2. Description of the Related Art Recent electronic musical instruments simulate various sounds of various musical instruments such as guitar choking, violin vibrato, brass crescendo, etc. by using operators such as pitch bend, keyboard pressure, modulation wheel, and expression pedal. The ones that do are often used.

These operators assign functions to the wheels by, for example, the ten-key function of the keyboard, and when the wheels are subsequently operated, the pitch, tone color, volume, etc. continuously change according to the operation of the wheels. Such conventional control by the operator is suitable for continuously changing the timbre, volume, etc. between performances.

In the conventional function allocation to the wheel, the switch for instructing the wheel allocation is operated to enable the code input of the function to be allocated to the wheel, and when the code is input from the ten-key pad, The wheel is configured so that the set value of the function can be input.

The relationship between the function that can be assigned to the wheel and the code for instructing the assignment of the function is usually pasted and displayed on the keyboard. However, because the list of functions attached to this keyboard has many items, the display of characters is generally small and difficult to see,
It is also difficult to remember.

Further, in assigning the function, it was troublesome to enter the code indicating each function accurately with the ten keys.

Moreover, since the conventional electronic musical instrument does not have a display function for indicating the kind of the set function and the setting status of the set value in the function, it is easy to make a mistake, and the setting status cannot be confirmed without playing. There was a problem and improvement was required.

In addition, there is a method of setting using an editor, but this method requires operating the editor and sequentially resetting it in accordance with the tree structure of the editor, which is complicated in operation and switching time. Not suitable for switching between.

When confirmed, 007 indicates the volume code, and when the specific key to which the volume is assigned is pressed, the code number 007 is input internally as in the case of input from the numeric keypad. This is because

Next, the operation of this embodiment having the above configuration will be described with reference to the flow chart. In addition,
In the present embodiment, description will be made assuming that the setting value of each function is input through the ten-key after the specific key is pressed to assign the function.

FIG. 5 is a flow chart showing the overall processing of the electronic musical instrument in this embodiment. Initialization processing of the electronic musical instrument is performed by a reset signal generated by turning on the power or pressing a reset switch (not shown) (step S1).

In this initial setting process, the internal state of the tone signal generator 5 is set to the initial state to prevent unnecessary sounds from being generated when the power is turned on, and the work area of the RAM 12 is cleared. This is processing for initializing data such as registers, flags, volume, and timbre. The initialization process will be described in detail with reference to FIG.

Next, panel processing is performed (step S
2). This is processing such as switching a tone color from a piano to a guitar or switching a volume according to the setting of the panel switch.

When assigning a function to the numeric keypad or the wheel 36 of the present invention by pressing a specific key, the KYBDSW provided on the operation panel 3 is pressed. The panel processing will be described in detail with reference to FIGS.

Next, keyboard processing is performed (step S
3). In this keyboard processing, data associated with key depression / key release of the keyboard 1 is loaded into the RAM 12 and stored therein. This stored data is used in the key-on processing and the function assignment to the ten keys and the wheel 36 of the present invention which will be performed later. The details of the operation of the keyboard processing will be described with reference to FIG.

Next, wheel processing is performed (step S
4). The wheel processing is for detecting whether or not the wheel 36 is operated. When the wheel 36 is operated, the voltage for indicating the operation position is detected and a signal corresponding to the wheel operation is transmitted. Details will be described with reference to FIG.

Then, other processing is performed (step S5). In this "other processing", processing according to switch settings detected by panel processing, keyboard processing, wheel processing, etc., such as tone color and volume change processing, rhythm selection processing, sounding processing corresponding to key numbers, Mute processing is performed.

When the other processes in step S5 are completed, the process returns to step S2, and the same processes are repeated thereafter. As a result, functions are assigned according to the operation of the operation panel 3, and a desired performance is output by the electronic musical instrument.

The processing relating to MIDI, the processing relating to the timer, and the writing processing to the storage section are performed in the "other processing".

Next, with reference to FIG. 6, the operation of the portion of the initialization process shown in step S1 of FIG. 5 related to the present invention will be described.

In the initialization process, first, a mode flag (hereinafter referred to as MODFLG), a transmission channel base (hereinafter referred to as TXCHBAS), and a keyboard function (hereinafter referred to as KYBDFNC) are initialized (step S11).

The MODFLG is provided on the RAM 12 and is a flag indicating the currently set mode among the modes such as wheel assignment, keyboard mode, and tone color assignment.

