Abstract

PURPOSE:To execute a natural and smooth musical performance by constituting the title wind instrument so that when a finger moving operation of plural sound pitch setting switch means has been varied, new sound pitch information corresponding to the variation of its finger moving operation is outputted to a musical tone generating means, after a prescribed delay time has elapsed from the time point of its variation. CONSTITUTION:When a finger moving operation of plural sound pitch setting switch means 2 has been varied when a musical performance is being executed by a breath operation, new sound pitch information corresponding to the variation of its finger moving operation is outputted to a musical tone generating means 7, after a prescribed delay time has elapsed from the time point of its variation. Accordingly, even if the finger moving operation of plural sound pitch setting switch means 2 by a performer is executed in an hourly variance state, and as a result, a moment in which a correct finger moving operation cannot be executed simultaneously is generated, it does not occur that a musical tone of an unnecessary sound pitch is generated in its moment. In such a way, a natural and smooth musical performance can be executed in a state that sounding of a musical tone is continued.

Description

DETAILED DESCRIPTION OF THE INVENTION [Fields of application of the present invention] JJ relates to an electronic wind instrument equipped with a breath sensor that generates a desired musical tone in response to a player's wind performance.

[Prior Art and Problems to be Solved by the Invention] Some conventional electronic wind instruments equipped with a breath sensor are capable of variably controlling musical sound parameters such as the volume and quality of the musical sound generated according to the strength of the blowing input. The present applicant has also proposed this type of electronic wind instrument in U.S. Pat. No. 61-120958 and other documents.

By the way, in such a conventional electronic wind instrument, in order to set the pitch of the musical sound to be generated, the pitch setting means having a plurality of pitch setting switches simultaneously switches one selected combination of the plurality of pitch setting switches. By performing a fingering operation to turn it on or off, the pitch setting means outputs pitch information and the musical tone generation circuit generates a musical tone of a desired pitch.

Therefore, if a performer wants to change the pitch of a musical note during a performance, the performer must turn on or off multiple pitch setting switches accurately at the same time using fingering operations with multiple fingers. If you want to change the high by a semitone, you will need to use the opposite fingering (cross fingering), which involves adding a new lever or key operation to the original fingering, and even those with considerable experience will be able to use the correct fingering. There is a problem in that there are moments when this is not possible, and at those transitional moments, an unnecessary musical tone with an incorrect pitch is emitted.

Recently, as a way to solve these conventional problems,
An electronic wind instrument described in Japanese Patent Publication No. 59-42315 is known. According to this electronic wind instrument, in order to prevent musical tones of unnecessary pitches from being emitted during octave shifting, an output muting circuit is provided that mutes musical tones during octave shifting.

This may cause the musical tone output to be interrupted temporarily during performance.
The problem is that it is not possible to perform naturally and smoothly.

In addition, there is a large difference in fingering operation techniques between beginners and experienced players, and there is a problem that cannot be solved by Ritsu.

Furthermore, in the case of this type of electronic wind instrument, the octave selection switch is operated to change the pitch set by the pitch setting switch to raise or lower the pitch in octave units. However, since this kind of octave switching operation is performed with the thumb, it is particularly difficult to operate compared to changing the pitch using the pitch setting switch, and it is difficult to change the octave at the same time as the fingering operation of the pitch setting switch. It is difficult to operate, and there is a problem in that during the operation of switching from a specified pitch to a pitch a predetermined octave above or below, a musical tone of an unnecessary pitch is emitted.

[Purpose of the Invention] This invention was made to solve the above-mentioned conventional problems, and in order to change the RF height of a musical tone during a performance, fingering operations of a plurality of pitch setting switches are performed. An object of the present invention is to provide an electronic wind instrument that does not emit musical tones with unnecessary pitches even if the fingering operations vary and an incorrect fingering operation momentarily occurs. do. Another object of the present invention is to provide an electronic wind instrument that can emit musical tones with a delay in pitch that corresponds to changes in fingering operations, depending on the degree of fingering technique of the performer. .

Furthermore, the electronic wind instrument is capable of preventing musical tones of unnecessary pitches from being emitted even if there is a timing lag between the switching operation of the octave selection switch and the fingering operation of the pitch setting switch. The purpose is to provide

Yet again. To provide an electronic wind instrument capable of setting a delay time suitable for the switching operation of an octave changeover switch, which is more difficult to change than the fingering operation of a pitch setting switch.

[Summary of the Invention] This invention has been made to achieve such an object, and the invention according to claim 1 is characterized in that the fingering operations of the plurality of pitch setting switch means in the pitch setting means are changed. If, after a predetermined delay time has elapsed from the point of change,
The invention according to claim 2 is characterized in that new pitch information corresponding to the change in the fingering operation is outputted to the musical tone generating means. The main point is that the delay time variable setting means further includes a variable delay time setting means that can be set variably.

Further, the invention according to claim 3 provides that when the fingering operations of the plurality of pitch setting switch means in the pitch setting means change, the fingering operation is changed after a predetermined first delay time has elapsed from the time of the change. New pitch information corresponding to the change in fingering operation is output to the musical tone generating means, and when the switching operation of the octave switching means changes, a predetermined second delay time is set from the time of the change. The key point is that after the period of time has elapsed, new pitch information corresponding to the change in the switching operation is outputted from the pitch information output control means to the musical sound generation means.

Further, in the invention as claimed in claim 4, the first delay time for the fingering operation of the pitch setting switch means and the second delay time for the switching operation of the octave switching means are independently set by the delay time variable setting means. The main point is that it can be set variably.

Furthermore, the invention set forth in claim 5 is such that the second delay time for the switching operation of the octave switching means is set longer than the first delay time for the fingering operation of the pitch setting switch means. The main point is what you did.

[Embodiment] An embodiment of the electronic wind instrument according to the present invention will be described below with reference to one drawing.

First Embodiment> First, a first embodiment, which is an embodiment of an electronic wind instrument according to the present invention (invention according to claim 1 or 2), will be described.

Structure of the first embodiment FIGS. 1A and 1B are a front view and a left side view showing the appearance of the first embodiment.
01a, a breath sensor l that detects the strength or amount of breath of the blow player, a pitch setting switch group 2 (pitch setting switches 2-1 to 2-8), a tone/effect changeover switch group 3. A speaker 4, a TrLri, a switch 5, etc. are provided.

