Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument, and more particularly to an electronic musical instrument having a musical performance operator for instructing the sounding of musical tones and a musical performance operator for controlling the parameters of the musical tones to be generated.

[0002]

2. Description of the Related Art In natural musical instruments, musical tones of different tones are produced by using the same musical instrument, depending on the playing method.

For example, in the method of playing a triangle,
A method of producing a musical tone without suppressing the sound of the triangle hit by a stick with the hand holding the triangle (hereinafter, the musical tone of the timbre produced by this method is referred to as an "open tone"), There is a method in which the sound of the triangle hit by the stick is suppressed by the hand holding the triangle to produce a musical sound (hereinafter, the musical sound of the tone color produced by this method is referred to as a "mute sound"). By properly selecting the method, the triangle can emit an open sound and a mute sound.

Further, as a matter of course, with a single triangle, the open sound and the mute sound cannot be sounded at the same time.

That is, if the mute sound is to be generated while the open sound is being sounded, the mute sound is sounded after the open sound is muted. On the contrary, if the open sound is to be produced while the mute sound is being produced, the open sound is produced after the mute sound is muted.

On the other hand, when an open tone is being pronounced,
When a performance in which an open sound is repeatedly pronounced continuously is performed, the next open sound is sounded while the sounded open sound remains unchanged. In addition, even when playing a mute sound repeatedly and continuously, the same mute sound is played, and the next mute sound remains unchanged, as in the case of playing an open sound repeatedly and continuously. The sound will be pronounced.

Conventionally, in the field of electronic musical instruments, various methods have been proposed for simulating such natural musical instruments, such as the above-mentioned triangle, simulating natural musical instruments in which musical tones having different timbres are not generated at the same time. In order to achieve this, the following method has been proposed.

That is, tones such as triangle open sound and mute sound that are not simultaneously pronounced are grouped into the same group, and when a new tone is to be sounded, let's pronounce it. If a tone of another tone color that belongs to the same group as the tone of the tone to be played is already being sounded, the tone being sounded is rapidly attenuated before a new tone is sounded. Further, in the case of continuously producing musical tones of the same tone color, it is possible to select whether or not to rapidly attenuate the musical tone being produced.

In the following description, when a musical tone of the same tone color is continuously pronounced, the selection as to whether or not the musical tone being sounded is rapidly attenuated is called "polyphony", and the musical tone being sounded is rapidly damped. The case where the musical tone is being produced is called "mono", and the case where the musical tone being produced is not rapidly attenuated is called "poly".

In addition, when a tone color that is not sounded at the same time is divided into the same group, a tone color (hereinafter, "tone" is referred to as "instrument" if necessary) in a group, polyphony, or electronic musical instrument. A number assigned to each tone color for searching (hereinafter referred to as "instrument number") and the like are referred to as musical tone attributes.

For example, in order to simulate the above-mentioned triangle with an electronic musical instrument, the attributes of musical tones may be set as follows. The tone color of the open sound is referred to as "Open Triangle", and the tone color of the mute sound is referred to as "Mute Triangle".

That is, tone polyphony group open triangle poly poly mute triangle same mute triangle poly open triangle By setting the same as, it is possible to perform a simulation of a natural musical instrument triangle.

[0013]

By the way, an electronic musical instrument is provided with a performance operation element such as a pad or a key for instructing the pronunciation of a musical sound, and a performance operation provided separately from the performance operation element for instructing such pronunciation. It is known to operate a manipulator to control parameters such as tone color and volume of a musical tone instructed to be sounded.

For example, Japanese Unexamined Patent Publication No. 1-266596 discloses an electronic musical instrument provided with the above-described two types of performance operators. The electronic musical instrument disclosed in Japanese Unexamined Patent Publication No. 1-266596 is disclosed. Can produce a musical sound similar to that of a natural percussion instrument such as a hi-hat by performing a performance operation similar to that of a natural percussion instrument such as a hi-hat.