In the initial value setting of step S11,
MODFLG is 0, that is, in normal mode, TXC
The HBAS is initialized to the 0th channel, and the KYBDFNC is initialized to the 0th, that is, the volume (VOL).

Then, the storage unit for storing the value input from the ten keys is initialized (step S12). The storage unit consists of three digits. VAL100N is the value of the tens digit, VAL010N is the value of the tens digit, and VAL001N.
Stores the numerical value of ones digit, and the value input from the ten-key is sequentially shifted to the upper digit, and is deleted when it exceeds three digits and overflows.

Next, the transmission key numbers (hereinafter referred to as TXKEYNO) of the MIDI signals for all the keys and the transmission completion flag,
Also, the memory for storing the transmission channel numbers (hereinafter, referred to as TXKEYCH) of MIDI signals for all keys is initialized (step S13).

TXKEYNO stores the key of which the key-on is transmitted, and TXKEYCH stores the channel of which the key-on is transmitted. This is, for example, with the keyboard 1 held down,
Even when the transmission channel can be switched, the off signal is transmitted on the channel that transmitted the key-on or octave shift.

The transmitted flag is a flag for setting the transmitted flag in advance so as to suppress the pronunciation because it does not need to be pronounced when the key is used as a ten-key pad, for example.

Then, other initialization processing is performed (step S14). This "other initialization process"
Then, PROG31, WHEEL32, KYBD33,
In addition to setting the set value of each switch such as CH + 34 and CH-35 to the initial value, processing other than the above which is not directly related to the present invention, such as MIDI output processing and memory writing processing, is performed.

Next, the operation of the panel processing in step S2 of the main routine will be described with reference to FIGS.

In the panel processing, first, the on / off state of each switch detected by the panel scan circuit 4 of the operation panel 3 and stored in a predetermined area of the RAM 12 is detected by the CPU.
10 is read.

Next, it is checked whether or not there is an on event in each panel switch provided on the operation panel 3 (step S21). This is to check the change in the setting state of the switch on the operation panel 3.

Here, if there is no event, there is no change in the setting of the pannel switch, so the flow branches directly to the main routine.

On the other hand, if it is determined in step S21 that there is an ON event, then it is checked whether or not the PROGSW 31 indicating the tone color change is turned on (step S22). This is done by examining the event map created by the panel scan process.

If it is determined that there is an event, there is a mode transition, so that 1 is first set in MODFLG (step S23), and then the numeric keypad is cleared (step S24). The ten-key clear will be described in detail with reference to FIG.

Further, the display 13 is currently displaying PROGSW3.
“PRG” indicating that 1 is pressed and the currently set tone color number are displayed (step S25), and the process returns to the main routine.

On the other hand, in step S22, PROGSW31
When is OFF, it is then checked whether or not the WHEELSW 32 is turned on (step S26).

When the WHEELSW 32 is turned on, the MODFLG is selected as in steps S23 to S25.
Is set to 1 (step S27), the numeric keypad is cleared (step S28), and "ASn" indicating that the wheel is currently set on the display 13 and wheel assignment indicating the function currently set on the wheel 36 are set. The number is displayed (step S29) and the process returns to the main routine.

On the other hand, in step S26, WHEELSW3
When 2 is off, it is then checked whether or not the KYBDSW 33 is on (step S30).

When KYBDSW 33 is turned on, 1 is set in MODFLG (step S3).
1) Further, the numeric keypad is cleared (step S3
2) The volume value currently set as "VoL" is displayed on the display 13 (step S33), and the process returns to the main routine.

On the other hand, in step S30, KYBDSW
When 33 is off, it is then checked whether or not CH + SW34 indicating the channel increment is turned on (step S34).

When CH + SW34 is turned on, 1 is added to TXCHBAS (step S3
5) It is checked whether the added value of TXCHBAS is larger than 16 (step S36).

This is a process of checking whether the assigned number of channels is within the predetermined number of channels because the number of channels of the musical instrument is 16 from 0 to 15. Therefore, if the number of assigned channels is within the predetermined number, the process directly branches to step S42.

On the other hand, when CH + SW34 is off,
Then, CH-SW3 indicating the decrement of the channel
It is checked whether or not 5 is turned on (step S3).
8).

Then, when the CH-SW 35 is turned on, 1 is subtracted from TXCHBAS (step S39), and it is checked whether the subtracted value of TXCHBAS is smaller than -1 (step S40). .