FIG. 2 is an overall circuit configuration diagram showing the electric circuit within the wind instrument main body 101 of FIG. 1, and the same reference numerals as in FIG. 1 indicate those having the same functions.

CPU is a central processing unit consisting of a microprocessor
Reference numeral 6 controls the electric circuit of the entire wind instrument, as well as controlling the generation and muting of musical tones produced by the musical tone generating circuit 7.The functions of this CPU 6 will be described below, and the overall circuit configuration will be explained. .

The first function of the CPU 6 is to receive pitch information output from the pitch setting switch group 2 constituting the pitch setting means and to send it to the musical tone generation circuit 7. Second
The second function is the breath sensor l, which is a breath sensor means.
The breath information from is first converted into a voltage value by the voltage conversion circuit 8, and roughly converted into digital breath information by the A/D converter 9. This is to output to the musical tone generation circuit 7 as start instruction information, musical tone control information such as the volume and tone of musical tones. C
The third function of the PU6 is to receive the pitch information from the pitch setting switch group 2 and the tone effect effect information selected by the specified operation of the tone/effect changeover switch group 3, and to output each of these pieces of information. Accordingly, a musical tone of a specific pitch with a specific tone color and effect is outputted to the musical sound output device 10, and the musical tone is emitted as an acoustic output from this musical sound output device 10.

The fourth unit 1t of the CPU 6 is to realize pitch information output control means, which is the key point of the configuration of this first embodiment, and for this purpose, the fourth unit 1t of the CPU 6 is configured to output pitch information from a timer 11 provided in this CPUB. This is to control the musical tone generation circuit 7 based on the instructions. That is, when the on/off state of the pitch setting switch group 2 is changed by fingering operation in order to change the pitch of a musical tone to be generated during a performance, pitch information is immediately output to the musical tone generation circuit 7. Instead, if there is a change in the specified operation of at least one switch in the pitch setting switch group 2, the timer 11 will set the pitch setting switch after a predetermined delay time has elapsed from the time of the change. Then, new pitch information corresponding to the changed fingering operation is output to the musical tone generation circuit 7. The operation of the CPU 6 that realizes this pitch information output control means will be further described later.

FIG. 3 shows the pitch setting switch 2 of the wind instrument in this embodiment.
This is a diagram showing examples of fingering operations 1 to 2-8. The black circles indicate the switches that are being suppressed (switches in the on state).
A white circle indicates a switch that has not been suppressed (a switch that is in an OFF state). The fingering operation chart corresponding to the pitch of each note CJ, AJ, and C5 on the musical staff shown in Fig. 3-1 in Fig. 3 is shown in Fig. 3-2 in Fig. 3. Here, in order to change the pitch to playing a musical tone with a pitch of As while playing a musical tone with a pitch of C4, use the pitch setting switches 2-1 to 2-2 corresponding to the pitch of C(. From the state where all 8 are turned on, pitch setting switches 2-1 to 2
It is necessary to turn off all the fingers of the 5 trees that are turning on -5 at the same time.

In conventional electronic wind instruments, there was a problem that if there were variations in the timing of the off operation of the five fingers, a musical sound with an unnecessary pitch would be emitted at the moment of the incorrect fingering operation. . Also, while playing a musical tone of A4 pitch,
In order to change the pitch to playing a musical tone with pitch C5, a new tone must be changed for the playing condition of pitch A4, where pitch setting switches 2-6 to 2-8 are turned on. It is necessary to simultaneously turn on all the high setting switches 2-1 to 2-5 with five fingers, and also turn off the pitch setting switch 2-8 (located on the front side of the electronic wind instrument body 101) at the same time. Yes, if the OFF operation of pitch setting switch 2-8 is too quick compared to the ON operation of the other five fingers, the musical pitch of A3, which is one octave higher than the pitch of A4, will be played at that moment. There was a problem in that the sound was emitted unnecessarily.

In this invention, in order to prevent such inconvenient musical sounds from being emitted, when the fingering operation state of the pitch setting switch group 2 is changed, the timer 11 is operated from the time of the change, and the instruction from the timer 11 is activated. Based on the predetermined delay time (at least the time until the fingering operation stabilizes in the correct state)
The configuration is such that the output of the pitch information from the pitch setting switch group 2 to the musical tone generating circuit 7 is delayed. Therefore, the musical tone generation start instruction information is sent from the CPU 6 to the musical tone generation circuit 7 with a delay of the delay time, and as a result,
A musical tone with a changed desired pitch is generated without producing any undesirable musical tone.

In addition, a timer value setting operator 1 is used to arbitrarily set the length of the delay time in accordance with the fingering operation skill level of the performer.
1a, and the length of the delay time can be arbitrarily set variably by operating this operator 11a.

Next, referring to FIGS. 4 and 5, we will explain the operation of the electronic wind instrument of the first embodiment, particularly the CPU 6 and timer 11 that realize the pitch information output control means that is a feature of this embodiment. We will describe the operation of.

FIG. 4 is a scanning flowchart of the pitch setting switch group 2, which is a subroutine that repeatedly operates at predetermined intervals with respect to the main routine (not shown) of the CPU 6. First, step 4-
In step 1, the on/off operation status of the pitch setting switch r+2 is scanned and read, and by this scanning, the read pitch information is stored in the pitch information buffer NEWH.
In the next step 4-2, it is determined whether the current pitch information is the same as the contents of the previous pitch information buffer γ0LDB in which the previously read pitch information was stored. If it is determined to be YES, there is no change in the pitch setting switch group 2 for changing the pitch, so the process returns to the main routine; if it is determined to be No, step 4- Proceed to step 3, and check whether the change flag in the timer 11 in the CPU 5, which counts the elapsed time after the pitch setting switch group 2 is changed, is set to 1, that is, whether the timer 11 is counting. to decide. If it is determined as YES, the timer 11 has started counting, and in step 4-4, the changed current pitch information stored previously in preparation for the next determination is replaced with the previous pitch information. After moving to the buffer, return to the main routine. If the determination is No, it means that the timer 11 has not started counting, and the change flag of the timer 11 is set to 1 in step 4-5, and the count value of the timer 11 is set in step 4-6. After setting the timer 11 and starting counting, the process returns to the main routine.