The electronic musical instrument disclosed in the above-mentioned Japanese Patent Laid-Open No. 1-266596 has a performance manipulator for instructing sounding of a hi-hat sound by striking, and a foot pedal as a performance manipulator different from the performance manipulator. I have it. Then, when a performance operation is performed by striking the performance operator, it is possible to instruct to generate a hi-hat sound having a tone color corresponding to the depression position of the foot pedal. That is, in the state in which the foot pedal is fully depressed (simulating the state in which the hi-hat cymbals are combined), a musical sound (hereinafter referred to as a close sound) that is sounded when hit with the state in which the hi-hat cymbals are combined. ) Is sounded and the foot pedal is released (simulating the state where the hi-hat cymbal is distant.), The tones produced when the hi-hat cymbal is struck apart (hereinafter referred to as the open tone). Pronounce).

In addition, when the hi-hat sound is being produced, the foot
By operating the pedal, you can change the envelope of the hi-hat sound being produced.

That is, when the performance operator is hit to perform a performance operation while the foot pedal is released, and then the foot pedal is depressed, the envelope of the musical sound being sounded as an open sound is changed and closed. The sound comes to be heard. When the foot pedal is fully depressed, the performance operator is struck to perform a performance operation, and when the foot pedal is released, the envelope of the musical sound being produced as a closed sound changes, and the open sound is changed. You will be heard.

In such an electronic musical instrument, in order to further simulate the playing of a high-hat of a natural musical instrument, the same instrument number (tone) polyphony group 1 (open hi-hat) poly-closed hi-hat as in the example of the triangle described above. 2 (Closed hi-hat) The same problems as those of the poly open hi-hat were set when the musical attributes were set and the performance control and foot pedal were operated (the open tone was "Open Hi-hat"
The tone of the closed sound is called the "closed hi-hat").

That is, (1) the performance operator is operated with the foot pedal depressed, and a hi-hat sound (closed sound) of the closed hi-hat tone is generated. At this time, the instrument
The number is set to "2 (closed hi-hat)". (2) Immediately after the operation in (1) above, release the foot pedal to change the parameter (envelope, etc.) of the high-hat sound (close sound) being sounded, and change the tone of the high-hat sound (close sound) being sounded. , Change it to be heard as an open tone. However, in this case, instead of operating the performance operator to generate a new musical sound, the closed
Since the parameter of the hi-hat sound of the hi-hat tone is changed, the instrument number does not change and remains "2 (closed hi-hat)". (3) When the performance controller is operated again, the foot pedal is released, so the instrument number "1 (open hi-hat)" is set as the instrument number of the musical sound to be produced, An open sound will be pronounced. Here, the instrument number “1 (open hi-hat)” and the currently-pronounced instrument number “2 (closed hi-hat)” belong to the same group and have different instrument numbers. The musical sound that changed the hi-hat sound of the instrument number "2 (closed hi-hat)" being sounded into an open sound,
It will be rapidly attenuated. (4) However, the currently sounding tone that is rapidly attenuated is
Since the sound is being heard as an open sound, even though the open sound was pronounced after the open sound, the musical sound being currently sounded is interrupted, which gives an unnatural feeling. There was a problem.

In addition, the following problems may occur.

That is, (1) the performance operator is operated with the foot pedal depressed, and a hi-hat sound (closed sound) of the closed hi-hat tone is generated. At this time, the instrument
The number is set to "2 (closed hi-hat)". (2) Immediately after the operation in (1) above, release the foot pedal to change the parameter (envelope, etc.) of the high-hat sound (close sound) being sounded, and change the tone of the high-hat sound (close sound) being sounded. , Change it to be heard as an open tone. However, in this case,
Instead of operating the performance controller to produce a new musical sound, the closed instrument of the currently playing instrument number "2"
Since the parameter of the hi-hat sound of the hi-hat tone is changed, the instrument number does not change and remains "2 (closed hi-hat)". (3) Here, from the MIDI signal input terminal, a note corresponding to the hi-hat sound of the closed hi-hat tone
If you input the MIDI pronunciation information of the number, the instrument number
The number "2 (closed hi-hat)" is set, and a closed sound is emitted as a hi-hat sound. Here, the instrument number “2 (closed hi-hat)” and the instrument number “2 (closed hi-hat)” currently being pronounced belong to the same group and have the same instrument number. The musical sound that is generated by changing the high-hat sound of the instrument number “2 (closed hi-hat)” that is being sounded to an open sound is not rapidly attenuated. (4) However, since the musical sound being currently sounded is heard as an open sound, it is unnatural because the musical sound being sounded is not rapidly attenuated, even though the open sound is followed by the closed sound. It was giving a feeling of hearing. There was a problem.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a performance manipulator for instructing the generation of a musical tone and a musical performance in which the parameters of the musical tone are changed. When a new musical tone is instructed while changing the parameters of the musical tone being produced, the musical tone is not heard unnaturally, and the musical tone that is heard as the operation of the performance operating device is provided. It is intended to provide an electronic musical instrument with improved followability with.

