to off (“0”) (
SC9).

As a result of the above operation, if the value of the breath data becomes smaller than the predetermined key-on threshold Th while a chord or single note is being generated, a key-off signal is output to the musical tone generation circuit 40,
As a result, the musical tone generation circuit 40 stops generating chords or single tones, and the musical tone output section 70 stops emitting musical tones.

Note that the key-off darkness value may not be set to the same value as the key-on darkness value as in the first embodiment, but may be set to a value slightly smaller than the key-on darkness value.

(Second Embodiment) Next, an electronic wind instrument according to a second embodiment of the present invention will be described.

The external appearance and system configuration of the second embodiment are shown in FIGS. 1 and 4, respectively, and are the same as those of the first embodiment described above.

However, in the second embodiment, the fingering operation method for the pitch designation switch group 21 in single note specification and chord specification is different from the first embodiment. Conversion table 31 (hereinafter,
The contents of the single note conversion table 31') and the chord conversion table 32 (hereinafter referred to as the chord conversion table 32° to distinguish it from the first embodiment) are the same as those of the first embodiment. This is different from the example.

FIG. 12 is a diagram illustrating a fingering operation method for the pitch designation switch group 21 when specifying a single note and a chord in the second embodiment.

As shown in the figure, single note designation is performed by pitch designation switch groups 21b, 21c, and 2 in the first pitch designation switch group 211.
This is performed by fingering operations on the three switches 1d. For example, when specifying the pitch of "C4", perform fingering operations on all pitch specifying switches 21a to 21d, and when specifying the pitch of "B4", Fingering operations are performed only on the pitch designation switch 21c. Hereinafter, by performing fingering operations on the first pitch specifying switch group 12 as shown in FIG.
Each pitch of "D4", "E4", "G4", and "A4" can be specified. In this way, in the second embodiment, each pitch in the one-octave range from "C4" to "B4" can be specified.

In addition, in the case of chord specification, the first pitch specification switch group 2
11, specify the root note of the chord by performing the same fingering operations as when specifying a single note as described above, and then perform fingering operations on the second pitch specifying switch group 212 to select "major chord J,"
Specify the type of each chord: "minor chord" and "seventh chord". That is, as shown in FIG. 12, a "major chord" is specified by performing a fingering operation on the pitch designation switch group 21e, and by performing a fingering operation on the pitch designation switch groups 21f and 21g.
A "minor chord" and a "seventh chord" are specified respectively.

In this way, in the second embodiment, the pitch specification of a single note and the pitch specification of the root note of a chord can be performed by completely similar fingering operations on the first pitch specification switch group 211, The fingering operations for specifying the root note of a chord are very easy to remember. Furthermore, the fingering operations for specifying each chord such as "major chord,""minorchord," and "seventh chord" do not change depending on the root note of the chord as in the first embodiment, but specify pitch. switch group 21c,
21f and 21g correspond fixedly to the "major chord,""minorchord," and "seventh chord," respectively, making it extremely easy to remember.

(LSB) ~ Bit 4 is bit string data corresponding to each pitch from "C4" to "B4" according to the fingering operation on the first pitch designation switch group 211 when specifying a single note as shown in FIG. is stored. For example, to specify a single note of "F4", fingering operations are performed on the pitch specifying switch group 21b and the pitch specifying switch group 21d of the first pitch specifying switch group 211, so the value of the R register is rololooo.
o”. Similarly, to specify the pitch corresponding to "B4", only the fingering operation is performed on the pitch specifying switch group 21c of the first pitch specifying switch group 211, so the value of the R register becomes "roolooooooo". . As described above, in response to the fingering operation on the first pitch specifying switch group 211 stored in the R register value storage 31-1', the value of each R register corresponds to the corresponding fingering operation. The pitch information storage area 31- for which the pitch information corresponding to the value is a single note
