[0018]
FIG. 2 shows a configuration of a registration setting area in a work memory area in the RAM 6.
The work memory area in the RAM 6 is composed of a "current area", a "memory bank area", and a "reservation area". The "current area" is an area for storing various musical tone parameter groups used for generating musical tones. (1), parameter (2),... Parameter (n) "are stored.

The “reservation area” is an area for temporarily storing parameters related to the registration when the execution of the registration is suspended, and “parameter (1), parameter (2),... Parameter (n)” is Stored.
The role of the “hold area” is that if the user presses a hold button (not shown) in a hurry before the parameter is called by registration during the call of the automatic performance music, the parameter to be called is changed to “ If the hold button is pressed again during the automatic performance, the parameters are called from the "hold area" to the "current area" and reflected in the generation of musical tones.
[0020]
FIG. 3 shows a memory configuration of "memory bank (N)" in FIG.
The “memory bank (N)” is composed of a “parameter area” and “time data” in which a call start time of a parameter by registration is recorded. The “parameter area” includes “parameter (1), parameter (2),. "Is stored.

[0022]
FIG. 5 shows a main flowchart of the present invention.
In step S501, when a power switch (not shown) provided in the operator group 1 is turned on, the CPU 4 executes the initialization processing in step S501 in FIG. By this processing, the work memory in the RAM 6 is cleared, the timer and the counter are reset, and each function is initialized.
[0023]
Upon completion of the initialization processing, the flow advances to step S502 to execute a registration processing. Details of the registration process will be described later.
After the registration processing is completed, the keyboard processing of S503 is executed in accordance with the key press / key release operation by the user, and subsequently, the automatic performance processing of S504 is executed. Details of the automatic performance processing will be described later.
[0024]
Next, a parameter setting process of S505 is executed. Details of the parameter setting process will be described later.
Subsequent to the parameter setting process, other processes of S506 are executed, and the process returns to the registration process of S502 again. The registration process, the keyboard process, the automatic performance process, the parameter setting process, and the like are performed until the power switch is turned off. Is repeated.
[0025]
6 and 7 show detailed flowcharts of the registration processing in S502 in FIG.
First, in the process of S601, the CPU 4 determines whether or not a memory bank SW (not shown) provided in the operator group 1 is being operated.
If the memory bank SW has been operated, the process proceeds to S602, where the memory bank number for which the SW operation has been performed is stored in the register N, and the process proceeds to S603.
[0026]
On the other hand, if the memory bank SW operation has not been performed in the process of S601, the process shifts to the process of S603 without executing the process of S602.
When proceeding to the processing of S603, the CPU 4 determines whether or not a memory SW (not shown) provided in the operator group 1 is in an “ON” state.
If it is determined in step S603 that the memory SW is turned on, the process proceeds to step S604, in which the parameters stored in the current area are copied to the memory bank area corresponding to the register N, and the process proceeds to step S605.
[0027]
On the other hand, if the memory SW is not in the “ON” state in the determination of S603, the process proceeds to S605 without executing the process of S604, and the mode SW (not shown) provided in the operator group 1 is set to “ It is determined whether it is in the “ON” state.
[0028]
If the mode switch is "ON" in the determination of S605, the MODE flag is inverted in the process of S606, and the process proceeds to S607. If the mode SW is not "ON" in the determination of S605, the process of S606 is performed. The processing shifts to the determination processing of S607 without executing.
[0029]
The CPU 4 determines whether or not the calling SW “not shown” provided in the operator group 1 is in the “ON” state in the process of S607.
If it is determined in step S607 that the call SW is “ON”, the process proceeds to step S608. If the call SW is not “ON”, the process directly proceeds to step S701 in FIG.
[0030]
When proceeding to the processing of S608, the CPU 4 determines whether or not the MODE flag is “0”. When the MODE flag is "0", it indicates the normal mode and is a mode in which manual registration is executed.
The mode flag being "1" is a mode in which registration is automatically executed without manual operation.
[0031]
If the mode flag is "0" in this determination, the process proceeds to S609 to store the parameters in the memory bank corresponding to the register N in the current area and proceeds to the process of S610. If not, the process directly proceeds to the process of S701 in FIG.
[0032]
Next, when proceeding to the processing of S610, the CPU 4 sends out the parameters stored in the current area to a sound source provided inside the musical tone generating device 7, and proceeds to the processing of S701 in FIG.
[0033]
In the process of S701, the CPU 4 determines whether or not a registration time setting SW (not shown) provided in the operator group 1 is in an “ON” state.
If the time setting SW is “ON”, the process proceeds to S702, in which the TIME flag indicating the time setting mode is inverted, and then proceeds to the process of S703.
[0034]
If the time setting SW is not in the “ON” state in the determination of S701, the CPU 4 shifts to the processing of S703 without executing S702.