It is sent to U10. Also, when the electronic drum pad connected to the external trigger input terminal 24 is hit, a trigger signal is similarly generated, and this trigger signal is also transmitted to the bus 1
It is sent to the CPU 10 via 2.

The control signal input terminal 22 is a controller such as a foot pedal (hereinafter, unless otherwise specified, the term "controller" means a controller connected to the control signal input terminal 22). .) Is transmitted to the CPU 10 as a control signal via the bus 12 as a control signal.

As will be described later, the control signal controls the mixing ratio and the length (decay) of the two tones of the tone of the closed hihat and the tone of the open hihat. Achieves a change in the tone color of a musical tone, such as when operating the hi-hat of a musical instrument.

In FIG. 2, the control signal input terminal 22 is shown.
When the controller is connected to the connection terminal 22a, the switch SW turns off and the signal S

The hi-hat information table stores the value of each parameter including the attribute (group) of the musical sound for controlling the hi-hat sound according to the value of the control signal, in association with the value of the control signal.

As parameters, the volume level of the open tone of the tone color of the instrument number “3: Open HiHat” and the closed tone of the tone color of the instrument number “4: Closed HiHat” and A group of attributes for decay, note number, and tone is set.

As can be seen from FIG. 4, depending on the value of the control signal, when "control signal = 0 to control signal = 7", only the closing sound is sounded,
When "control signal = 8 to control signal 12", a hi-hat sound in which an open sound and a closed sound are mixed is sounded, and when "control signal = 13 to control 15", only an open sound is sounded.

When "control signal = 0 to control signal = 7", "note number = 4"
2 ”,“ control signal = 8 to control signal =
In the case of "15", "note number = 46" is assigned.

Furthermore, when "control signal = 0 to control signal 7", "group = 1" is grouped, and when "control signal = 8 to control signal 15", "group = 2" is grouped.

Various register groups are set in the RAM 16 as described above, and the registers related to the implementation of the present invention include the following. In the following description, the contents (data, etc.) of each register are represented by the same label name unless otherwise specified.

(1) TRGN This register stores the trigger number of the trigger signal.

(2) CNTRG This register stores the trigger number of the trigger signal controlled by the control signal of the controller.

The operation and operation of the above-described electronic musical instrument having the above structure will be described with reference to the flow charts shown in FIGS.

This electronic musical instrument is shown in FIG.
In the main routine, the CPU 10 is interrupted at regular intervals to execute the AD scan sub-routine shown in FIG. 6, and the trigger signal and the controller are executed. Output signal S2 is read by the CPU 10 and processed.

First, the main routine will be described with reference to the flowchart shown in FIG.

First, the main power is turned on by turning on the power.
When the routine is activated, in step S502,
It is determined whether or not the signal S1 is High. When this determination result is affirmative (Y), that is, when the controller is connected to the control signal input terminal 22 and the signal S1 is High, the process proceeds to step S504 and controller correction processing is performed. The controller correction process will be described later in detail with reference to FIG. When the controller correction process of step S504 is completed, the process proceeds to step S506.

Further, the determination result of step S502 is negative (N), that is, the signal S1 is low because the controller is not connected to the control signal input terminal 22.
If it is, the process proceeds to step S506.

