[0013]
The indicator unit 3 displays various states relating to display of various parameter setting states of the operator group 1, registration advance notice display and call start display, registration hold display, and the like.
[0014]
Next, the CPU 4 generates various control signals based on the program stored in the ROM 5, the parameter setting state, and the registration setting state to perform automatic performance execution processing and registration execution processing. Sound generation control is performed on the generator 7.
[0015]
The ROM 5 is a storage device that stores a series of programs for the CPU 4 to execute processing of various functions and a plurality of automatic performances or music data of automatic performances.
[0016]
The RAM 6 is a work memory that temporarily stores parameters, timers, and counters related to registration and the like when the CPU 4 executes program processing.
[0017]
The tone generator 7 has a waveform memory for generating a tone, generates a tone signal corresponding to music data supplied from the ROM 5 based on a control signal generated by the CPU 4, and converts the digital tone signal into an analog signal. After converting to a waveform signal and filtering processing such as removing unnecessary noise, the analog waveform signal is amplified by an amplifier and emitted from a speaker.
[0018]
FIG. 2 shows the configuration of the registration setting area in the 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 “hold 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 “memory bank area” is an area for copying and storing parameters from the “current area” when performing registration, and “memory bank (1) memory bank (2),... Memory bank (n)”. Consists of.
[0019]
The “holding area” is an area for temporarily storing parameters related to the registration when the execution of the registration is put on hold, and “parameter (1), parameter (2),. Stored.
The role of this “holding area” is that when a user presses a hold button (not shown) before calling a parameter by registration in the middle of calling an automatic musical piece, the parameter to be called is When the store button is temporarily stored in the “hold area” and this hold button is pressed again in the course of the automatic performance, the parameters are called from the “hold area” to the “current area” and reflected in the generation of the musical sound.
[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 registration call time of parameters is recorded, and the “parameter area” includes “parameter (1), parameter (2),... “” Is stored.
[0021]
FIG. 4 shows a memory configuration of automatic performance music data stored in the ROM 5.

Automatic performance music data (n)”, and “automatic performance music data” is note on / off, velocity. “Event (1), event (2)...” And data “Time (1), Time (2)...” Are stored.
[0022]
FIG. 5 shows a main flowchart of the present invention.
In S501, when a power switch (not shown) provided in the operator group 1 is turned on, the CPU 4 executes the initialization process of S501 in FIG. By this processing, the work memory in the RAM 6 is cleared, the timer and counter are reset, and each function is initialized.
[0023]
When the initialization process is completed, the process proceeds to S502 and the registration process is executed. Details of this registration process will be described later.
After the registration process is completed, the keyboard process of S503 is executed in accordance with the key pressing / release operation by the user, and then the automatic performance process of S504 is executed. Details of this automatic performance processing will be described later.
[0024]
Next, the parameter setting process of S505 is executed. Details of the parameter setting process will be described later.
Following the parameter setting process, other processes in S506 are executed, and the process returns to the registration process in S502 again. Until the power switch is turned off, the registration process, keyboard process, automatic performance process, parameter setting process, etc. Repeat the process.
[0025]
6 and 7 show detailed flowcharts of the registration process of S502 in FIG.
First, the CPU 4 determines whether or not a memory bank SW (not shown) provided in the operator group 1 is operated in the process of S601.
If the memory bank SW has been operated, the process proceeds to S602, the memory bank number for which 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 is not performed in the process of S601, the process proceeds to the process of S603 without executing the process of S602.
In step S603, the CPU 4 determines whether a memory SW (not shown) provided in the operator group 1 is in an “on” state.
In the determination of S603, if the memory SW is “ON”, the process proceeds to S604, the parameter stored in the current area is copied to the memory bank area corresponding to the register N, and the process proceeds to S605.
[0027]
On the other hand, if the memory SW is not in the “ON” state in the determination in S603, the process proceeds to S605 without executing the process in S604, and the mode SW (not shown) provided in the operator group 1 is “ It is determined whether or not it is in the “on” state.
[0028]
If the mode SW 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. Without executing, the process proceeds to the determination process of S607.
[0029]
The CPU 4 determines whether or not the call SW “not shown” provided in the operator group 1 in the process of S607 is in the “ON” state.
If the call SW is “ON” in the determination of S607, the process proceeds to S608. If the call SW is not “ON”, the process directly proceeds to S701 in FIG.
[0030]
In step S608, the CPU 4 determines whether the MODE flag is “0”. The MODE flag “0” indicates a normal mode and is a mode in which manual registration is executed.
