Abstract

PURPOSE:To improve the setting efficiency by detecting an operation element being operated continuously up to the setting limit value of a parameter, further detecting the operation being carried on after the limit value is reached, and setting the set values of the parameters to mutually different values with the output. CONSTITUTION:When the operation element 20 is operated continuously to change the setting of a parameter, a limit operation detecting means 30 detects the operation reaching its limit value and an operation detecting means 31 detects the operation element being operated to normally vary the settings of a parameter setting device 32 as they are. The detecting means 30 sends the output signal to the operation detecting means 31 to detect the operation state of the operation element 2 when the detecting means 30 detects the limit value of the setting. Namely, the operation detecting means 31 detects two states, i.e. a state wherein the operation is still carried on even after the limit value of the setting is reached and a state wherein the operation is not carried on and sets the parameters to different values by a parameter setting device 32. Consequently, the parameter can be set in a short period of time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Second Industrial Fields of Application] The present invention relates to a parameter setting device that can set electronic musical instrument parameters so that they are easy to use near the limit values of the device.

[Prior Art] This device is capable of setting a large number of parameters for an electronic musical instrument, and when a performer sequentially operates the operators to set a desired value, the performer usually operates according to a predetermined arrangement order. The positive or negative direction is changed depending on the child. For example, if there are two types of controls, one for changing +1 and one for changing -1, and the device is capable of setting up to 100 types, if the upper limit of number 100 is reached by operating +1, the upper limit of number 100 is reached by operating +1. Even if you keep pressing the button, you cannot change the setting at the upper limit of number 100. For example, if you want to change it to number 50, you have to operate the -1 control. Further, when the lower limit number 00 was set by operating the -1 operator, the state of number 00 could not be changed even if the -1 operator was continued to be operated.

In another device, the selection was changed in the positive direction ↓ in accordance with a predetermined arrangement order, and after reaching the upper limit, the selection was repeatedly changed in the same order starting from the lower limit.

For example, after number 100, it returned to number 00, then +1, and so on. Similarly, if the operation of the same operator continues even after the value changes in one direction and reaches the lower limit number O0, the value is immediately changed to the upper limit value and then decreases.

[Problems to be Solved by the Invention] In the conventional device described above, operation is extremely troublesome at the upper and lower limit values of the device. That is, in the former device in which the setting is fixed at a limit value, it takes a long time to set because the setting cannot be moved to the next state beyond the limit value. For example, if you are currently setting number 75 and want to change it to number 10, it will be faster to change it beyond the upper limit of number 100 than to change it below number 75 using the -1 control. I can't change that setting.

In addition, although the latter device can process setting changes quickly, the change direction is always one step at a time. Therefore, it took a long time to change the set value beyond the limit value because it went too far.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a parameter setting device for an electronic musical instrument that can improve the above-mentioned drawbacks and improve the setting efficiency by changing the parameter setting state by operating the operator near the limit value. .

[Means for Solving the Problems] FIG. 1 is a diagram showing the basic configuration of the present invention. In FIG. 1, 2 is an operator, 30 is a means for detecting that a limit value has been exceeded, 31 is an operation detecting means, and 32 is a parameter setting device.

The present invention has the following configuration in a parameter setting device for an electronic musical instrument that is set to a predetermined state when the operator 2 is continuously operated and reaches a predetermined value. That is, a means 30 for detecting that the operator has been continued to be operated up to the set limit value of the parameter, an operation detecting means 31 for detecting whether the operation continues even after reaching the limit value, and the operation detecting means 31. The parameter setting device 32
Configure by setting the setting values of each to different values.

[Operation] According to the present invention, when the user continues to operate the operator to change the parameter settings, the limit operation detection means 30 detects that the operation has reached the limit value.

The operation detection means 31 detects that the operator 2 has been operated, and normally changes the settings of the parameter setting device 32 one after another. When the limit operation detection means 30 detects that the set limit value has been reached, the detection means 30 sends an output signal to the operation detection means 31 to detect the operation state of the operator 2. That is, the operation detecting means 31 detects two states: when the set limit value has been reached and the operation continues, and when the operation does not continue. Then, the parameter setting device 32 is caused to set the parameters to different values.