In step S506, initialization processing is performed to initialize various registers. In this initial setting, the value of S1 is assigned to S and "0" is assigned to SREQ, and TRGLEVEL [1] to TRGLEV
Substitute “0” for L [11]. Further, the trigger number “3” (the trigger number to which the hi-hat sound is assigned) is assigned to the trigger number CNTRG of the trigger signal controlled by the controller connected to the control signal input terminal 22. Further, other registers are initialized.

When the initial setting process of step S506 is completed, the flow advances to step S508 to perform control signal processing. This control signal processing, which will be described in detail later with reference to FIG. 10, generates a musical tone when the controller is operated, and controls signal CN.
The value of each parameter of the musical tone is determined from TRL.

When the control signal processing in step S508 is completed, the tone generation processing is performed in step S510. This tone generation processing, which will be described in detail later with reference to FIG. 8, is performed when the electronic drum pad connected to the built-in pad section 20 or the external trigger signal input terminal 24 is struck. Generate.

Further, in the tone generation processing of step S510, the MIDI transmission buffer (not shown) is provided with a MIDI signal note corresponding to the strike of the electronic drum pad connected to the built-in pad section 20 or the external trigger signal input terminal 24.
A number or a MIDI signal (for example, control change) corresponding to the control signal CNTRL by the operation of the controller is written.

When the sound generation processing of step S510 is completed, the process proceeds to step S512, and MIDI reception processing is performed. In the MIDI reception processing, the same sound generation processing as in step S510 is performed based on the information of the MIDI signal input from the MIDI signal input terminal 26 and written in the MIDI reception buffer (not shown).

When the MIDI reception processing in step S512 is completed, the flow advances to step S514 to perform the MIDI transmission routine processing. In the MIDI transmission process, the note number, control change, etc. of the MIDI signal written in the MIDI transmission buffer in step S510 are sent to the MIDI signal output terminal 28. In this way, note numbers, control changes, etc. of the MIDI signal sent to the MIDI signal output terminal 28 are output to an external sound source device or the like to cause such a sound source device or the like to generate a musical tone. Control the tone of the.

When the MIDI transmission processing in step S514 is completed, the flow advances to step S516 to operate the operation panel 18
Other processing such as switch processing and display processing of the display unit 30 is performed.

When the process of step S516 is completed, the process returns to step S508, and the process of the loop of steps S508 to S516 is repeated.

Next, step S50 of the main routine.
The controller correction process of No. 4 will be described in detail based on the flowchart of the controller correction sub-routine shown in FIG.

First, in step S602, a display prompting the performer to perform an operation is displayed on the display unit 30 so that the value of the output signal S2 of the controller is maximized, and the process waits for a while. When a foot pedal for controlling the hi-hat is provided as the controller, the foot pedal is released when the output signal S2 has the maximum value.

When the processing of step S602 is completed, the routine proceeds to step S604, where it is determined whether or not the value of the output signal S2 is within the range between the preset minimum value SMIN and maximum value SMAX (minimum value SMIN). And the maximum value S
MAX is a constant. ).

The determination result of step S604 is negative, that is, the value of the output signal S2 is the minimum value SMIN and the maximum value SMA.
If it does not exist in the range of X, the process proceeds to step S606, a warning is displayed on the display unit 30, and the player is warned that the controller connected to the control signal input terminal 22 is unusable. Therefore, it is possible to prevent the performer from starting playing in a state where the controller that cannot be connected to the control signal input terminal 22 of the electronic musical instrument is connected. When the process of step S606 ends,
This controller correction sub-routine is ended.

On the other hand, if the determination result of step S604 is affirmative, that is, if the value of the output signal S2 is within the range between the minimum value SMIN and the maximum value SMAX, then step S60.
8, the operation of "S2 / 16" is executed, and the obtained value is stored in dCNTRL. That is, the control signal CNTRL is used to refer to the hi-hat information table.
The value dCNTRL of the output signal S2 for changing the signal level of 1 by "1" is obtained and stored in dCNTRL. When the process of step S608 ends, this controller correction sub-routine ends.

Next, the AD scan sub-routine activated every fixed time will be described with reference to FIG.

