The sounding unit 2 amplifies the musical sound signal input from the sound source unit 8 described later, and outputs it as a musical sound from the built-in speaker.
However, in the present embodiment, the sounding unit 2 is built in the electronic wind instrument 100, but the sounding unit 2 is not limited to the built-in type and is not connected to the external output port (not shown) of the electronic wind instrument 100. It may be a type.

The CPU 5 functions as a control unit that controls each part of the electronic wind instrument 100, reads a program designated from the ROM 6 and expands it into the RAM 7, and executes various processes in cooperation with the expanded program.

It should be noted that the functions and the like of each sensor described below are explanations of the main functions and the like, and may be provided with other functions.

The breath sensor 10 includes a pressure sensor, and the breath sensor 10 can detect the breath value such as the breath volume and the breath pressure of the performer blown from the opening 3aa on the base end side of the mouthpiece body 3a. Will be done.
The breath value detected by the breath sensor 10 is used by the CPU 5 to set the note on / off of the musical tone, the volume of the musical tone, and the like.

Further, the voice sensor 11 includes a microphone, and the voice sensor 11 detects the voice (growl waveform) for the performer's growl performance.

The presence or absence of contact of the tongue with the position of (tunging detection) is performed.
The presence or absence of contact of the tongue detected by the tongue sensor 12 is used by the CPU 5 to set the note on / off of the musical tone, and the presence or absence of contact of the tongue and the detection state of the breath value of the breath sensor 10 are used. It is used to set the pitch according to both states.

The lip sensor 13 includes a pressure sensor or a capacitance sensor provided with a plurality of detection units 13s from the base end side (tip side) to the tip side (heel side) of the lead portion 3c, and has a lip. It functions as a pressure sensor unit 13a and a lip position sensor unit 13b.

It serves as a lip pressure sensor unit 13a for detecting the contact strength of the lip.

When the contact of the lip is detected by the plurality of detection units 13s, the lip position is obtained by the CPU 5 obtaining the contact center position based on the output from the lip sensor 13.

For example, when the lip sensor 13 has a pressure sensor, the contact strength (lip pressure) of the lip and the lip position are detected based on the change in pressure detected by the pressure sensor.

When the lip sensor 13 has a capacitance sensor, the lip contact strength (lip pressure) and the lip position are detected based on the change in capacitance detected by the capacitance sensor.

Then, the detection result of the contact strength (lip pressure) of the lip by the lip sensor 13 as the lip pressure sensor unit 13a and the detection result of the lip position by the lip sensor 13 as the lip position sensor unit 13b are used for vibrato performance and subtone performance.

Based on the state), the subtone performance is detected and the processing corresponding to the subtone is performed.

The electronic wind instrument 100 can be played by performing the same operation as when the performer plays a normal saxophone, but it is difficult for a beginner to perform the same performance operation as an expert. Therefore, in the electronic wind instrument 100 of the present embodiment, the performance can be performed mainly only by the breathing operation of the performer, which will be specifically described below.

As mentioned earlier, the ROM 6 stores song data, so-called MIDI data.
The song data includes data for making accompaniment by an instrument other than the saxophone electronic wind instrument 100 (hereinafter, also referred to as this instrument) sound using the sounding unit 2 of this instrument, and for automatically playing this instrument. Data etc. are included.

Therefore, by using this song data, it is possible for the performer to practice according to the level of the performer by setting a part of the performance part as an automatic performance instead of playing the whole performance. A specific description will be given with reference to the flowchart shown in FIG.

FIG. 4 is a flowchart showing the main routine of processing, FIG. 5 is a flowchart of expression practice which is a subroutine in the main routine of FIG. 4, and FIG. 6 is continuous data which is a subroutine in the expression practice of FIG. It is a flowchart of the part which creates the correction data value of the data value of.