In this way, this scan flow scans to see if there is a change in the on/off operation status of pitch setting switch group 2 during @19, and when a change is detected, the count of timer 11 is is started, and the musical tone generation circuit 7 passes from the pitch setting switch group 2 to the CPU 6.
This system is designed to count the elapsed delay time to delay the pitch information output to the 2000 by a predetermined time, so that even if the state of the pitch setting switch group 2 changes, the changed pitch information will not be displayed immediately. The key point of this embodiment is that the signal is not outputted to the musical tone generating circuit 7.

Next, FIG. 5 is a flowchart of the pitch change process,
This flow causes the main routine to be timer-interrupted. First, in step 5-1, it is determined whether the value of digital breath information based on the breath information detected by the breath sensor 6 due to the blowing exceeds the level of a predetermined key-on setting value that should instruct the start of musical tone generation. If it is determined as YES, the key is on, that is, a musical tone is being generated, and in step 5-2, the musical tone generating circuit uses the data in the current pitch information buffer NEWB or the previous pitch information buffer 0LDB as pitch information. 7 to generate a musical tone of a pitch corresponding to the on/off state of the pitch setting switch group 2 based on the pitch information, that is, the current or previous fingering operation.

Next, in step 5-3, the change flag of timer 11 is set to O.
Then, in step 5-4, the count of the timer 11 is stopped, and the next pitch setting switch group 2 is reset.
After preparing for the state change, the program returns to the main routine and ends the operation.

Also, if it is determined NO in step 5-1, this means that the value of the digital breath information has not reached the predetermined key-on setting value, and the key-off is not yet the time to instruct the start of musical tone generation. , proceed to step 5-3,
The following operations are performed in the same way as when the key is on, and the process returns to the main routine.

In this way, this flow includes processing for changing the pitch of the currently sounding musical note to a new pitch after the change, based on the pitch information whose settings have been changed by fingering operations. , a timer process is performed for counting the elapse of a predetermined delay time set in the timer buffer TIMBF and controlling the timer intertwined start time of this flow.

Effects of the Embodiment As mentioned above, in the electronic wind instrument according to the first embodiment, the pitch setting switch group 2 (2-1 to 2-8) is
Even when the fingering operation is changed, the pitch information corresponding to the changed state is not immediately outputted to the musical sound generation circuit 7, and based on the instruction to start sound generation by the timer 11, a predetermined delay time (at least the correct pitch information is output). Only after the time required to complete a stable fingering operation has elapsed, the musical tone of the pitch corresponding to the changed fingering operation is emitted from the digit generation circuit 7. If the finger operations are in a transient state where they are not stable in a predetermined operation state, that is, the timings of operations of the plurality of pitch setting switches 2-1 to 2-8 by multiple fingers do not match each other and the fingerings are performed with a time difference. Even when operated, musical tones with unnecessary pitches will not be produced.
In addition, unlike conventional models, there is no silencing circuit, so the silencing circuit does not temporarily interrupt the sound emission of musical tones. This has the effect of allowing you to change the sound and perform with natural pronunciation.

Furthermore, the timer 11 is coupled with a timer value setting operator 11a that allows the performer to arbitrarily set a delay time for delaying the output of pitch information according to his or her playing skill. The delay time can be set according to the fingering operation level, making it very effective and easier to play.

Second Embodiment Next, a second embodiment of the electronic wind instrument according to the present invention (invention according to claim 3 or 4) will be described.

Figures 6A and 6B are a left side view and a rear view showing the appearance of the second embodiment, and the first side view and back view are the views of the appearance of the first embodiment.
Components with the same reference numerals as those in FIG. A and FIG. 1B have the same functions, so a description thereof will be omitted. Note that the front view of the external appearance of this second embodiment is the same as the first one of the first embodiment.
Same as figure A.

Reference numeral 12 denotes an octave changeover switch group for changing and setting the pitch in octave units with respect to the pitch set by the fingering operation of the pitch setting switch group 2. This octave selection switch group 12 is connected to the pitch setting switch group 2.
A normal setting switch 12-1 for setting the pitch set by the pitch setting switch group 2, and a one-octave up switch 12- for changing and setting the pitch set by the pitch setting switch group 2 to a pitch one octave higher. 2. That pitch is 2
It consists of a two-octave up switch 12-3 for changing and setting a pitch an octave higher, and a one-octave down switch 12-4 for changing and setting the pitch one octave lower. Reference numeral 13 denotes a delay time setting switch group as delay time variable setting means, and a first delay which delays and outputs pitch information corresponding to the change when the fingering operation of the pitch setting switch group 2 changes. Select which delay time to change and set: time or a second delay time that delays and outputs pitch information corresponding to the change when the switching operation of octave switch group 3 changes.

-2 and a down switch 13-3.

FIG. 7 shows a wind instrument main body 101 shown in FIGS. 6A and 6B.
2 is an overall circuit configuration diagram of an electric circuit in FIG. 2, and the same reference numerals as those in FIG. 2 indicate those having the same functions, and a description thereof will be omitted.

The overall circuit configuration will be explained by describing the functions of the CPU 6.
The third function and the third function are the same as in the first embodiment.

The fourth #i function of the CPU 6 is to realize pitch information output control means, which is the key point of the configuration of this second embodiment, and for this purpose, the timer 14-1 and This is to control the musical tone generation circuit 7 based on a sound generation start instruction from the timer 14-2. That is,
During performance, when the on/off state of the pitch setting switch group 2 is changed by fingering operation in order to change the pitch of a musical tone, instead of immediately outputting pitch information to the musical tone generating circuit 7, When there is a change in the specified operation of at least one switch in the pitch setting switch group 2, the timer 14-1 issues an instruction to start sounding after a predetermined first delay time has elapsed from the time of the change. Based on this, new pitch information corresponding to the changed fingering operation is output to the musical tone generation circuit 7. Furthermore, in order to change and set the pitch set by the fingering operation of the pitch setting switch group 2 in octave units, the on/off state of at least one switch of the octave changeover switch group 12 is changed by the switching operation. When a change occurs, the pitch information for changing the octave is not immediately output to the musical sound generation circuit 7, but after a predetermined second delay time has elapsed from the time when the change occurs, the pitch information is output from the timer 14-2. It is configured to output new pitch information corresponding to the changed octave information to the musical tone generation circuit 7 based on a sound generation start instruction.