First, when the AD scan sub routine is started, it is determined in step S702 whether S is "0". This judgment result is affirmative, that is,
Control signal input terminal 2 at the last AD scan
If the controller is not connected to 2, the switch SW is turned on, and the value S of the previous signal S1 is "0", the process proceeds to step S704.

In step S704, the signal S1 is "0".
Is determined. If this determination result is affirmative, that is, if “S = 0 and S1 = 1” is satisfied, the controller is not connected to the control signal input terminal 22 at the time of the previous AD scan, and the control signal input terminal 22 is connected to the control signal input terminal 22 for the first time this time. When the controller is connected, the process proceeds to step S706, and the controller correction process described based on FIG. 6 is performed.

When the controller correction processing in step S706 is completed, the flow advances to step S708 to send a signal S to S.
The value of 1 is substituted, and the process proceeds to step S710.

Further, step S702 and step S
Even when the determination result of 704 is negative, step S710
Go to.

In step S710, TRGN is set to "1".
To prepare for the subsequent processing from the trigger number “1”.

When the process of step S710 is completed, the process proceeds to step S712, in which the trigger stored in TRGN is
It is determined whether or not the number trigger signal is input. As described above, the trigger signal is generated by striking each of the eight pads of the built-in pad section 20 and the electronic drum pads (three) connected to the external trigger signal input terminal 24, and is input to the CPU 10.

If the determination result of step S712 is affirmative, that is, if the trigger signal of the trigger number stored in TRGN is input, the process proceeds to step S714.

In step S714, the trigger magnitude (trigger level) of the trigger signal of the trigger number.
Is stored in the storage area of the trigger number stored in TRGN of TRGLEVEL [TRGN].

When the process of step S714 is completed, the process proceeds to step S716, in which SREQ is set to "1" to prepare to produce a musical tone. When the process of step S716 ends, the process proceeds to step S718.

Also, when the determination result of step S712 is negative, that is, when the trigger signal of the trigger number stored in TRGN is not input, step S718 is performed.
Go to.

In step S718, TRGN is set to "1".
After incrementing, TRGN in step S720
Is determined to exceed "11". Step S7
If the determination result of 20 is negative, that is, if TRGN does not exceed the maximum value of the trigger number, step S71
Returning to step 2, the above loop processing is repeated for all trigger numbers.

On the other hand, if the result of the determination in step S720 is affirmative, that is, if TRGN exceeds the maximum value of the trigger numbers, it means that the above loop processing has been completed for all the trigger numbers. Step S721
Go to.

In step S721, it is determined whether S is "0". If this determination result is affirmative, that is, if the controller is not connected to the control signal input terminal 22 and the switch SW is on, AD
Exit the scan subroutine.

On the other hand, if the determination result in step S721 is negative, that is, if the controller is connected to the control signal input terminal 22, the process proceeds to step S722.

In step S722, the output signal S2 of the controller is divided by dCNTRL and CNTRL.
Compares for equality. The determination result of step S722 is affirmative, that is, the output signal S2 of the controller is set to dCNT.
If CNTRL equal to the one divided by RL is equal, this AD scan sub-routine is ended.

On the other hand, the determination result of step S724 is negative, that is, the output signal S2 of the controller is set to dCNTRL.
If CNTRL is not equal to the value obtained by dividing by, the value obtained by dividing the output signal S2 of the controller by dCNTRL is C
Substitute NTRL and control request flag CNTREQ
Is set to "1" and the AD scan sub-routine is completed.

Next, step S51 of the main routine.
The sound generation processing of 0 will be described in detail with reference to the flowchart of the sound generation processing sub routine shown in FIG.

In this tone generation processing sub routine,
First, in step S802, it is determined whether SREQ is "1". Step S71 described above
As shown in 6, SREQ is set to "1" when a trigger signal is input.

If the result of the determination in step S802 is negative, that is, if there is no trigger signal input (for the eight pads of the built-in pad section 20 and the electronic drum pads (three) connected to the external trigger signal input terminal 24). If none of them has been hit), this sound generation processing sub-routine is terminated without performing any processing. Therefore, in this case, no musical sound is produced.