Next, in the processing of S703, the CPU 4 determines whether or not the time input SW for inputting the registration start time provided for the operator group 1 is operated. If it is determined in step S703 that the time input SW has been operated, the process advances to step S704 to determine whether the TIME flag is "1". Here, if the TIME flag is "1", the time input by the time input SW in the processing of S705 is stored in the memory bank corresponding to the register N, and the processing shifts to the next processing of S706.
[0035]
On the other hand, if the TIME flag is not “1” in the determination of S704, the process is not in the registration time setting mode, and the process proceeds to S706 without performing the process of S705.
[0036]
Next, in the process of S706, the CPU 4 determines whether or not a SW (not shown) for suspending the execution of the registration provided in the operator group 1 is in an “ON” state. In this determination, if the hold SW is "ON", the process proceeds to S707, and if the hold SW is not "ON", this routine is ended.
[0037]
Next, when proceeding to the processing of S707, the CPU 4 determines whether or not the MODE flag is “1”. If the MODE flag is “1”, the registration is executed in the auto mode, and the processing shifts to the processing of S708. .
On the other hand, if the MODE flag is "0", the routine is terminated because the mode is the normal mode.
[0038]
Then, when proceeding to the processing of S708, the CPU 4 determines whether or not the start flag STF is “1”. If the start flag STF is "1", the flow proceeds to the processing of S709, inverts the suspension flag, and proceeds to the processing of S710. If the start flag STF is "0", the routine is terminated as it is.
[0039]
Next, the CPU 4 determines whether or not the hold flag is “1” in the process of S710. If the hold flag is “1”, the process proceeds to the process of S711, but if the hold flag is “0”. If this routine ends.
Then, when the process proceeds to S711, it is determined whether there is data in the reserved area. If there is no data in the holding area, this routine ends.
On the other hand, if there is data in the reserved area, the process proceeds to step S712, where the parameters stored in the reserved area are copied to the current area, and the process proceeds to step S713.
[0040]
Next, when proceeding to the processing of S713, the CPU 4 reads out the parameters stored in the current area and sends out the parameters to the sound source in the tone generator.
When the parameters have been transmitted to the sound source, the process proceeds to step S714 to clear the reserved area, turn off the lit pending indicator (not shown) in the indicator unit 3, and terminate the routine.
[0041]
FIGS. 8, 9, and 10 show a detailed flowchart of the S504 automatic performance processing in FIG.
The CPU 4 determines whether or not the START / STOP SW provided for the operator group 1 has been turned on in the process of S801. When the start / stop switch is turned on, the process proceeds to step S802, inverts the start flag STF, and proceeds to step S803. If the start / stop switch is not turned on, step S901 in FIG. Proceed to processing. It is determined whether or not the start flag STF is “1”.
That is, in the present embodiment, when the START / STOP SW is turned on, the processing of S802 and subsequent steps in FIG. 8 is executed, and when it is not turned on, the processing of S901 and subsequent steps of FIG. 9 is executed. I have.
[0042]
The CPU 4 inverts the start flag STF in the processing of S802, and determines in the next processing of S803 whether or not the inverted start flag STF is “1”.
If the start flag STF is "0", the sound source is instructed to mute the tone being sounded (S809), the timer interrupt is prohibited (S810), and the notice indicator and the hold indicator are turned off (S811). The reservation area is cleared (S812) and the routine ends.
[0043]
On the other hand, if the start flag STF is "1", the flow advances to S804 to move the address pointer to the beginning of the automatic performance data, and then to the processing in S805.
Then, in step S805, the automatic performance music data stored in the ROM 5 is read out. In step S806, the read automatic performance music data is an "event" indicating performance information such as a pitch or velocity, or a sound. It is determined whether the time is “time” indicating time / silence time.
[0044]
In this determination, if the automatic performance music data is "event", this "event" is transmitted to the sound source (S807), the address pointer is advanced (S808), and the next automatic performance music data is read. It returns to the process of S805.
On the other hand, if the read automatic performance music data is "time", this "time" is written into the timer T1 (S813), and then "0" is written into the timer T2 (S814) to prohibit the timer interrupt. The state is released, and the processing of this routine ends. (S815)
[0045]
When the prohibition state of the timer interrupt is released in the process of S815, the CPU 4 executes the interrupt process flow shown in FIG. 11 at regular time intervals.
First, the timer T1 in which the "time" of the automatic performance music data is written is decremented in the processing of S813. (S1101)
Next, the process proceeds to S1102, in which the timer T2 in which "0" is set in the process of S814 is incremented to count the time until the registration call is started.
[0046]
Returning to the processing of S801 in FIG. 8 again, if the SW of START / STOP is not turned “ON”, the processing proceeds to the processing of S901 in FIG. 9, and it is determined whether or not the start flag STF is “1”. I do.
If the start flag STF is “1” in the determination of S901, the CPU 4 determines whether or not the timer T1 is “0” in the processing of S902. On the other hand, if the start flag STF is “0”, the routine ends.