Then, when the delay time setting mode selection switch 13-1 in the delay time setting switch group 13 is operated and the switch 13-1 is connected to the voltage application terminal DE to which a predetermined voltage ■θ0 is applied, the delay time A predetermined voltage VOO is set to CP via the setting mode selection switch 13-1.
U6 is applied to select the mode for variably setting the first delay time to be set for the pitch setting switch group 2, and conversely, the delay time setting mode selection switch 13-1 is applied to the pitch setting switch group 2. , when connected to the ground terminal ET, the ground potential is applied to the CPU 6 via the switch 13-1, and a mode is selected in which the delay time of ff12 to be set for the octave changeover switch group 3 is variably set. It means that it was done. Here, when the up switch 13-2 is turned on with the delay time setting mode selected for either the pitch setting switch group 2 or the octave changeover switch group 12, the voltage va increases. The delay time is applied to the CPU 6, and the delay time is set longer by a predetermined time, for example, in units of 5m5ec, for each on-operation. When the down switch 13-3 is turned on, voltage Vb is applied to the CPU 6, and conversely, the delay time is set short by a predetermined time, for example, in units of 5 msec each time the down switch 13-3 is turned on. Note that if the up switch 13-2 and down switch 13-3 are turned on at the same time, the delay time will be set to an intermediate value, for example, 20 m5ec. The operation of the CPU 6 that realizes this pitch information output control means will be further described later.

FIG. 8 is a diagram showing an example of the relationship between the fingering operation of the pitch setting switch group 2 and the switching operation state of the octave changeover switch group 12 and each note on the staff of the musical score in the electronic wind instrument of the second embodiment. be. That is, the hand movement operation diagram of the pitch setting switch group 2 corresponding to the pitch of each note 64 to B3 shown on the staff notation of the musical score of FIG. 8(1) is shown in FIG. 8(2), and the black circle The mark indicates the switch-on state, and the white circle mark indicates the switch-off state. FIG. 8(3) is a switching operation diagram of the octave changeover switch group 12 corresponding to the pitches of each note 04 to B3 shown in the musical score of FIG. 8(1), and the black square marks are in the ON state. , and the white square mark indicates the switching off state. Here, for example, in order to set the pitch of the first note G4 shown in FIG. 8 (1) and change it to the pitch setting of the first note Aa', use the pitch setting switches 2-5 to
By turning on the octave selector switch 12-7 and switching the octave selector switch 12-1 with your left hand to the normal state, you can set the pitch of the GA. 2-5 is turned off, pitch setting switches 2-6 and 2-7 are kept turned on, and the sharp switch 2-9 is turned on with the left hand. The same switching operation is maintained for the octave changeover switch 12-1.

As a result, in order to change the pitch from this A- pitch setting state where the pitch is set to ~- to the third pitch E5, you need to switch the pitch setting switch with your left hand. 2-5
Turn on the sharp switch 2-9, turn off the sharp switch 2-9, and use your right hand to press the new pitch setting switch 2-4.2-
Turn on octave selector switch 3 and turn on octave selector switch 1 with your left hand.
2-1 to the octave changeover switch 12-2 to change the pitch to one octave higher.

If you want to change the pitch from D5 to D4, or if you want to change the octave from G4 to B3, use the octave selector switch 12-
1 or 12-4.

In this way, in order to change the pitch from one pitch to another, multiple pitch setting switches 2-6 to 2-7 and octave selection switches 12-1 to 12-4 must be simultaneously switched. There is a need to. At this time, with conventional electronic musical instruments,
All these finger operations of both hands must be performed at the same timing, and if there are variations in the timing, incorrect pitch information and musical tone information will be output to the musical tone generation circuit 7 at the moment of incorrect operation state. , a musical tone with an unnecessary pitch is emitted.Especially, the octave changeover switch group 1 is operated with the thumb compared to the fingering operation of the pitch setting switch group 2.
The switching operations in step 2 are difficult and require quite advanced techniques to synchronize the timing of these operations.

In this second embodiment, in order to prevent such inconvenient musical tones from being emitted, when the fingering operation state of the pitch setting switch group 2 is changed, the timer 14-1 is operated from the time of the change. Based on the sound generation start instruction from the timer 14-1, the delay time setting switch group 13 sets a predetermined first delay time (this delay time is at least The pitch information from the pitch setting switch group 2 is output to the musical tone generation circuit 7 via the CPU 6. It is configured to delay the Furthermore, when the switching operation status of the octave selection switch group 12 is changed, the timer 14-2 is operated from the time of the change, and the sound generation start instruction from the timer 14-2 is similarly performed. ,
The delay time setting switch group 13 selects a predetermined second value set in advance for the octave switching switch group 12.
(This delay time is also set in consideration of at least the time required for the octave off operation to stabilize at the correct octave setting state, as in the case of pitch setting switch group 2. ) is configured to delay the output of pitch information from the octave changeover switch group 12 to the musical tone generation circuit 7 via the CPU 5.

Therefore, the musical tone generation start instruction information is sent from the CPU 6 to the musical tone generation circuit 7 with a delay of each delay time set in advance by the delay time setting switch group 13, and as a result, there is no inconvenient musical tone generation and the musical tone is changed. A musical tone of a desired pitch is generated.

Furthermore, in this embodiment, the timer values of the timers 14-1 and 14-2 are set in order to arbitrarily set the length of the delay time in accordance with the skill level of the fingering operation of the performer. A delay time setting switch 913 is provided for this purpose, and by operating this switch, the lengths of the first and second delay times can be independently and arbitrarily set. The procedure for setting this delay time will be described in detail later with reference to Figure i9.

Operation of the Second Embodiment Next, referring to FIG. 9, FIG. 1O, and FIG. The operations of the CPU 6 and the timers 14-1 and 14-2 will be described.