If the result is larger than -1, the assigned channel is within the predetermined range (0 to 15), and the process directly branches to step S42. On the other hand, -1
If it is smaller, the allocated channel is out of the predetermined range, and therefore the maximum value 15 of the number of channels is allocated to TXCHBAS (step S41).

Then, the assigned channel number and tone color number are displayed on the display 13 (step S4).
2) Return to the main routine.

On the other hand, when the CH-SW 35 is off, there is no change, so the process directly returns to the main routine.

Next, steps S24, S28, S in FIG.
The operation of the ten key clearing process performed at 32 will be described with reference to FIG.

The ten-key clearing process is a process for initializing the ten-key, and in the ten-key clearing process, first, the memory KETA for storing the number of digits of the currently input numerical value.
0 is set to 10K (step S51).

Then, a memory for storing the input numerical value for each digit, VAL100N, VAL010N, VA.
Initialize by storing 0 in L001N (step S5
2) Return to the panel processing routine.

In the present invention, the memory for storing the value input by the numeric keypad is prepared for three digits, and the input value is first stored in the memory VAL001N showing the first digit and the next numerical value is input. Then, the memory VAL00 has already been
The value stored in 1N is incremented by one digit and stored in memory V
It is stored in AL010N.

Similarly, each time a new numerical value is input, it is incremented by one digit and the overflow of three digits is sequentially discarded.

Next, the operation of the keyboard processing in step S3 of the main routine will be described with reference to FIG.

In the keyboard processing, it is first checked whether or not there is a key event (step S61). That is, CP
By checking the old and new event key buffers provided in the RAM 12 by the U 10, it is possible to check whether or not there is a key event. As a result, if there is no key event, there is no need for keyboard processing, and the process returns to the main routine.

On the other hand, when it is determined that there is a key event, the number of the key having the key event is stored in the memory KEYNO provided for each key (step S62).

Then, it is checked whether the key event stored in KEYNO is an ON event (step S63). As a result, if it is an on event, the key-on process is performed (step S64), and if it is an off-event, the key-off process is performed (step S65).

The operation of the key-on process is shown in FIG.
1 and the operation of the key-off process will be described in detail with reference to FIG.

Next, the key-on process performed in step S64 of the keyboard process will be described with reference to FIG.

In the key-on processing, it is first checked whether or not the mode flag MODFLG is 0 (step S71). This is a process for checking whether or not it is a normal performance mode, because the normal performance mode is assigned to 0 of MODFLG.

As a result, if MODFLG is 0, it means that the performance is a normal performance mode in which all keys are used for performance. Therefore, the "normal key-on process" (step S72) is performed and the process returns to the main routine. Note that "normal key-on processing"
This will be described in detail with reference to FIG.

On the other hand, if MODFLG is not 0, then the key number KEYNO of the pressed key is 24≤.
It is checked whether or not it is within the range of KEYNO ≦ 33 (step S73). This is a process for checking whether the ten-key has been operated. If the ten-key has been operated, the "numeral Key process" (step S74) is performed, and the process returns to the keyboard processing routine.

The "numerical key processing" is shown in FIG.
It will be described in detail in Section 3. Further, in the present embodiment, it is assumed that the ten keys are assigned to the key numbers 24 to 33.

On the other hand, if the ten key is not operated in step S73, it is checked whether or not the clear key [Clr] for performing the canceling process is pressed (step S75). This process is the KEYNO of the key that is turned on.
Is checked by checking whether it is 34 assigned to the clear processing.

In the case of the clear processing, the ten-key clear key processing is subsequently performed (step S76), and the process returns to the keyboard processing routine. The clear key processing will be described in detail with reference to FIG.

On the other hand, if it is not the clear processing in the above step S75, it is subsequently checked whether or not the enter key [Ent] for executing the confirmation processing is pressed (step S77). This process turns on the key KEYNO
This is done by checking whether the enter key is assigned 35.

When the key number of the pressed key is 35, the enter key processing is performed, so "enter key processing" is performed.
(Step S78) is performed, and the process returns to the keyboard processing routine.
It should be noted that the "enter key processing" will be described with reference to FIGS.
Will be described in detail.

On the other hand, if the enter key has not been pressed, it is subsequently checked whether or not the exit key [Exit] has been pressed (step S79). This process is a process for transitioning from the function assignment mode to the normal performance mode, and is performed by checking whether the key KEYNO of the turned-on key is the key number 36 to which the exit is assigned.