The performer selects a performance mode such as "Expression practice", "Vibrato performance", "Growl performance", "Subtone performance" and "Other processing (for example, only accompaniment)". When the performance start operation is performed after setting whether to play the song, the processing of the main routine shown in FIG. 4 is started.

In step S1, the CPU 5 determines whether or not the performer has selected "expression practice".
Then, when the CPU 5 determines that the performer has selected "expression practice" (step S1: Yes), the CPU 5 proceeds to step S11, and the CPU 5 executes the processing of the flowchart shown in FIG. 5, which will be described later.
On the other hand, when the CPU 5 determines that the performer has not selected "expression practice" (step S1: No), the CPU 5 proceeds to step S2.

In step S2, the CPU 5 determines whether or not the performer has selected "Leave the vibrato performance", and if it is determined that "Leave the vibrato performance" is selected (step S2: Yes), the process proceeds to step S21. If it is determined that "expression practice" is not selected (step S2: No), the process proceeds to step S3.

In step S21, the CPU 5 disables the function of the lip sensor 13 as the lip pressure sensor unit 13a, and proceeds to step S22.
That is, the CPU 5 sets the process of step S21 so that the lip pressure is not reflected in the sounding process, and proceeds to step S22.

In step S22, the CPU 5 executes a process corresponding to "Leave the vibrato performance", and the process ends, that is, when the performance ends, the entire process ends.
Specifically, the CPU 5 causes the sound source unit 8 to perform a process of automatically playing a part (for example, an accompaniment) of a musical instrument other than the main musical instrument based on the song data of the song selected by the performer, and produces a sound. The unit 2 produces a sound corresponding to the automatic performance by the input from the sound source unit 8.

In step S22, the CPU 5 also executes a process of reading and acquiring the song data (MIDI data) of the selected song from the ROM 6 into, for example, the RAM 7 functioning as a work area so that the above-mentioned automatic performance can be performed.
However, the acquisition destination need not be limited to ROM 6, for example, the song data (MIDI data) can be acquired from a USB memory, from an external terminal (device other than the electronic wind instrument 100), or acquired via the Internet. Therefore, it is not always necessary that the song data is stored in the ROM 6 in advance.

Further, the CPU 5 causes the sound source unit 8 to perform an automatic performance process based on the music data of the part corresponding to the vibrato in the performance part of the musical instrument, and the sound source unit 2 automatically plays by the input from the sound source unit 8. The vibrato sound will be produced according to.
The processing of the portion corresponding to the vibrato may be a processing in which a correction that reflects the breath value described later with reference to FIGS. 5 and 6 is performed.

Further, the CPU 5 causes the sound source unit 8 to perform processing according to the operation (performance) of the performer except for the part corresponding to the vibrato in the performance part of the musical instrument, and the sound source unit 2 inputs from the sound source unit 8. Will produce the sound according to the player's operation.

In step S3, the CPU 5 determines whether or not the performer has selected "Growl performance entrusted", and if it is determined that "Growl performance entrusted" is selected (step S3: Yes), the process proceeds to step S31, and " If it is determined that "Growl performance is left to you" is not selected (step S3: No), the process proceeds to step S4.

In step S31, the CPU 5 disables the voice sensor 11 and proceeds to step S32.
That is, the CPU 5 sets the process of step S31 so that the voice of the performer is not reflected in the sounding process, and proceeds to step S32.

In step S32, the CPU 5 executes a process corresponding to "Growl performance entrusted", and when the process ends, that is, when the performance ends, the entire process ends.

Specifically, the CPU 5 causes the sound source unit 8 to perform a process of automatically playing a part (for example, an accompaniment) of a musical instrument other than the main musical instrument based on the song data of the song selected by the performer, and produces a sound. The unit 2 produces a sound corresponding to the automatic performance by the input from the sound source unit 8.
In step S32, the CPU 5 also executes a process of reading and acquiring the song data (MIDI data) of the selected song from the ROM 6 into, for example, the RAM 7 functioning as a work area so that the above-mentioned automatic performance can be performed.