FIG. 9 is a flowchart for variably setting the first and second delay times described above, and this flow
The main routine (not shown) in the operation of U6 is interwoven with a timer, or is started by repeating the operation at a predetermined timing.

First, in step 9-1, it is checked whether the up switch 13-2 in the delay time setting switch group 13 has been turned on, and if it is determined as YES, 1 is set in the up flag in step 9-2. Check whether it is installed or not. When it is determined as YES, it means that the up switch 13-2 has already been turned on, so it is checked in step 9-3 whether or not the down main switch 3-3 has also been turned on at the same time. When it is determined, there is no need to perform any new processing and the process returns to the main routine.

However, if YES is determined in step 9-3, this means that a selection operation has been made to set the delay time to an intermediate value. Set the value data to 0.

Next, the process proceeds to step 9-5, where it is checked whether the delay time setting mode selection switch 13-1 has been operated to select the selection mode for the pitch setting switch group 2, and the result is YES.
If it is determined as S, this means that the selection mode for variably setting the first delay time for the pitch setting switch group 2 is selected, so in step 9-6, the pitch timer buffer KEYTIM is selected. As a result, when the pitch setting switch and the fingering operation of G group 2 change, new pitch information corresponding to the change is written to the musical sound generation circuit 7 from the time of the change. 1st delay time for output from timer 14-1 (time corresponding to the above intermediate value data, for example, time of 20 m5ec)
After is set, return to main routine, step 9
If it is determined NO in step 9-5, this means that the selection mode for variably setting the second delay time for the octave setting switch group 12 has been selected, so in step 9-7 the octave When the intermediate value data O is written to the +JJ conversion timer buffer OCTTIM and the octave change switch n12 is operated in the same manner, new octave change information corresponding to the change is written in the same manner from the time of the change. After delaying by a time corresponding to the intermediate value data, a second delay time for outputting from the timer 14-2 to the musical tone generating circuit 7 is set, and then the process returns to the main routine.

If it is determined No in step 9-2, this means that the up switch 13-2 has been turned on anew, and the setting is to be changed to increase the delay time, so step 9- At step 8, data (+1) for lengthening the delay time by one step (for example, by 5 m5ec) is set in the A buffer. Then, the process proceeds to step 9-9, and the delay time setting switch 13-
1 is operated to select the selection mode for the pitch setting switch group 2, and if it is determined as YES, the selection for variably setting the first delay time for the pitch setting switch group 2 is checked. mode has been selected, in step 9-10 the first delay time data previously stored in the pitch timer buffer KEYTIM is moved to B/< buffer, and in the next step 9-10
At step 11, the result of the addition operation with the data (+1 in this case) set in the A buffer at step 4-8 is set in the pitch timer buffer KEYTIM, and the process returns to the main routine. That is, in response to the current ON operation of the up switch 13-2, a new delay time is set by varying the first delay time by one step longer. If NO is determined in step 9-9, this means that the selection mode for variably setting the second delay time for the octave change switch group 12 has been selected, so the octave change has been The data stored in the timer buffer OCTTIM is moved to the B buffer, and in the next step 9-13, the result of the addition operation with the data (+1) previously set in the A buffer is set in the octave timer buffer OCTTIM.
In response to the current ON operation of the up switch 13-2, a new second delay time is set, in which the delay time is increased by one step, and the process returns to the main routine. Note that in step 9-12, the data value of the B buffer has already been set to the maximum value (for example, +10) or the minimum value (for example, -10).
If so, it is assumed that the data value of the B buffer is not changed.

When it is determined NO in step 9-1.

Since the up switch 13-2 has not been turned on, it is checked in step 9-14 whether the up flag is 1 or not. If YES is determined here,
Set O to the up flag to reset it, indicating that the up switch 13-2 is not being turned on, and proceed to step 9.
Proceed to -16.

If it is determined NO in step 9-14, there is no need to set the up flag again, so proceed to step 9-16. In step 9-16, check whether the town switch 13-3 is turned on or not. Check it and press Y
When '1' is disconnected from ES, check whether 1 is set in the down flag in step 9-17 and select YES.
When it is determined that the down switch 13-3 has already been turned on, step 9-
Proceeding to step 3, the same processing as in the case described above is performed, so explanation II thereof will be omitted. If the determination in step 9-17 is No, this means that the down switch 13-3 has been turned on anew, and therefore the setting should be changed to shorten the delay time. Step 9-1
At step 8, data (-1) for shortening the delay time by one step (for example, by 5 m5ec) is set in the A buffer that stores the delay time setting data. The process then proceeds to step 9-9, where the same processing as described above is performed to set newly shortened first and second delay times, and the process returns to the main routine. Also, N at step 9-16.

When it is determined that neither the up switch 13-2 nor the down switch 13-3 has been turned on, it is checked in step 9-19 whether or not the down flag is set to 1.

If it is determined to be YES, the down flag is reset to 0 in step 9-20, and this time it is displayed that the down switch 13-3 has not been turned on, and the process returns to the main routine. When it is determined that no change is required, the process returns to the main routine.

FIG. 10 is a scanning flowchart of the pitch setting switch group 12 and the octave changeover switch group 12 in the electronic wind instrument of the second embodiment. This is a flow as a subroutine that operates repeatedly.

First, in step 10-1, the on/off operation status of the pitch setting switch group 2 is scanned and read, the pitch information read by this scanning is stored in the current pitch information buffer NEWB, and the next In step 10-2, it is determined whether the current pitch information is the same as the contents of the previous pitch information buffer 0LDB in which the pitch information read last time was stored. If it is determined as YES, there is no change in the pitch setting switch group 2 for changing the pitch, so proceed to the next step 10-3.If it is determined as NO, then proceed to the next step 10-3. On the contrary, since there has been a change, the process proceeds to step 1O-4, and the first pitch preset in the pitch timer buffer KEYTIM is changed.
After setting data corresponding to the delay time in the time buffer TIMBF built in the CPU 6 in preparation for counting the first delay time, the process proceeds to step 10-3.