The mode flag “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, the parameter in the memory bank corresponding to the register N is stored in the current area, and the process proceeds to S610, but the mode flag is “0”. If not, the process proceeds to S701 in FIG.
[0032]
Next, when the CPU 4 proceeds to the process of S610, the parameter stored in the current area is sent to the sound source provided in the musical tone generator 7, and the process proceeds to S701 of 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 the “on” state.
If the time setting SW is “ON”, the process proceeds to S702, and the TIME flag indicating the time setting mode is reversed, and then the process proceeds to S703.
[0034]
If the time setting SW is not in the “ON” state in the determination of S701, the CPU 4 proceeds to the process of S703 without executing S702.
Next, in step S703, the CPU 4 determines whether or not the time input SW for inputting the registration call start time provided in the operator group 1 is operated. If the time input SW is operated in the determination of S703, the process proceeds to S704, and it is determined whether or not the TIME flag is “1”. If the TIME flag is “1”, the time input by the time input SW in the process of S705 is stored in the memory bank corresponding to the register N, and the process proceeds to the next process of S706.
[0035]
On the other hand, if the TIME flag is not “1” in the determination in S704, it is not the registration time setting mode, and the process proceeds to S706 without performing the process in S705.
[0036]
Next, in the process of S706, the CPU 4 determines whether or not an SW (not shown) that holds the execution of registration provided in the operator group 1 is in the “on” state. If the hold SW is “ON” in this determination, the process proceeds to S707, and if the hold SW is not “ON”, this routine is terminated.
[0037]
Next, when the CPU 4 proceeds to the process of S707, it determines whether or not the MODE flag is “1”. If “1”, the CPU 4 executes the registration in the auto mode and shifts to the process of S708. .
On the other hand, if the MODE flag is “0”, the routine is terminated as it is in the normal mode.
[0038]
Then, when the CPU 4 proceeds to the process of S708, it determines whether or not the start flag STF is “1”. If the start flag STF is “1”, the process proceeds to S709 and the hold flag is reversed and the process proceeds to S710. If the start flag STF is “0”, the routine is terminated.
[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 CPU 4 proceeds to the process of S711, but if the hold flag is “0”. End this routine.
In step S711, it is determined whether there is data in the reserved area. If there is no data in the reserved area, this routine ends.
On the other hand, if there is data in the reserved area, the process proceeds to S712, and the parameters stored in the reserved area are copied to the current area, and the process proceeds to S713.
[0040]
Next, when the CPU 4 proceeds to the process of S713, it reads out the parameters stored in the current area and sends them to the sound source in the musical tone generator.
When the parameters have been sent to the sound source, the process proceeds to S714 to clear the reserved area, and the indicator section 3 turns off the on-hold indicator (not shown) and ends the routine.
[0041]
8, FIG. 9, and FIG. 10 are detailed flowcharts of the S504 automatic performance process in FIG.
The CPU 4 determines whether or not the START / STOP SW provided in the operator group 1 in the process of S801 is “ON”. When the START / STOP SW is turned “ON”, the process proceeds to S802, the start flag STF is inverted and the process proceeds to S803. If the START / STOP SW is not “ON”, S901 in FIG. Proceed to the process. It is determined whether or not the start flag STF is “1”.
In other words, the present embodiment is configured to execute the processing from S802 onward in FIG. 8 when the START / STOP SW is turned on, and to execute the processing from S901 in FIG. 9 when the START / STOP SW is not on. Yes.
[0042]
The CPU 4 inverts the start flag STF in the process of S802, and determines whether or not the inverted start flag STF is “1” in the next process of S803.
When the start flag STF is “0”, the sound source is instructed to mute the sound being generated (S809), the timer interrupt is prohibited (S810), the notice indicator and the hold indicator are turned off (S811), The reserved area is cleared (S812), and this routine is terminated.
[0043]
On the other hand, if the start flag STF is “1”, the process proceeds to S804, the address pointer is moved to the head of the automatic musical composition data, and then the process proceeds to S805.
In step S805, the automatic performance music data stored in the ROM 5 is read, and the process proceeds to step S806. The read automatic performance music data is an “event” indicating performance information such as pitch and velocity, or the pronunciation. It is determined whether it is “time” indicating time / silence time.
[0044]
In this determination, if the automatic musical piece data is “event”, this “event” is sent to the sound source (S807), the address pointer is advanced (S808), and the next automatic musical piece data is read. The process returns to S805.