Further, the CPU 5 causes the sound source unit 8 to perform a process of automatically playing the part corresponding to the growl in the performance part of the musical instrument based on the music data, and the sound source unit 2 automatically plays by the input from the sound source unit 8. The sound of the growl will be produced according to.
It should be noted that the processing of the portion corresponding to the growl may be a processing in which a correction that reflects the breath value described later with reference to FIGS. 5 and 6 is performed.

Further, the CPU 5 causes the sound source unit 8 to perform processing according to the operation (performance) of the performer except for the part corresponding to the growl in the performance part of the musical instrument, and the sound source unit 2 inputs from the sound source unit 8. Will produce the sound according to the player's operation.

In step S4, the CPU 5 determines whether or not the performer has selected "subtone performance entrusted", and if it is determined that "subtone performance entrusted" is selected (step S4: Yes), the process proceeds to step S41. If it is determined that "Leave the subtone performance" is not selected (step S4: No), the process proceeds to step S5.

In step S41, the CPU 5 disables the function of the lip sensor 13 as the lip position sensor unit 13b, and proceeds to step S42.
That is, the CPU 5 sets the lip position not to be reflected in the sounding process as the process of step S41, and proceeds to step S42.

In step S42, the CPU 5 executes a process corresponding to "Leave the subtone performance", and when the process ends, that is, when the performance ends, the entire process ends.

Specifically, the CPU 5 causes the sound source unit 8 to perform a process of automatically playing a part (for example, an accompaniment) of a musical instrument other than the main musical instrument based on the song data of the song selected by the performer, and produces a sound. The unit 2 produces a sound corresponding to the automatic performance by the input from the sound source unit 8.
In step S42, the CPU 5 also executes a process of reading and acquiring the song data (MIDI data) of the selected song from the ROM 6 into, for example, the RAM 7 functioning as a work area so that the above-mentioned automatic performance can be performed.

Further, the CPU 5 causes the sound source unit 8 to automatically perform the part corresponding to the subtone of the performance part of the musical instrument based on the music data, and the sound source unit 2 automatically plays the part corresponding to the input from the sound source unit 8. The subtone sound will be produced according to.
It should be noted that the processing of the portion corresponding to the subtone may be a processing in which the correction that reflects the breath value described later with reference to FIGS. 5 and 6 is performed.

Further, the CPU 5 causes the sound source unit 8 to perform processing according to the player's operation (performance) except for the part corresponding to the subtone in the performance part of the musical instrument, and the sound source unit 2 inputs from the sound source unit 8. Will produce the sound according to the player's operation.

In step S5, the CPU 5 executes other processing, and when the processing is completed, the entire processing is completed.
As other processing, for example, processing such as automatic performance of parts other than the performance part of the musical instrument can be considered.

In this case, the CPU 5 causes the sound source unit 8 to automatically perform a part (for example, an accompaniment) of an instrument other than the main instrument based on the music data of the song selected by the performer, and the sound source unit 2 Will produce a sound corresponding to the automatic performance by the input from the sound source unit 8.
In step S5, the CPU 5 also executes a process of reading and acquiring the song data (MIDI data) of the selected song from the ROM 6 into, for example, the RAM 7 functioning as a work area so that the above-mentioned automatic performance can be performed.

Further, the CPU 5 causes the sound source unit 8 to perform a process according to the operation (performance) of the performer, and the sound source unit 2 produces a sound according to the operation of the performer by the input from the sound source unit 8.

On the other hand, when the determination in step S1 is Yes and the process proceeds to step S11, the CPU 5 executes the processing of the flowchart of the expression practice of FIG.
The expression practice of the present embodiment is a performance mode in which the performer can perform by breathing in, and the performer does not need to operate the performer 1 to perform the performance. In a certain part, the CPU 5 causes the sound source unit 8 to perform processing according to song data (MIDI data).