In step 10-3, the octave changeover switch 12
The switching operation status is scanned and read, and the octave change information read by this scanning is stored in the current octave change information buffer NEWO.In the next step 1O-5, the current octave change information is the octave change read last time. Check whether it is equal to the information, and if it is determined to be YES, proceed to step 10.
The previous stay in -6, the pitch setting data from this scanning stored in step 1o-1 and the previous step 1O
The result of the addition operation with the octave change data from the current scanning stored in step -3 is stored in the current pitch data buffer KEYNEW in which the current pitch data is stored, and the process proceeds to the next step 10-7. Note that step 1
If it is determined NO in 0-5, step 10-8
The data previously stored in the octave switching timer buffer OCTTIM is transferred to the time buffer TIMB.
Move to F and proceed to step 1O-6.

In step 10-7, the current pitch data buffer KE is
The data content of YNEW is the previous pitch data buffer KEYOL that stores the pitch data from the previous scanning.
Check whether it is equal to the data content of D, and select YES.
When it is determined that

Since there is no change in pitch and there is no need to output new pitch information, the process returns to the main routine. However, if the determination is No, it is necessary to output new pitch information, so proceed to the next step 1O-9. Proceed to step 10-9
It is checked whether the pitch change flag in the timer 14-1.14-2 is set to 1, and if it is determined to be YES, the timer 14-1.14-2 is counting. At step 10-10, the pitch data stored in the current pitch data buffer KEYNEW is transferred to the previous pitch data buffer in preparation for the next scanning, and then the process returns to the main routine.

If it is determined as No, it means that the timer 14-1.14-2 has not started counting yet, and the sound generation is to be newly delayed this time, so the next step 10-11 is executed.
1 is set in each pitch change flag, and then in step 10-12, in order to delay the output of pitch information by a predetermined time when changing the pitch, the time buffer TI MB F is set in advance. After setting the data corresponding to the first and second delay times in the built-in timer 14-1.14-2 of the CPU 5 and starting the counting of the timer 14-1.14-2, the main routine starts. Return to.

In this way, in this scan flow, pitch setting switch group 2 or octave +
It scans whether there is a change in the on/off operation status of the JJ exchange switch group 12. When a change is detected, the timer 14-1 or 14-2 starts counting and sets the pitch. 'I!' for delaying pitch information output from the switch group 2 or the octave changeover switch group 12 to the musical tone generation circuit 7 via the CPU 6 by the respective set times. It is designed to count the elapsed time, and even if there is a change in the state of the pitch setting switch group 2 or the octave changeover switch group 12, the changed pitch information is immediately output to the musical tone generation circuit 7. The key point of the operation of this embodiment is that it does not.

Next, FIG. 11 is a flowchart of pitch change processing, and this flow is timer-interrelated with the main routine.

First, in step 11-1, it is determined whether the value of the digital breath information based on the breath information detected through the breath sensor 1 while playing exceeds the level of a predetermined key-on setting value that should instruct the start of sound generation. If it is determined as YES, the key is on, that is, the musical tone is being produced.
In step 11-2, the data in the current pitch information buffer NEWB or the previous pitch information buffer 0LDB is sent to the musical tone generation circuit 7 as pitch information, and the pitch information is based on the current or previous fingering operation. A musical tone having a pitch corresponding to the on/off state of the pitch setting switch group 2 is generated.

Next, stay and timer 14-1.14- at step 11-3.
2 change flag is reset to 0, and in step 11-4, the count of the timer 14-1 and 14-2 is stopped in preparation for the first state change of the pitch setting switch group 2 and the octave changeover switch group 12. After that, the program returns to the main routine and completes the operation.

Also, if it is determined NO in step 11-1,
This is a case where the value of the digital breath information has not reached the key-on setting value, and it is not yet time to instruct the start of musical tone generation, but the key is currently off, so proceed to step 11-3.
The following operations are performed in the same way as when the key is on, and the process returns to the main routine.

As described above, in this flow, based on the pitch information whose settings have been changed by the fingering operation on the pitch setting switch group 2 or the switching operation on the octave changeover switch group 12, the musical tone currently being sounded is changed to the new musical tone after the change. Processing to generate a pitched musical tone and timer buffer TI
A timer process is performed to count the elapse of a predetermined delay time set in MBF and control the timer intertwined start time of this flow.

Note that in the above embodiment, the CP is used to count the delay time.
A built-in timer 14-1.14-2 is specially provided in U6, but instead of this timer 14-1.14-2, the above 11 extension times can be counted by counting the number of repeated operations of the main routine. In this case, for example, the main routine is 4ms e c
If the operation is repeated at a tempo of , the data value of the timer buffer T I MB F may be set to 5 or 9, for example.

Effects of the Second Embodiment As mentioned above, in the electronic wind instrument according to the second embodiment, when the pitch setting switch group is
When the fingering operations (2-1 to 2-8) change, instead of immediately outputting new pitch information corresponding to the changed state to the musical tone generation circuit 7, the timer 14-1 starts generating sound. Based on the instruction, the musical tone generation circuit 7 is activated only after a predetermined first delay time (this delay time is set taking into consideration at least the time required to complete a correct and stable fingering operation). In contrast, the new pitch information is output, and based on this pitch information, the musical tone generating circuit 7 generates a musical tone with a new pitch corresponding to the changed fingering operation. Similarly, when the switching operation of the octave switching switch group 12 changes, instead of immediately outputting new octave change pitch information corresponding to the change to the musical tone generation circuit 7, the timer 14-
2, a predetermined second delay time (this delay time also takes into account at least the time required to complete a correct and stable switching operation, as in the case of pitch setting switch group 2). Pitch information for changing the octave is output to the musical tone generating circuit 7 only after the period (set by the octave) has elapsed. Therefore, if the fingering operations on the pitch setting switch group 2 and the switching operations on the octave changeover switch group 12 are in a transient state in which the operation state is not stable, that is, the plurality of pitch setting switches 2- The timing of operations 1 to 2-7 does not match each other and varies, and each pitch setting switch 2-
Even if 1 to 2-7 are operated with a time difference, it is possible to prevent musical tones of unnecessary pitches from being produced. In addition, the operation timing of the pitch setting switches 2-1 to 2-7 and each switch 12-1 to 12 of the octave selection switch group 12 are also explained.
Even if the switching operation timings of -4 and 4 do not match each other and vary, it is possible to prevent musical tones with unnecessary pitches from being produced. Furthermore, unlike conventional models, there is no muffling circuit, so the musical tones are not interrupted temporarily, but the pitch can be changed while the musical tones continue to be emitted smoothly. This has the effect of allowing you to perform with natural pronunciation.