On the other hand, if the read automatic performance music data is “time”, this “time” is written to the timer T1 (S813), then “0” is written to the timer T2 (S814), and the timer interrupt is prohibited. The state is canceled and the routine processing is terminated. (S815)
[0045]
When the timer interrupt prohibition state is canceled in step S815, the CPU 4 executes the interrupt processing 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 process of S813. (S1101)
Next, the process proceeds to S1102, and the timer T2 for which “0” is set in S814 is incremented to count the time until the registration call is started.
[0046]
Returning to the process of S801 in FIG. 8 again, if the START / STOP SW is not “ON”, the process proceeds to the process of S901 in FIG. 9 to determine whether or not the start flag STF is “1”. To 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”, this routine is terminated.
[0047]
The CPU 4 advances the address pointer if the timer T1 that has been decremented is “0” in the above-described timer interrupt processing in the determination of S902 (S903), and then reads the automatic performance music data indicated by this pointer (S904) It is determined whether the read automatic performance music data is “event” or “time”. (S905)
[0048]
If the automatic performance music data is “event” as determined in 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 musical piece data is “time” as determined in S905, this “time” is written in the timer T1 (S911), “1” is inserted in the counter n (S907), and the process proceeds to S908.
Similarly, if the timer T1 has not reached “0” in the determination in S902, the process proceeds to S907 and “1” is inserted into the counter n.
[0049]
Whether the value obtained by subtracting “predetermined time α” from “time of timer T2”, which has been incremented in the above-described timer interrupt process in the process of S908, has reached the time data of the memory bank corresponding to the counter n. Determine whether or not.
[0050]
This “predetermined time α” indicates a notice time for informing the user in advance of the registration change timing at the time of “α” before the time T2 when the registration call start time is set. is there.
[0051]
The CPU 4 proceeds to the processing of S912 to sequentially search which memory bank of the plurality of memory banks has reached the notice time “α” before the registration change timing time “T2”. Is incremented by 1 (S912), and it is compared whether or not the counter n exceeds the number of memory banks. (S913)
[0052]
If the counter n exceeds 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 still does not exceed the number of memory banks, returns to the process of S908 and changes 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, if the value obtained by subtracting “predetermined time α” from “time of timer T2” reaches the time data of the memory bank corresponding to the counter n in the determination of S908, is the hold flag set to “0”? Determine whether or not. (S909)
[0054]
If the hold flag is “0” in the determination in S909, the notice indicator is turned on (S910), and the process proceeds to S1001 in FIG. The process proceeds to S1001 in FIG. 10 without executing the process.
[0055]
When proceeding to the processing of S1001, the CPU 4 sets “1” to the counter n, and determines whether or not 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 1 in order to sequentially search which time data of the plurality of memory banks has reached the registration call time T2. To do. (S1007)
Then, it is determined whether or not the counter n exceeds the number of memory banks. (S1008) If the counter n exceeds the number of memory banks, this routine is terminated. If the counter n does not exceed 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 then whether or not the hold flag is “0” is determined. judge. (S1004)
[0058]
Returning to the process of S1004 again, if the hold flag is “0”, the parameter stored in the memory bank corresponding to the counter n is copied to the current area. (S1005)
Then, the parameters copied to the current area are sent to the sound source (S1006), and this routine is terminated.
[0059]
On the other hand, if the hold flag is “1” in S1004, the parameter stored in the memory bank corresponding to the counter n is copied to the “hold area” (S1009), and the hold indicator is lit ( S1010) and the routine is terminated.
[0060]
FIG. 12 shows 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 in the operator group 1 has been operated in the process of S1201.
[0061]
When the parameter setting SW is operated, the parameter stored in the current area is changed to a new parameter value set by the parameter setting SW. (S1202)
Then, the changed parameter value is sent to the sound source (S1203), and this routine is terminated.
On the other hand, if the parameter setting SW is not operated in the determination of S1201, this routine is terminated as it is.
[0062]
According to the present embodiment, when the keyboard performance is busy and there is no time to press the registration call button, or a beginner or the like cannot fully release the keyboard 2 with his hands full, and the hand can reach the registration button. Even if there is no room for extension, when the preset time has elapsed since the start of automatic performance, parameters are automatically called by registration. You can use the functions effectively.
[0063]
In addition, the present invention is not limited to the above-described embodiment, and can be implemented in various other forms in specific configurations, functions, operations, and effects without departing from the gist thereof.
For example, in the above embodiment, the registration call is performed with the “time” setting. However, as another registration call setting method, it may be set by the number of measures, the number of beats, or the like of the automatic performance song. . Although the registration call start timing is set at the same time as the start of the automatic performance, the registration call may be set in a standby state and started by pressing a key.
[0064]