Further, in the expression practice, the performance accompanying the breathing operation is performed based on the performance data value (hereinafter, also simply referred to as the data value) acquired from the song data (MIDI data) corresponding to the case where the performer is a beginner. (For example, vibrato performance, growl performance, and subtone performance) are automatically performed according to the playing method.
However, it is not a completely automatic performance, but from the basic breath value and the breath sensor 10 acquired by the CPU 5 from the song data (MIDI data) according to the state of the performer's breathing operation (breath value acquired from the breath sensor 10). Compare with the acquired breath values, and based on those basic breath values and breath values, the expressive power of the performer's breathing operation (breathing) will be reflected in the vibrato performance, growl performance, subtone performance, etc. In addition, the performance data value (data value) is corrected, and the output process of outputting the sound wave shape data corresponding to the corrected correction data value to the sound source unit 8 is performed, which will be specifically described below.

In step T1, the CPU 5 executes a process of reading and acquiring song data (MIDI data) selected by the performer from the ROM 6 into, for example, the RAM 7 functioning as a work area.

In step T2, the CPU 5 causes the sound source unit 8 to automatically play a part (for example, accompaniment) of another musical instrument other than the main musical instrument based on the acquired song data (MIDI data), and the sound source unit 2 Start the pronunciation of accompaniment corresponding to other musical instruments.
The part related to this accompaniment is not described in the following flow, but the accompaniment corresponding to it is pronounced according to the progress of the performance of the instrument described below.

In step T3, the CPU 5 determines whether or not the breath value acquired from the breath sensor 10 is equal to or greater than a threshold value given in advance.
If the breath value is equal to or greater than the threshold value, the process proceeds to step T4 assuming that the performer has started playing, and if the breath value is less than the threshold value, the process proceeds to step T10 assuming that the performer has started playing.

As will be described later, step T10 determines whether the end instruction to end the performance or the song data is finished, and if neither of them (step T10: No), the process proceeds to step T3 again.

Therefore, if the process proceeds from step T2 to step T3 and the determination in step T3 is No, either the performer's end instruction operation or the start of breathing into the performer's mouthpiece portion 3 accompanying the start of the performance is performed. You will enter a monitoring loop, waiting for this to happen.

In step T4, based on the breath value and the note-on data of the song data (MIDI), the CPU 5 causes the sound source unit 8 to perform the corresponding processing, and the sound source unit 8 pronounces the sound of the instrument to the sound source unit 2. Let me.
Then, when the sound is generated by this note-on, it is subsequently based on the continuous data of the song data (MIDI data), which is the control data that continuously changes with time from this note-on to the next note-on. However, in the present embodiment, the data value of the continuous data is sequentially converted to the breath value by performing the loop processing in which steps T5 to T8 are repeated as described below. The correction is made based on the above, and the expressive power according to the state of the player's breathing operation (breath value acquired from the breath sensor 10) is reflected.

In step T5, the CPU 5 executes the process shown in the flowchart of FIG.

In step U1, the CPU 5 determines whether or not the breath value acquired from the breath sensor 10 is equal to or greater than the basic breath value provided in the song data, and determines that the breath value is equal to or greater than the basic breath value (step U1: Yes). ) Then, the process proceeds to step U2, and when it is determined that the breath value is less than the basic breath value (step U1: No), the process proceeds to step U3.

In step U2, for example, when the performance data value (data value) of the continuous data of the song data is a data value according to the vibrato playing method, the CPU 5 is a correction value for deepening the vibrato depth with respect to the data value. Is calculated.
Further, when the data value is a data value according to the growl playing method, the CPU 5 calculates a correction value for increasing the synthesis ratio of the growl waveform.
Further, when the data value is a data value according to the subtone playing method, the CPU 5 calculates a correction value for increasing the synthesis ratio of the subtone waveform.

Specifically, the ROM 6 or the like is provided with a conversion table or a function for calculating the correction value, and the CPU 5 obtains the correction value according to the conversion table or the function based on the basic breath value and the breath value.