If the key number of the pressed key is 36, it means "exit key processing", so "exit key processing" (step S80) is executed and the process returns to the keyboard processing routine. For "Exit Key Processing", refer to Fig. 1.
This will be described in detail in Section 8.

On the other hand, if the exit key has not been pressed, it is subsequently checked whether or not the volume key has been pressed (step S81). This processing is performed by checking whether the key number of the turned-on key is the key number 1 to which the volume is assigned.

When the key number of the pressed key is 1, the "volume key process" (step S82) is performed, and the process returns to the keyboard process routine. In addition, "Volume Ke
The "y process" will be described in detail with reference to FIG.

On the other hand, if the volume key is not pressed, it is subsequently checked whether or not the expression key [Exp] is pressed (step S83). This processing is performed by checking whether the KEYNO of the turned-on key is the key number 3 to which the expression is assigned.

If the key number of the pressed key is 3, it means that the expression key processing is "Exp".
Key processing "(step S84), and the process returns to the keyboard processing routine. The "Exp Key processing" will be described in detail with reference to FIG.

On the other hand, if the expression key has not been pressed, it is subsequently checked whether or not the pan pot key [Pan] has been pressed (step S85). This processing is performed by checking whether the key KEYNO of the turned-on key is the key number 6 assigned to the pan pot.

If the key number of the pressed key is 6, it means the panpot key process, so the "PanKey process" (step S86) is executed and the process returns to the keyboard process routine. The "PanKey processing" will be described in detail with reference to FIG.

On the other hand, if the pan pot key has not been pressed, it is subsequently checked whether or not the reverb key (Rev) has been pressed (step S87). This processing is performed by checking whether the key number of the turned-on key is the key number 8 to which the reverb is assigned.

If the key number of the pressed key is 8, the reverb key processing is in effect, so "RevKey processing" is performed.
(Step S88) is performed, and the process returns to the keyboard processing routine.
The "RevKey process" will be described in detail with reference to FIG.

On the other hand, if the reverb key has not been pressed, it is subsequently checked whether or not the cola ski [Chor] has been pressed (step S89). This processing is performed by checking whether the key number of the turned-on key is the key number 10 to which the reverb is assigned.

If the key number of the pressed key is 10, it means "ChoKey process" because it is a Cola-ski process.
(Step S86) is performed, and the process returns to the keyboard processing routine.
The "ChoKey process" will be described in detail with reference to FIG.

If the cola ski is not pressed in step S89, no processing is necessary, and the process directly returns to the keyboard processing routine.

Next, the "normal key-on processing" for performing MIDI output will be described with reference to FIG. This "normal key-on process" is a process for transmitting a key-off signal on the channel that has transmitted the signal indicating that the key has been turned on.

In the "normal key-on process", the transmission channel that transmitted the signal of the key-on key is stored for each key (step S91).

Then, the key number for transmitting the key-on is stored for each key (step S92). At this time, K
The reason why EYNO + 36 is carried out is that the 0th inside the electronic musical instrument corresponds to the 36th in MIDI, so that a predetermined raising is performed. The octave shift is omitted in this embodiment.

In 80H, since bit 7 is empty, bit 7 is used for the transmitted flag. The transmitted flag is set by taking or of KEYNO + 36 and 80H.

Then, the key-on of the key number (KEYNO + 36) is transmitted to the TXCHBASch of MIDI (step S93). This is a process of outputting a key-on by MIDI, and transmits the value of KEYNO + 36 to the channel designated by the transmission channel.

Next, with reference to FIG. 13, description will be given of [Numeric Key Processing] in step S74 of [Key-on Processing] in FIG.

In the [Numeric Key Processing], first, each time a numeral is input from the ten-key pad, a carry is carried out successively, and the input numeral is fetched for each digit (step S).
111). KEYNO-24 is because the key number KEYNO-24 of the pressed key is 0 on the numeric keypad.

It is to be noted that, when a new numeral is inputted and carried to a digit, the numeral which becomes 4 digits or more and overflows is sequentially cut off, and the latest 3 digits are always taken in.

Next, since one new numeral has been fetched in step S111, 1 is added to the memory KETA10K indicating the number of digits of the numeral currently input (step S112).

Next, the number of digits currently set KETA
It is checked whether 10K is greater than 4 (step S
113). This is because, in this embodiment, up to 3 digits are used as significant figures.

As a result, as a result of the determination in step S113, if the number of digits is 4 or more, the memory KETA indicating the number of digits is displayed.
Set 3 indicating 3 digits to 10K (step S11)

Next, the currently input state is displayed in a blinking manner in the display manner illustrated in FIG. 3, and the process returns to the [key-on processing] routine.