On the other hand, if the determination result of step S802 is affirmative, that is, if there is a trigger signal input (eight pads of the built-in pad section 20 and the external trigger signal input terminal 2).
If any one of the electronic drum pads (three) connected to No. 4 is hit), the process proceeds to step S804, and T
Substitute "1" for RGN, and prepare to perform subsequent processes from the trigger number "1".

When the process of step S804 is completed, the process proceeds to step S806, where the TRG of the trigger number is
It is determined whether or not the trigger level stored in LEVEL [TRGN] is "0". If the determination result of step S806 is affirmative, that is, if the trigger level is not "0", the process proceeds to step S808.

In step S808, the musical sound generating unit 3 is executed based on an assigner sub routine shown in FIG. 9 which will be described later.
2 is controlled to generate a musical sound.

When the process of step S808 ends, the process proceeds to step S810, the trigger information table is searched, and the note number of the MIDI signal corresponding to TRGN sent from the MIDI signal output terminal 28 is determined.
When the note number is "42: Hi-hat", CNTRL refers to the hi-hat information table,
Determine the note number.

When the process of step S810 is completed, the process proceeds to step S812, and the MIDI signal indicating the note number determined in step S808 is written in the MIDI transmission buffer.

When the process of step S812 is completed, the process proceeds to step S814, in which "0" is assigned to TRGLEVEL [TRGN] of the trigger number sounded in step S808 and "0" is assigned to SREQ, and the next Prepare for trigger signal input. Step S814
When the process of (3) is completed, the process proceeds to step S816.

Also, if the determination result of step S806 is negative, that is, if the trigger level is "0", the process proceeds to step S816.

In step S816, TRGN is set to "1".
After incrementing, TRGN in step S818
Is determined to exceed "11". Step S8
If the determination result of 18 is negative, that is, TRGN does not exceed the maximum value of the trigger number, step S80
Returning to step 6, the above loop processing is repeated for all the trigger numbers.

On the other hand, if the result of the determination in step S818 is affirmative, that is, if TRGN exceeds the maximum value of the trigger numbers, it means that the above loop processing has been completed for all the trigger numbers. , This tone generation processing sub-routine is ended.

FIG. 9 shows step S808 as described above.
Shows the assigner sub routine of.

First, in step S902, TRGN
And CNTRG are compared with each other to determine whether or not the musical sound to be produced is controlled by the controller. If the result of this determination is negative, that is, if the musical sound to be produced is not controlled by the controller, step S90
4, the trigger information table is searched to determine the instrument number (INST1) of the instrument to be sounded corresponding to the trigger number stored in TRGN.
Also, "0" is substituted for INST2 and "0" is substituted for GROUP. When the process of step S904 ends, the process proceeds to step S906.

On the other hand, if the result of the determination in step S902 is affirmative, that is, if the musical tone to be emitted is controlled by the controller, the process proceeds to step S908 and IN
The instrument number "3" of the open hi-hat tone is assigned to ST1, and the instrument number "4" of the closed hi-hat tone is assigned to INST2. Also, CN
The hi-hat information table is searched from the TRL to determine the volume level, decay, and group of the open hi-hat sound and the closed hi-hat sound.

When the process of step S908 is completed, the process proceeds to step S910, and it is determined whether GROUP is "1 (closed hi-hat or pedal hi-hat)". This judgment result is affirmative, that is, GROUP
If is “1”, the process proceeds to step S912.

In step S912, GROUP [VO
ICE] = “2 (open hi-hat)” voice is searched, and that voice is rapidly attenuated. Further, at this time, "0" is assigned to SFLG [VOICE] of the voice that is rapidly attenuated, to indicate that the voice is not sounding. When the process of step S912 ends, the process proceeds to step S906.

If the result of the determination in step S910 is negative, that is, if GROUP is "2", the process proceeds to step S906.

In step S906, SFLG [VOI
CE] is searched for a voice whose voice is “0” (voice that is not sounding). If there is a voice that is not sounding, the voice number is saved in VOICE.