[0047]
The CPU 4 advances the address pointer if the timer T1 that has been repeatedly decremented is "0" in the above-described timer interrupt processing in the determination of S902 (S903), and then reads out the automatic performance data indicated by this pointer. (S904), it is determined whether the read out automatic performance music data is “event” or “time”. (S905)
[0048]
If the automatic performance music data is "event" in the determination of S905, the CPU 4 sends the read "event" to the sound source (S906), and returns to the address pointer stepping process (S903) again. On the other hand, if the automatic performance data is “time” in the determination of S905, the “time” is written into the timer T1 (S911), “1” is inserted into the counter n (S907), and the process proceeds to S908.
Also, if the timer T1 has not reached “0” in the determination of S902, the process similarly proceeds to S907 and inserts “1” into the counter n.
[0049]
The CPU 4 determines whether the value obtained by subtracting the “predetermined time α” from the “timer T2 time” obtained by repeating the increment processing in the timer interrupt processing in the processing of S908 reaches the time data of the memory bank corresponding to the counter n. Determine whether or not.
[0050]
The “predetermined time α” indicates a notice time for notifying the user in advance of the timing of changing the registration at the time of “α” before the time T2 at which the registration call start time is set. is there.
[0051]
The CPU 4 proceeds to the process of S912 and proceeds to the process of S912 to sequentially search which of the plurality of memory banks has reached the notice time “α” prior to the registration change timing time “T2”. Is incremented by one (S912), and it is compared whether the counter n has exceeded the number of memory banks. (S913)
[0052]
If the counter n has exceeded the number of memory banks in the determination of S913, the CPU 4 proceeds to the process of S1001 in FIG. 10, but if the counter n has not exceeded the number of memory banks, returns to the process of S908 to change the registration. The search for the counter n corresponding to the memory bank that has reached the notice time “α” before the timing time “T2” is repeated.
[0053]
On the other hand, in the determination of S908, if the value obtained by subtracting the "predetermined time α" from the "timer T2 time" reaches the time data of the memory bank corresponding to the counter n, whether the hold flag is "0" Determine whether or not. (S909)
[0054]
In the determination of S909, if the hold flag is "0", the notice indicator is turned on (S910), and the process proceeds to S1001 in FIG. 10. If the hold flag is not "0" in the determination of S909, the process proceeds to S910. The process proceeds to S1001 in FIG. 10 without executing the process.
[0055]
Upon proceeding to the process of S1001, the CPU 4 sets “1” to the counter n, and determines whether the time data of the memory bank corresponding to the counter n is equal to the timer T2. (S1002)
[0056]
If the time data of the memory bank corresponding to the counter n is not equal to the timer T2, the counter n is incremented by one in order to sequentially search which of the plurality of memory banks has reached the registration calling time T2. I do. (S1007)
Then, it is determined whether or not the counter n has exceeded the number of memory banks (S1008). If the counter n has exceeded the number of memory banks, this routine ends. If the counter n has not yet exceeded the number of memory banks, the process of S1002 is performed again. Return to
[0057]
On the other hand, if the time data of the memory bank corresponding to the counter n is equal to the time of the timer T2 in this determination, the notice indicator is turned off (S1003), and it is determined whether or not the hold flag is “0”. judge. (S1004)
[0058]
Returning to the processing of S1004 again, if the hold flag is “0”, the parameters stored in the memory bank corresponding to the counter n are copied to the current area. (S1005)
Then, the parameters copied to the current area are transmitted to the sound source (S1006), and the routine ends.
[0059]
On the other hand, if the hold flag is “1” in the determination of S1004, the parameters stored in the memory bank corresponding to the counter n are copied to the “hold area” (S1009), and the hold indicator is turned on (S1009). S1010) and ends this routine.
[0060]
FIG. 12 is a detailed flowchart of the S505 parameter setting process in FIG.
The CPU 4 determines whether or not a parameter setting SW (not shown) provided for the operator group 1 has been operated in the process of S1201.
[0061]
When the parameter setting switch is operated, the parameter stored in the current area is changed to a new parameter value set by the parameter setting switch. (S1202)
Then, the changed parameter value is transmitted to the sound source (S1203), and the routine ends.
On the other hand, if the parameter setting switch has not been operated in the determination of S1201, the routine ends.
[0062]
According to the present embodiment, when the keyboard performance is busy and there is no time to press the registration call button, a beginner or the like cannot fully release the keyboard 2 due to his / her full keyboard performance. Even if there is no room to extend, the parameter call by registration is automatically performed at a preset time from the start of automatic performance, so that the tone generation form of the automatic performance song can be changed at the intended timing, and the registration The functions can be used effectively.
[0063]
In addition, the present invention is not limited to the above-described embodiment, and can be embodied in various other forms in a specific configuration, function, operation, and effect without departing from the gist thereof.
