BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an electronic musical instrument parameter setting apparatus according to an embodiment of the present invention. FIG. 1 is a functional configuration diagram showing a schematic configuration of a parameter setting device for an electronic musical instrument according to the present invention.

As shown in FIG. 1, an electronic musical instrument parameter setting apparatus according to the present embodiment includes an operation panel section 1, an operation state detection section 2, a parameter value calculation section 3, parameter value setting means 4, a parameter value storage memory. 5.

The operation panel section 1 is provided with various operators for controlling various functions provided in the electronic musical instrument, and includes an addition operator 1a and a subtraction operator. 1b is provided. Further, a first counter 12a and a second counter 12b are controlled by a CPU described later.
The counters 12a and 12b improve the operability of the adding operator 1a and the second operation state detecting means 2b.

The operation state detecting section 2 is provided for detecting a state in which each of the operators 1a and 1b provided on the operation panel section 1 is operated. Further, the parameter value calculation unit 3 performs a calculation for changing a setting parameter value such as a tone color, a tempo, or a tuning function according to the operation state of each of the operators 1a and 1b provided on the operation panel unit 1. It is provided in.

The parameter value setting means 4 reads the parameter value stored in the parameter value storage memory 5 and supplies it to the parameter value calculation section 3 when the addition operator 1a or the subtraction operator 1b is operated. In addition, it is provided for storing the calculation result of the parameter value calculation unit 3 in the parameter value storage memory 5.

FIG. 2 is a block diagram more specifically showing the configuration of the parameter setting device for an electronic musical instrument according to the present invention.
As shown in FIG. 2, the circuit section of the parameter setting device of the electronic musical instrument according to the present embodiment includes a CPU connected by a bus 9.
12, a microcomputer comprising a ROM 11, a RAM 10. In addition, the parameter value storage memory 5 shown in FIG.

The CPU 12 realizes various functions based on a program stored in the ROM 11. The functions of the operation state detector 2, parameter value calculator 3, and parameter value setting means 4 shown in FIG.
2, a microcomputer comprising a ROM 11 and a RAM 10.

The tone generator 14 reads PCM sound source data from the ROM 11 based on the information detected by the operation state detector 2 and the event information of the keyboard 13, and processes the amplitude and envelope to perform D / A conversion. Output to the container 15. A tone signal obtained from the D / A converter 15 is supplied to a speaker 17 via an amplifier 16 and is generated.

FIG. 3 is a flowchart showing the operation procedure of the main processing of the parameter setting device for an electronic musical instrument according to the present embodiment. When the operation is started as shown in FIG. 3, first, an initialization process is performed in step P1. That is, when the power of the electronic musical instrument is turned on, the CPU 12 first performs an initial process and a tone generator (sound source).
, Initialization of the RAM 10, and the like.

Next, in step P2, a keyboard scanning process is performed. As a result, all the keys of the keyboard 13 are scanned, and the pressed key is detected. Then, the process proceeds to step P3 to determine whether or not the event is a key event.

When it is detected that the operated key is present, the process proceeds to step P4, and if the key event is for instructing sound generation, the read performance data is subjected to sound generation processing. If the key event in step P3 is data for instructing the silencing of the currently sounding tone, the corresponding tone is silenced.

Then, the program proceeds to a step P5, where other keyboard processing is performed, and thereafter, the flow shifts to a panel scan processing in a step P6. In the panel scan process of Step P6,
A process for sequentially checking the operation states of all the operators is performed. That is, a panel scan process for sequentially checking the operation states of all the operators on the operation panel unit 1 is performed, and in step P7, it is determined whether or not an SW event has occurred.

If the result of this determination is that there is an operator that has been turned on, the process proceeds to step P8, where it is determined whether the operated operator is a value SW. If the operated operator is a value SW, the process proceeds to step P9, and it is determined whether or not the operated value SW performs the tempo setting mode. Then, when the tempo setting mode is to be performed, the process proceeds to step P10 to set the tempo, and then proceeds to step P13.

On the other hand, if the result of determination in step P9 is that the tempo setting is not to be performed, the process proceeds to step P11, where other parameters are set.
Go to step 13. On the other hand, if the result of the determination in step P8 is that the operated operator is not a value SW, the process proceeds to step P12, performs other panel processing, and then proceeds to step P13.

In step P13, it is determined whether or not the automatic performance is on. If the automatic performance ON instruction has been issued, the process proceeds to step P14 to perform an automatic performance process, and then proceeds to step P15 to perform other processes. On the other hand, if the result of determination in step P13 is not automatic performance on, the flow directly proceeds to step P15 to perform other processing, and then loops to step P2.