When the process of step S906 is completed, the process proceeds to step S914, and it is determined whether or not a voice not sounded is found in step S906. If the result of this determination is negative, that is, if there is no voice that is not sounding, the flow advances to step S916 to rapidly attenuate the voice that is sounding at the lowest volume level, and save that voice number in VOICE. Further, at this time, "0" is assigned to SFLG [VOICE] of the voice that is rapidly attenuated, to indicate that the voice is not sounding. When the process of step S916 ends, the process proceeds to step S918.

If the result of the determination in step S914 is affirmative, that is, if there is a voice that is not sounding, the process proceeds to step S918.

In step S918, step S906
Alternatively, in step S916, "1" is set to SFLG [VOICE] of the voice number stored in VOICE to indicate that "voice is being generated", and GRPN [VOIC
[E] stores the group number of GROUP determined in step S904 or step S908, and IN
The instrument number determined in step S904 or step S908 and stored in INST1 is stored in STN [VOICE].

When the process of step S918 is completed, the process proceeds to step S920, the parameters necessary for generating the musical sound of INST1 are read from the ROM 14,
It is sent to the musical sound generator 32. For example, the musical sound generator 32
Actually sounds the open sound of the instrument number "3" set in INST1 at the volume level of the open sound in the hi-hat information table by the voice of the voice number stored in VOICE.

When the process of step S920 is completed, the process proceeds to step S922, and it is determined whether or not the instrument number of INST2 is "0". This judgment result is affirmative, that is, the INST2 instrument number is "0".
If so, the assigner sub routine is terminated. Therefore, in this case, only the musical sound of INST1 is produced.

On the other hand, if the determination result of step S922 is negative, that is, if the instrument number of INST2 is not "0" (in this case, INST is determined in step S908).
This is the case where the instrument number "4" is set to 2. ), The process proceeds to step S924.

At step S924, SFLG [VOI
CE] is searched for a voice whose voice is “0” (voice that is not sounding). If there is a voice that is not sounding, the voice number is saved in VOICE.

When the process of step S924 is completed, the process proceeds to step S926, and it is determined whether or not a voice not sounding is found in step S924. If the result of this determination is negative, that is, if there is no voice that is not sounding, the flow advances to step S928 to rapidly attenuate the voice that is sounding at the lowest volume level, and save that voice number in VOICE. Further, at this time, "0" is assigned to SFLG [VOICE] of the voice that is rapidly attenuated, to indicate that the voice is not sounding. When the process of step S928 ends, the process proceeds to step S930.

Also, if the determination result of step S926 is affirmative, that is, if there is a voice that is not sounding, the process proceeds to step S930.

In step S930, step S924
Alternatively, in step S928, "1" is set to SFLG [VOICE] of the voice number stored in VOICE to indicate that "sounding", and GRPN [VOIC
E] stores the group number of the GROUP determined in step S908, and INSTN [VOICE] stores the instrument number "4" stored in INST2 in step S908.

Upon completion of the processing in step S930, the flow advances to step S932 to read from the ROM 14 the parameters necessary to generate the musical sound of INST2,
It is sent to the musical sound generator 32. Then, the musical sound generator 32
Actually produces the close sound of the instrument number "4" set in INST2 at the volume level of the close sound of the hi-hat information table by the voice of the voice number stored in VOICE. Step S93
When the processing of 2 is completed, this assigner sub routine is completed.

Next, step S50 of the main routine.
The control signal processing of No. 8 will be described in detail based on the control signal processing sub-routine of FIG.

First, in step S1002, it is determined whether the control request flag CNTREQ is "1". If the result of this determination is negative, that is, if the control request flag CNTREQ is "0", then this control signal processing routine is terminated without performing any processing.

On the other hand, if the result of the determination in step S1002 is affirmative, that is, if the control request flag CNTREQ is set to "1", the flow advances to step S1004 to determine whether CNTRL is "0". . If the determination result is affirmative, that is, if the controller (foot pedal) is fully depressed and CNTRL is "0", the process proceeds to step S1006 and TRGN is set to "0".
Is substituted. When the process of step S1006 ends,
It proceeds to step S1008.

In step S1008, the musical sound generating section 32 is controlled to generate a musical sound based on the assigner sub routine shown in FIG.