[Embodiment] FIG. 2 shows an overall block diagram of an electronic musical instrument including an operation panel 1, as an embodiment of the present invention, in a case where settings such as tone color are changed using an operator. In Figure 2, 1 is an operation panel, 2 and 3 are operators for changing settings, and 2 is +1
3 indicates a change by -l. 4-1 to 4-3 are switches for selecting and specifying the contents to be set. For example, A! 4-1↓Ma tone, 4-2 is volume,
4-3 is defined like an enrobe waveform. Reference numeral 5 indicates a window of a display device that displays setting value changes. Also, 9 is the keyboard,
10 is a central processing unit, 13 is a musical tone forming circuit, 15 is a program & data ROM, 16 is a datum work RAM,
19 is a D/A converter, 20 is an amplifier, and 21 is a speaker. A program and data ROM 164 stores programs for controlling the operation of the central processing unit 10, waveform data for musical tones, data for displaying on the display device 5, and the like. In addition, the datum work RAM 17 contains panel work registers necessary for detecting events of the controllers 2.3, registers for setting parameters such as tone, work registers for displaying parameter values, and parameter types. It is provided with a buffer for storage, a status register indicating various request signals, a status register indicating the status of various operators, and a counter indicating parameter switching time.

In FIG. 2, after the Reigen is turned on, the central processing unit 1 controls the operation of the controls 2.3 on the panel and the keys pressed on the keyboard 9.
0 repeatedly scans, and when it detects that the scan has been performed, it starts panel processing or key processing. Now, when detecting that the operator 2.3 has been operated, the central processing unit 10 starts processing according to the operation flowchart of panel processing shown in FIG. In FIG. 3, in step ■ it is determined whether or not the panel surface controls are on/off, and if the answer is yes, it is determined in steps ■ and ■ whether it is the operation of the controls 2.3 or the selection switch 4. . If the former is affirmative, the process proceeds to the tone color number setting process 0 in step (2), and if the latter is positive, the process proceeds to the parameter selection process. And step■
In step 1, the parameter type is set and parameter value display processing is performed, and then the process returns to step.

FIG. 4 is an operational flowchart showing details of the tone color number setting process in FIG. 3. Step ■ shown in Figure 4,
In (2), it is detected whether the set value set by the operator B has reached the lower limit value OO or the upper limit value 100. This is done using the parameter setting lens of the data & work RAM 17 shown in FIG. Determine whether it is the setting number of the tone setting or the lower limit value, and if it is the lower limit value, in step ■,
At that time, is the -1 operator 3 being operated continuously?
Please judge. If this continues, the lower limit value OO is set as the timbre setting number in step @. If the operation of the -1 operator 3 is once released, the process advances to step [phase] and the tone color number rloIJ is set. Then, when the 11 operator 3 is operated successively, the value of "-1" is calculated with the rlo1j and "10
Obtain and set 0 1.

Therefore, if the operation of the -1 operator 3 continues, the setting number is changed to 99 and the process returns to step (2).

If the timbre setting number is not the lower limit value in step 7 (■), it is determined in step (2) whether the upper limit value is correct. If it is the upper limit value, it is determined in step (2) whether or not the +1 operator 2 has been operated continuously. If this continues, the upper limit is set to 100 in step C.
Set. If the operation of the 7+1 operator is once canceled, the process proceeds to step (2) and the tone number "-1" is set. Next, when the +1 operator 2 is operated successively, the "-"
Calculate the value of ``+1'' of the operator to ``1'' to obtain ``00'' and press the button. If the +1 operator 2 is operated further, the setting number is changed to "1" and the process returns to step (2).

When the timbre setting number is an intermediate value between the upper limit and the lower limit, the intermediate value is set at step o from 8.

The parameters set according to the present invention are not limited to the timbre setting number, but are the same even if they are other types of parameters.

Thus, according to the present invention, when the limit value is reached because the operation of the operator continues in the same direction, the detecting means detects whether the operation continues in the same direction. do. When it continues as it is and when the operation is canceled -5
The effect is that when setting parameters such as timbre, it is possible to set parameters such as timbre in a shorter time compared to conventional methods. has. When changing settings beyond the limit value, it will not go too far.