For example, the CPU 5 simply describes an index such as the difference between the basic breath value and the breath value and how much the breath value is larger than the basic breath value (hereinafter, the index represented by the difference,%, etc. is simply referred to as "difference". In some cases), the correction value of how much correction should be made to the data value of the continuous data of the song data is obtained according to the conversion table or the function.

In the present embodiment, as a conversion table or function for obtaining the correction value, when the difference between the basic breath value and the breath value is small, the correction value is set to be small, and when the difference is larger than a certain level, the correction value is increased at once. I am trying to be.
That is, the correction for the data value of the song data is a non-linear correction based on the conversion table or the function.

This is a musical tone when the changes in vibrato, glow, and subtone increase linearly with the same amount of increase as the difference between the basic breath value and the breath value increases in a region where there is no difference above a certain level. When the difference between the basic breath value and the breath value is small, the correction value is set to be small because it makes the person feel uncomfortable.
That is, the correction value is also increased according to the increase in the difference between the basic breath value and the breath value, but the slope of the increase is made small.

On the other hand, when the breath value is sufficiently large (when there is a difference of a certain amount or more), it is more natural that the vibrato, glow, and subtone are also pronounced to explode, so the difference is larger than a certain amount correspondingly. In that case, the correction value is increased at once.

In step U3, for example, when the performance data value (data value) of the continuous data of the song data is a data value according to the vibrato playing method, the CPU 5 calculates a correction value for shallowing the vibrato depth.
Further, when the data value is a data value according to the growl playing method, the CPU 5 calculates a correction value for reducing the synthesis ratio of the growl waveform.
Further, when the data value is a data value according to the subtone playing method, the CPU 5 calculates a correction value for reducing the synthesis ratio of the subtone waveform.

Specifically, the calculation of the correction value performed in step U3 is also performed by the CPU 5 according to the conversion table or the function for calculating the correction value in the same manner as in step U2, and the reason is explained in step U2. In the same way as in, the non-linear correction is used so that the sound does not become unnatural.

In step U4, the CPU 5 creates a correction data value obtained by correcting the data value of the continuous data of the song data based on the correction value calculated in step U2 or step U3.

In the case of vibrato, the data value corresponding to the vibrato of the song data (for example, the data value of bend data or the data value of modulation data) is corrected based on the correction value.
That is, when the breath value is larger than the basic breath value, the CPU 5 acquires the corrected data value in which the depth of the vibrato is deepened with respect to the data value corresponding to the vibrato, and the breath value is less than the basic breath value. In this case, the corrected data value obtained by correcting the data value corresponding to the vibrato to make the depth of the vibrato shallow is acquired.

If the breath value matches the basic breath value, the correction value is set so that the correction data value is the data value itself corresponding to the vibrato of the song data.
For example, when the correction data value is multiplied by the data value corresponding to the vibrato of the song data, the correction value may be set to 1, and when the correction value is added, the correction value is 0. You can do it.

If it is a growl, the data value corresponding to the composite ratio of the growl waveform of the song data is corrected based on the correction value.
That is, when the breath value is larger than the basic breath value, the CPU 5 acquires the corrected data value obtained by correcting the data value corresponding to the composite ratio of the glow waveform to increase the composite ratio, and the breath value is the basic breath value. If it is less than, the corrected data value obtained by correcting the data value corresponding to the combined ratio of the glow waveform to reduce the combined ratio is acquired.
If the breath value matches the basic breath value, the correction value is set so that the correction data value is the data value itself corresponding to the composite ratio of the glow waveform of the song data, as in the case of vibrato. Will be done.