FIG. 4 is a flowchart showing the procedure of the SW ON event process. As shown in FIG. 4, in the SW ON event, first, in steps P1 and P2, data is set in an automatic count standby timer and an automatic count interval timer.

These timers are provided in a timer processing section of the CPU. In the configuration diagram of FIG. 1, an automatic count standby timer is shown as a first counter 12a, and an automatic count interval timer is shown as a second counter 12a. As a counter 12b.

The first counter 12a is provided in order to prevent the user from immediately entering the process of holding down when the parameter value is to be changed by ± 1.
By adjusting the value set here, it is possible to adjust the time until the process of continuing to press is performed.

The second counter 12b is provided for adjusting an interval for increasing or decreasing the parameter value. That is, if the interval for increasing or decreasing the parameter value is performed at the timing of the timer, the rate at which the parameter value increases or decreases becomes too fast, and the parameter value cannot be set to a desired value. Therefore, in the present embodiment, the second counter 12b is provided, and by setting a predetermined value to the second counter 12b, the parameter value can be adjusted so that the increasing speed or the decreasing speed becomes an easy-to-operate speed. .

After setting a predetermined value in each of the counters 12a and 12b, the process proceeds to step P3. In step P3, the current parameter value held in the buffer is stored in the first register Ar, the upper limit value of the parameter value is set in the second register Br, and the parameter value is stored in the third register Cr. Set the lower limit.

The second and third registers Br, Cr
Can be made different depending on the type of parameter. Therefore, for example, the volume can be set as 0 to 100, and the tempo can be set as 0 to 250.

Then, the program proceeds to a step P4, wherein it is determined whether or not the second flag is set. When the addition operator 1a or the subtraction operator 1b is operated for the first time, since the second flag is not set, the process proceeds to step P7 to perform a process of adding +1 or a process of decreasing -1.

Then, the program proceeds to a step P8, in which a process for holding the parameter values stored in the first register Ar in the buffer is performed, and in a step P9, a process for setting the parameters is performed.

After that, the program shifts to step P10 to perform display processing after the parameter value is changed. Thereby, the operator can know how the parameter value has changed by operating the addition operator 1a or the subtraction operator 1b by monitoring the display unit.

Next, the program shifts to step P11 to perform processing for setting a second flag, and then returns. Thereafter, when the switch is continuously pressed, the process proceeds to the timer process shown in FIG. 5, and when the switch is stopped, the process proceeds to the switch-off event process shown in FIG.

In the timer process of FIG. 5, first, in step P1, it is determined whether or not a standby counter, that is, a first counter 12a is set. As a result of the above determination, if the first counter 12a is not set, the process returns. If the first counter 12a is set, the process proceeds to step P2 and the standby counter (the first counter 1)
It is determined whether the count value of 2a) is 0 or not.

If the result of this determination is that the count value is not 0, the process returns to step P5 after decrementing the count value. Also, as a result of the determination in step P2,
If the count value of the standby counter (first counter 12a) is 0, the process proceeds to step P3, where the automatic count interval timer count (second counter 1
After performing the process of decreasing the count value in 2b), it is determined whether or not the count value of the interval timer count is 0.

When the count value is not 0, the process returns. When the count value is 0, the process jumps to step P2 of the SW on event process shown in FIG. In the SW on event process of FIG. 4, the same process as the above-described process is performed in step P2 and the next step P3, and then the process proceeds to step P4. Step P
In the case of No. 4, it is determined whether or not the second flag is set in the same manner as before, but this time the second flag is set.
Since the flag has been set, the routine goes to Step P5.

In step P5, it is determined whether the parameter value stored in the first register Ar is a multiple of ten. If the result of this determination is that the parameter value stored in the first register Ar is not a multiple of 10, the process proceeds to step P7, where the processing of +1 or -1 is performed as described above.

If the result of determination in step P5 is that the parameter value stored in the first register Ar is a multiple of 10, the process proceeds to step P6, where the parameter value stored in the first register Ar is stored. A process for increasing the parameter value by +10 or a process for decreasing the parameter value by 10 is performed. After performing such calculations, the following steps P9 to P1
Proceed to step 1 to perform the same processing as described above. The change of the parameter value is performed within the range of the upper limit value and the lower limit value set in step P3 described above.

On the other hand, in the SW off event processing of FIG. 6, first, in step P1, the count value of the automatic count standby timer is set to "FF" and reset. Next, the process shifts to step P2 to reset the second flag, and then returns.

The parameter setting device for an electronic musical instrument according to the present embodiment adjusts the parameter value as described above, so that after the parameter value becomes a multiple of 10,
The parameter value can be changed by 10 and a desired set value can be quickly called. In addition, such a function can be realized by a simple and inexpensive device.