Further, the timer 14-1 and the timer 14-2 set the first and second delay times for delaying the output of the pitch information by a predetermined time, and the delay time setting switch group 13 allows the performer to adjust the delay time according to his or her playing skill. Since the delay time can be set arbitrarily and variably according to the player's skill level of the fingering operation and the switching operation, the delay time can be set according to the level of the technique of the fingering operation and the switching operation, making it very effective and easier to play. It becomes easy.

Third Embodiment> Further, a third embodiment of the electronic wind instrument according to the present invention (the invention set forth in claim 5) will be described with reference to FIG.

Section 3 - Structure and operation of embodiment With reference to FIGS. 6A, 6B, and 7, this third embodiment
In the embodiment, C functions as pitch information output control means.
The processing operation of PU6 will be described. In addition, the above-mentioned 6th
The external appearance of the electronic wind instrument and the overall circuit configuration of the electronic circuit in the second embodiment shown in Figures A, 6B, and 7 are the same as in the third embodiment, so a detailed description thereof will be given below. Omitted.

FIG. 12 is a pitch setting switch/octave changeover switch scanning flowchart, which is a subroutine that repeatedly operates at a predetermined timing with respect to the main routine (not shown) of the CPU 6.

First, in step 12-1, the on/off operation status of pitch setting main channel group 2 is scanned and read, the pitch information read by this scanning is stored in the current pitch information buffer NEWH, and the first step is performed. 1
In step 2-2, it is determined whether the current pitch information is the same as the contents of the previous pitch information buffer 0LDB in which the pitch information read last time was stored. If it is determined as YES, there is no change in the pitch setting switch group 2 for changing the pitch, so proceed to the next step 12-3; if it is determined as NO, then, On the contrary, since there has been a change, the process proceeds to step 12-4, and the first delay preset in the pitch timer buffer KEYTIM is set by the delay time setting switch group 13 (see FIGS. 6A and 7). In this case, the fingering operation for pitch setting switch group 2 is relatively roomy, so data of 20 zsec, which is a relatively short delay time, is set in the time buffer TIMBF built in the CPU 6 to count the delay time. After preparing for this, the process proceeds to step 12-3.

In step 12-3, the octave changeover switch 12
Scan and read the switching operation status of , and store the octave change information read by this scanning into the current octave change information buffer NEWO. In the next step 12-5, the current octave change information is changed to the previously read octave change. Check whether it is equal to the information, and if it is judged as YES, Stella 7'l
In 2-6, the pitch setting data from the current scanning stored in the previous step 12-1 and the previous step 1
The result of the addition operation with the octave change data due to the current scanning stored in step 2-3 is stored in the current pitch data buffer KEWNEW that stores the current pitch data, and the process proceeds to the next step 12-7.Step 12
If it is determined No in step 12-5, then in step 12-8, the delay time setting switch group 13 (see FIGS. 6A and 7) sets the second value previously stored in the octave switching timer buffer OCTTIM. The delay time, in this case, is 35 m5ec, which is a relatively long delay time, since the switching operation for the octave changeover switch group 12 is difficult compared to the fingering operation for the pitch setting switch group 2.
data is transferred to the time buffer TIMBF and the process proceeds to step 12-6. In step 12-7, the data content of the current pitch data buffer KEYNEW is changed to the previous pitch data buffer KEYOLD in which the pitch data from the previous scanning was stored. If the result is YES, there is no change in pitch and there is no need to output new pitch information, so the process returns to the main routine, but it is determined as NO. If so, it is necessary to output new pitch information, so proceed to the next step 12-9. In step 12-9, check whether the pitch change flag in timer 14-1.14-2 is set to 1. If it is determined as YES, timer 14-1.14-2 is counting.
In step 12-10, set the current pitch data buffer KEY.
The pitch data stored in NEW is transferred to the previous pitch data buffer in preparation for the next scanning, and then the process returns to the main routine. When the judgment is NO, timer 1
4-1.14-2 is the case where the count has not yet started, and this time the pronunciation is newly delayed, so in the next step, B12-11, set each pitch change flag to 1, and then Then, in step 12-12, in order to delay the output of pitch information by a predetermined time when changing the pitch, a delay time corresponding to the first and second delay times preset in the time buffer TI MB F is set. After setting the data in the built-in timers 14-1 and 14-2 of the CPU 6 and starting the counting of the timers 14-1 and 14-2, the process returns to the main routine.

Next, the fingering operation of the pitch setting switch group 2 and the octave changeover switch group 1 in the electronic wind instrument of the third embodiment will be explained.
2 cuts! ! ! ! The operation state will be described based on FIG. 8 above.

To change from playing the first note 64 to playing the next A4M, press the octave selector switch 1T12, 9.
Since there is no change in the switching operation, the musical tone A4g is produced with a delay of the first delay time (for example, 20 m5ec) that is set in advance in response to the change in the r1 high setting > if switch 112. Next, when changing the pitch from A- to E5, both the pitch setting switch group 2 and the octave changeover switch group 12 change, so in this case, in response to the change in the octave changeover switch group 12, A second delay time that is set in advance to be longer than the first delay time (for example, 35
The musical tone E5 is sounded with a delay of m5ec). Similarly, in the next change from E5 to D5, there is no change in the octave change switch group 12, so the first delay time (20 msec
), the pronunciation is delayed. Subsequently, the change from D5 to D4 is delayed by the second delay time (35 msec) because the pitch setting switch group 2 does not change, but the octave changeover switch group 12 changes, and from D4 to D4 in the following order.
The change from G4 to B3 is delayed by the first delay time, and the change from G4 to B3 is delayed by the second delay time. In other words,
In this third embodiment, Octa! :12 When there is a change in the switching operation of the switch group 12, the start of sound generation is delayed by a second delay time set to a longer time.