Next, the [clear key process] of step S76 of the [key-on process] of FIG. 11 will be described with reference to FIG. Incidentally, the [clear key processing] is processing for clearing and re-inputting at a stage where an input error has been made but it is still undecided.

In the [clear key processing], first, the ten key is cleared (step S121). The operation of the ten-key clearing process is the same as the ten-key clearing process described in detail with reference to FIG.

Then, the process of returning the screen mode to the initial setting value is performed. Therefore, it is first checked whether or not MODFLG is 1 (step S122).

When MODFLG is 1, it means that the program mode is to change the tone color. Therefore, [PRG] indicating the program mode and the currently set tone color number are displayed (step S123), and the [Key-on processing〕
Return to routine.

On the other hand, if MODFLG is not 1, then it is checked whether MODFLG is 2 (step S124).

When MODFLG is 2, it indicates the wheel allocation mode of the conventional function, and therefore the display 13 indicates the mode of function allocation to the wheel 36 [A
Sn] and the function number assigned to the wheel 36 are displayed (step S125), and the process returns to the [key-on process] routine.

On the other hand, if MODFLG is not 2, then it is checked whether KYBDFLG is 0 (step S126).

When KYBDFLG is 0, the volume changing mode is in effect, and therefore [VoL] indicating the volume changing mode and the currently set volume value are displayed (step S127). Key-on processing] Return to the routine.

On the other hand, when KYBDFLG is not 0,
Then, it is checked whether KYBDFLG is 1 (step S128).

When KYBDFLG is 1, the expression change mode is in effect. Therefore, [Exp] indicating the expression change mode and the current expression set value are displayed on the display unit 13 (step S129), and [Key-on Processing] Return to the routine.

On the other hand, if KYBDFLG is not 1,
Then, it is checked whether KYBDFLG is 2 (step S130).

When KYBDFLG is 2, the panpot change mode is in effect, so [Pan] indicating the panpot change mode and the currently set panpot value are displayed on the display 13 (step S131). ), And returns to the [key-on processing] routine.

On the other hand, when KYBDFLG is not 2,
Then, it is checked whether or not KYBDFLG is 3 (step S132).

When KYBDFLG is 3, it means that the reverb change mode is set. Therefore, [Rev] indicating the reverb change mode and the currently set reverb value are displayed on the display 13 (step S133). Key-on processing] Return to the routine.

On the other hand, when KYBDFLG is not 3,
Then, it is checked whether KYBDFLG is 4 (step S134).

When KYBDFLG is 4, the chorus change mode is in effect. Therefore, [Cho] indicating the chorus change mode and the currently set chorus value are displayed on the display 13 (step S135). Key-on processing] Return to the routine.

On the other hand, when KYBDFLG is not 4,
Since there is no corresponding clear process, the process directly returns to the [key-on process] routine.

Next, referring to FIGS. 15 to 17, in step S78 of [Key-on processing] of FIG. 11, [EntK
ey process] will be described. In addition, the [EntKey
[Process] is a process for confirming the input data.

In [EntKey processing], first,
It is checked whether or not KETA10K = 0 (step S1).
41). This is a process for checking the number of digits input with the ten-key pad. If it is 0, no numerical value has been input, so the process returns to the [key-on process] routine.

On the other hand, if the numeric keypad has been input, then the value input to the memory VAL is fetched (step S142). At this time, the number of the memory VAL100N that stores the value of the hundreds digit is multiplied by 100, and the number of the memory VAL010N that stores the value of the tenth digit is multiplied by 10, and these and the value of the ones digit are multiplied. The numbers in the stored memory VAL001N are added to generate a 3-digit number.

Subsequently, it is checked whether MODFLG is 1 (step S143). If MODFLG is 1, it means that the mode is the tone color number setting mode. Therefore, it is checked whether the numerical value input by the ten keys is within the proper range (step S144).

If it is out of the proper value range, that is, if the input numerical value is out of the range of 1 to 128, the process branches to step S177 to clear the ten keys and prepare for re-input.

On the other hand, if the numerical value input by the ten-key is within the proper value range, the value input by the ten-key, that is, VAL is taken into the memory of the tone color number (step S1).

If the volume value input with the ten-key pad is outside the proper value range, that is, outside the range of 0 to 127, the reverb value cannot be set. Is prepared.