If it is a subtone, the data value corresponding to the composition ratio of the subtone waveform of the song data is corrected based on the correction value.
That is, when the breath value is larger than the basic breath value, the CPU 5 acquires the corrected data value obtained by correcting the data value corresponding to the composite ratio of the subtone waveform to increase the composite ratio, and the breath value is the basic breath value. If it is less than, the corrected data value obtained by correcting the data value corresponding to the composite ratio of the subtone waveform to reduce the composite ratio is acquired.
If the breath value matches the basic breath value, the correction value is set so that the correction data value is the data value itself corresponding to the composition ratio of the subtone waveform of the song data, as in the case of vibrato. Will be done.

Then, when the correction data value as described above is created in step U4, the processing of the flowchart shown in FIG. 6 is completed, and the process returns to the processing of the flowchart of FIG.

In step T6, the CPU 5 causes the sound source unit 8 to perform processing based on the correction data value, and causes the sound source unit 2 to pronounce the pronunciation based on the correction data value by the input from the sound source unit 8.

The growl waveform for growl performance may be a growl waveform generated based on the voice of the performer acquired by the voice sensor 11, and the data (specified pitch) held in the song data (MIDI data) may be used. It may be a growl waveform generated based on the data for adjusting the mix ratio of mixing the growl data with the sound form data of.
Similarly, the subtone waveform may be a subtone waveform generated based on the data (data for adjusting the output amount of the subtone) stored in the music data (MIDI data).

As described above, the CPU 5 corrects the data value of the song data (MIDI data) based on the basic breath value of the song data (MIDI data) given in advance and the breath value acquired from the breath sensor 10. By performing the correction data value acquisition process for acquiring the corrected data value and the sounding process for causing the sounding unit 2 to make a sound based on the corrected data value, the expressive power associated with the performer's breathing operation (breathing) is reflected. It will be a performance.

In step T7, the CPU 5 determines whether or not the song data (MIDI data) is note-on timing (timing for operating the controller 1 to change the sound), and determines that it is the note-on timing (step T7: Yes), the process returns to step T4, and the process of step T4 described above is executed again.
On the other hand, if it is determined that the CPU 5 is not the note-on timing (step T7: No), the process proceeds to step T8.

In step T8, the CPU 5 determines whether or not the breath value is less than the threshold value, and if it is determined that the breath value is not less than the threshold value (step T8: No), the CPU 5 returns to step T5 and returns to step T5. The process is executed again.

In other words, since the process of correcting the data value of the continuous data is performed again, the sound itself, which is pronounced so as to continuously change with time, is accompanied by a change according to the breathing operation of the performer. It reflects the expressiveness of the performer.

On the other hand, when the CPU 5 determines that the breath value is less than the threshold value (step T8: Yes), the CPU 5 proceeds to step T9.

In step T9, in order to stop the sounding due to the player's breath not being blown into the mouthpiece unit 3, the CPU 5 causes the sound source unit 8 to perform the corresponding processing, and the sound source unit 8 sends the corresponding process. The sound source 2 mutes the sound of this instrument by input.

In step T10, as mentioned earlier, the CPU 5 determines whether the performance end instruction or song data end by the performer, and determines that neither the end instruction nor the song data end (step T10: No). Since it was the timing of breathing that the breath value became less than the threshold value in step T8, the process returns to step T3 again, and the state of the monitoring loop for monitoring the start of the next breathing by the performer is entered.

On the other hand, the CPU 5 returns to the process of the flowchart of FIG. 4 when it is determined to be either the end instruction or the end of the song data (step T10: Yes), and the entire process is completed.

As described above, in the electronic wind instrument 100 of the present embodiment, in the practice of expressiveness by the performer's breathing operation (breathing), some performances (for example, vibrato performance, growl performance and subtone performance) are automatically performed. Even if it is done, it is not a fully automatic performance, but reflects the expressive power of the performer's breathing operation (breathing), so it is suitable for learning the expressive power.

In addition, because the expressive power of the performer is reflected in this way, depending on how it is played, it is possible to perform not just as a model, but as a unique and longing musician, and there are various ways for the performer to enjoy it. It has become something that can be done.