Note that the pitch change processing operation of the CPU 6 functioning as the pitch information output control means in this embodiment is the same as the operation in the second embodiment shown in FIG. 11, so a description thereof will be omitted.

In the third embodiment, the timers 14-1 and 14-2 built into the CPU 6 are provided to count each delay time, but the timers 14-1 and 14-2 may be configured to count the operating rotation speed of the main routine.

Effects of Third Embodiment This FF13 embodiment differs from the second embodiment in that it has a second delay time (in the case of this embodiment, 35
m5) is the first delay time for the fingering operation of the pitch setting switches 2-1 to 2-8 (in this example, 20 m).
Since the preset time is longer than 5), it is necessary to completely complete the switching operation of octave changeover switch group 12, which requires a more difficult operation technique than the fingering operation of pitch setting switch group 2. Since a delay in sound generation can be ensured, it is possible to prevent a musical tone of an unnecessary pitch from being temporarily emitted when the octave changeover switch group 12 is operated. . Therefore, it is not necessary to make the first delay time for the fingering operation of the pitch setting switch group 2 coincide with the second 'ji delay time for the octave changeover switch group 12, and the first 'N delay time is sufficient. Since the electronic wind instrument can be set to a short or short length, even when performing fast trills, etc., it is possible to prevent the sound from being emitted with an unnecessary delay after the fingering changes. This has the effect that it can be obtained.

Note that when both the pitch setting switch group 2 and the octave changeover switch group 12 change, the delay time is further increased to, for example, 45m5ec, and when only the octave changeover switch group 12 changes, the delay time is increased to 35m5ec. It may be configured to do so.

Modified Embodiment It should be noted that unlike the first, second and third embodiments described above,
The musical sound generation circuit 7 and the musical sound output device 10 are included in the wind instrument main body 101
These musical tone generation circuit 7 and musical tone output '4! 10 may be electrically connected to the main body 101 of the wind instrument.

Furthermore, the external shape of the main body of the electronic wind instrument is not limited to the saxophone type, but may be other shapes such as a clarinet.

[Effects of the Invention] As described above, according to the invention as set forth in claim 1, when the fingering operations of the plurality of pitch setting switch means in the pitch setting means change during performance by the breath operation, the change From this point on, the new pitch information is outputted to the musical sound generating means after a predetermined delay time without immediately outputting the pitch information corresponding to the change in the fingering operation to the musical sound generating means. Therefore, the fingering operations of the multiple pitch setting switch means by A Nagisa were not done at the same time, and as a result, the fingering operations were performed in a state that varied over an hour, and as a result, the moment when the correct fingering operations were not performed at the same time. Even if something occurs, musical tones with unnecessary pitches will not be generated at that moment. Therefore, not only for beginners but also for those with some experience, the musical tones can be emitted without interruption. This has the effect of providing an electronic wind instrument that can smoothly change the pitch without any unnaturalness while continuing to produce musical tones, and can perform favorably.

According to the invention set forth in claim 2, since the structure of the invention set forth in claim 1 is further provided with variable delay time setting means, in addition to the effect of the invention set forth in claim 1, each sound of the performer is Since the performer can arbitrarily set the delay time according to the level of the fingering operation technique for the high setting switch, beginners may find it useful to set the delay time long enough to hear the musical tone after the fingering operation. Therefore, it is not only extremely easy to play, but also useful for advanced players by setting the delay time short, so that the sound of the musical note after the fingering change is delayed more than necessary. This has the effect of providing an electronic wind instrument that can perform songs with fast tempos and fast passages without any noise.

According to the invention as claimed in claim 3, when the fingering operations of the plurality of pitch setting switch means in the pitch setting means change during a performance using the breath operation, from the point of time when the fingering operations change, the change in the fingering operations is performed. The corresponding pitch information is not immediately outputted to the musical sound generating means, but the new pitch information is outputted to the musical sound generating means after a predetermined first delay time has elapsed, and the octave switching means is switched. Even when the operation changes, the pitch information of the octave change corresponding to the change is not immediately output to the musical sound generating means, and the predetermined second
Pitch information for changing the octave is output to the musical tone generating means only after the delay time elapses. For this reason, if a transient state occurs in which the fingering operation on the pitch setting switch means and the switching operation on the octave changeover switch are not stable at the predetermined operation state Jg, that is, when a transitional state occurs in which the fingering operation on the pitch setting switch means and the switching operation on the octave changeover switch are not stabilized at the predetermined operation state Jg, Even if the timing of fingering operations and switching operations of multiple octave selection switches do not match each other and are operated with a time difference, it is possible to prevent musical tones with unnecessary pitches from being produced. . Also, if the fingering operation timing of each pitch setting switch means and the switching operation timing of the octave switching switch and chi means do not match each other and vary, musical tones with unnecessary pitches can be prevented from being produced. Not only can this be prevented, but unlike conventional models, there is no silencing circuit, so musical tones can be emitted continuously without any temporary interruptions, and smooth octave switching is possible. This has the effect of providing an electronic wind instrument that can change pitch.

Further, according to the invention set forth in claim 4, in the structure of the invention set forth in claim 3, a first delay time for the fingering operation of the pitch setting switch means and a second delay time for the switching operation of the octave switching means are provided. The time can be set independently and variably! Since the delay time variable setting means is further provided, in addition to the effect of the invention as set forth in claim 3, the delay time variable setting means can also be set according to the level of each technique of the fingering operation and switching operation of the performer.
This has the effect of providing an electronic wind instrument in which the player can variably set the first and second delay times as desired.

Furthermore, according to the invention as set forth in claim 5, the second delay time for the switching operation of the octave switching means is set in advance to a longer time than the first delay time for the pitch setting switch means. Therefore, when performing a switching operation of the obve switching means, which is more difficult to operate than fingering operations for each pitch setting switch, the musical tone after the switching operation can be produced sufficiently slowly, while the operation is relatively easy. When a simple fingering operation of a pitch setting switch means is performed, the musical tone after the fingering operation is generated sufficiently early, and a fast tempo performance or a trill performance can be performed without delay in the generation of the musical tone. This has the effect of providing an electronic wind instrument that can perform various functions.