On the other hand, if the numerical value input by the ten-key pad is within the proper reverb value range, the value VAL input by the ten-key pad is taken into the reverb value memory (step S
169), and the reverb value newly set to MIDI is output (step S170).

Further, [Rev] indicating that the reverb value is set is displayed on the display unit 13 and the set reverb value is displayed (step S171). Then, the process branches to step S177 to clear the ten key, and the next key is cleared. Input is prepared.

On the other hand, in step S167, KYBDF
If NC is not 3, then it is checked whether KYBDFNC is 4 (step S172). KYB
If the DFNC is 4, it is the setting of the chorus value.
Then, it is checked whether or not the numerical value input by the ten keys is within the proper chorus value range (step S173).

If the chorus value input on the ten-key pad is out of the proper value range, that is, outside the range of 0 to 127, the chorus value cannot be set. Is prepared.

On the other hand, if the numerical value input with the ten-key pad is within the proper range of the chorus value, the value VAL input with the ten-key pad is taken into the memory of the chorus value (step S
174), the newly set chorus value for MIDI is output (step S175).

Further, [Cho] indicating that the chorus value is set is displayed on the display unit 13, and the set chorus value is displayed (step S176). Then, the process branches to step S177 to clear the numeric keypad, and the next key is cleared. Input is prepared.

If KYBDFNC is not 4 in step S172, it means that there is no function assignment.
The process proceeds directly to step S177 to clear the ten keys (step S177) and returns to the [key-on process] routine.

Next, the exit key processing of step S80 of [key-on processing] will be described with reference to FIG. The mode of the exit key process is a process of returning from a function assignment mode such as tone color setting and wheel assignment to a normal performance mode.

In the exit process, first the MODF

Next, the numeric keypad is cleared (step S
193). This is a process of clearing the numeric keypad in advance because the volume value to be set is input later using the numeric keypad. The processing for clearing the ten keys is the same as the operation shown in FIG.

Further, the display 13 displays [VoL] indicating volume processing and the currently set volume value (step S194), and returns to [key-on processing].

[0209] On the other hand, in step S191, MODFL
If G is not 3, it is then checked whether MODFLG is 2 (step S195). This is a process of checking whether or not the function allocation mode is based on the conventional ten-key input.

When MODFLG is 2, it is the mode in which the function is assigned to the wheel 36 by the conventional ten-key input, so that 7 indicating that the function assigned to the wheel 36 is the volume is input by the ten-key (step S196). .

As a result, VAL100N and VAL
010N is set to 0, VAL001N is set to 7, and KETA10K is set to 1.

Next, the display 13 indicates that the function assigned to the wheel 36 is the volume [A

The operation for processing is the same as that in the case of the volume key processing or the expression key processing, and the description thereof will be omitted.

Next, the operation of the wheel processing described in step S4 of FIG. 5 will be described with reference to FIG.

In the wheel processing, it is first checked whether or not the wheel value has changed (step S25).
1). This is detected by the control unit of the CPU 10 comparing the wheel value read last time with the wheel value read this time.

When the wheel value does not change as a result of the detection, it is not necessary to perform the wheel processing, and the process directly returns to the main routine.

On the other hand, if the wheel value has changed,
The value of the function that assigned the read value to the wheel 36,
For example, it is output to MIDI as a tone color value or a reverb value (step S252), and the process returns to the main routine.

In this embodiment, when a specific key is pressed to assign a function, the setting value for each function is input using the wheel 36. You may comprise so that a setting value may be input with a ten-key pad.

FIG. 25 is a diagram for explaining the operation of the "key-off process" in step S65 of FIG. The "key-off process" is a process for transmitting the key-off on the transmission channel that transmitted the key-on.

In the "key-off process", first, the transmitted flag is checked (step S10).

This is done by checking whether bit 7 of EYNO] is 1 or not.

When the transmitted flag is already transmitted, the process shown in FIG.
The key-off is transmitted through the channel set in the [key-on process] of step S64 of 0 (step S102), and the process returns to the keyboard process routine. On the other hand, if the bit 7 is 0, the key-on has not been transmitted, and the process directly returns to the keyboard processing routine.

In this embodiment, the case where the wheel 36 is used as the continuously variable operator has been described as an example, but the present invention is not limited to this, and other operators may be used.

Further, in the present embodiment, the set value of each function when the specific key is pressed to assign the function has been described by taking the case of inputting using the ten keys as an example. You may comprise so that it may input using another continuously variable operator.