When the processing of step S1008 is completed,
The process proceeds to step S1010, the trigger information table is searched, and TRGN is transmitted from the MIDI signal output terminal 28.
The note number of the MIDI signal corresponding to is determined.

When the processing of step S1010 is completed,
In step S1012, the MIDI signal indicating the note number determined in step S1010 is set to MIDI
Write to send buffer.

When the processing of step S1012 is completed,
In step S1014, MI is determined from the value of CNTRL.
Determines the DI signal control change value. In the present embodiment, it is determined by the calculation of “CNTRL × 127/15”.

When the processing of step S1014 is completed,
In step S1016, the MIDI signal indicating the control change determined in step S1014 is set to M
Write to IDI send buffer.

When the processing of step S1016 is completed,
In step S1018, the hi-hat information table is searched from CNTRL, and the volume level of the open hi-hat sound and the closed hi-hat sound, decay, GRO
Determine UP.

When the processing of step S1018 is completed,
In step S1020, the voice that is producing the open hi-hat tone is detected, and the high-hat tone that is being produced is controlled by retransmitting the volume level and the decay.

Also, the voice number VOI at that time
From CE, GROUP is substituted into GRPN [VOICE].

When the processing of step S1020 is completed,
In step S1022, the voice that is producing the closed hi-hat tone is detected, and the high-hat tone that is being produced is controlled by retransmitting the volume level and the decay.

The voice number VOI at that time
From CE, GROUP is substituted into GRPN [VOICE].

When the processing of step S1022 is completed,
In step S1024, "0" is assigned to CNTREQ, and this control signal processing sub-routine is ended.

Therefore, in step S1020 and step S1022 described above, the group number of each voice is updated to the group corresponding to the value of CNTRL, so that the hi-hat sound produced in the group "1" is reproduced. , By operating the controller, "CNTR
After changing to the hi-hat sound of "L = 8 to CNTRL = 15", "CNTRL = 8 to CNTRL = 1 again.
Even when the hi-hat sound is generated at "5", the operation of the controller causes "CNTRL = 8 to CNTRL = 1".
Since the hi-hat sound of the group "1" which is being generated and is changed to "5" is not muted in step S912, the open hi-hat sound does not give a feeling of being interrupted.

For example, by hitting the pad 3 with "CNTRL = 5 (group" 1 ")", a hi-hat sound is produced, and the hi-hat sound being produced is changed to "CNTRL = 11" by operating the controller. Further, a case where the pad 3 is hit again with "CNTRL = 11" will be described.

In this case, the group of hi-hat sounds being sounded with "CNTRL = 5 (group" 1 ")" is determined in steps S1020 and S1022.
It will be updated to the group “2” corresponding to “CNTRL = 11”. Therefore, "CNTRL = 11" again
When the pad 3 is hit with, the determination result of step S910 is negative, and the voice being sounded is not rapidly attenuated.

Next, the MIDI signal input from the MIDI signal input terminal 26 has a note number "42", "44" or "46" for producing a hi-hat sound.
The hi-hat sound control sub-routine executed in the case of the above is described based on the flowchart shown in FIG.

First, in step S1102, MI
Based on the value of the control change information of the DI signal, the control signal = (value of control change information) × 15/127 is executed to obtain the control signal CNTRL.

When the processing of step S1102 is completed,
In step S1104, the hi-hat information table is searched from the control signal, and the volume level of the open hi-hat sound and the closed hi-hat sound, the decay,
Determine the GROUP.

When the processing of step S1104 is completed,
In step S1106, the voice that is producing the open hi-hat sound is detected, and the high-hat sound that is being produced is controlled by retransmitting the volume level and the decay.

The voice number VOI at that time
From CE, GROUP is substituted into GRPN [VOICE].

When the processing of step S1106 is completed,
In step S1108, the voice that is producing the closed hi-hat sound is detected, and the high-hat sound that is being produced is controlled by retransmitting the volume level and the decay.

Also, the voice number VOI at that time
From CE, GROUP is substituted into GRPN [VOICE], and the hi-hat sound control routine ends.

The trigger information table and the hi-hat information table may be stored in the RAM 16 instead of the ROM 14 so that the performer can arbitrarily set them.
