Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of use> The present invention relates to a parameter setting device for an electronic musical instrument, and more particularly to a parameter value designating switch for setting a parameter value stepwise using a switch or the like. The present invention relates to a parameter setting device that can be set in multiple stages without significantly increasing the value.

<Prior Art> In general, various parameters are used for electronic musical instruments for controlling musical sounds and various functions, and an example of a parameter setting device for setting the values of such parameters is a practical example.
No. 10496. The parameter setting device described in this publication corresponds to a plurality of settable parameter values, and a plurality of parameter values (in the embodiment shown in FIG.
Individual) pushbutton switches PBO to PB7 are provided, and the player presses any one of the pushbutton switches PBO to PB7 to set the parameter to the value assigned to the pushed pushbutton switch. It has become so.

<Problems to be Solved by the Invention> Since the conventional parameter setting device described above is provided with the switches corresponding to the respective values of the settable parameters, the settable parameter value is increased and the parameter value is changed. To be finely configurable, the number of switches had to be increased significantly. Such an increase in the number of switches impairs the operability of the parameter value specifying operation by the performer, and also increases the manufacturing cost of the electronic musical instrument due to the complexity and size of the operation panel on which the switches are arranged. There were also points.

Therefore, it is an object of the present invention to provide a parameter setting device for an electronic musical instrument, which can maintain good operability even if parameter values can be set finely, and does not require a complicated and large operation panel. There is.

<Means for Solving Problems> An electronic musical instrument parameter setting device according to the present invention sets a plurality of types of parameter values for musical tone control for controlling musical tones or function control for controlling various functions of the electronic musical instrument. In the parameter setting device for an electronic musical instrument, a plurality of parameter value designating operators, which are provided for each type of the parameter and are capable of designating the value of the parameter in a plurality of steps at a first predetermined value interval, and the parameters of the plurality of types. A parameter value change designating operator that is provided in common for each of the values that can be designated by the parameter value designating operator at a second predetermined value interval smaller than the first predetermined value. Storage means for storing parameter type data representing the type of parameter designated by the parameter value designating operator, and parameter type data stored in this storage means Storage control means for updating parameter type data representing the type of parameter corresponding to the specified parameter value specifying operator every time the value of the parameter is specified by any of the plurality of parameter value specifying operators. , The parameter value of the type corresponding to the operated parameter value designating operator is set, and the value of the parameter of the type represented by the parameter type data stored in the storage means is designated by the parameter value change designating operator. The gist of the present invention is to have a parameter value setting means for setting based on the above.

<Operation and Effect> In the parameter setting device of the electronic musical instrument according to the above configuration, when setting the parameter, first, the parameter value is specified by the parameter value specification operator. Since the parameter value designating operator designates the parameter value at the first predetermined value interval, the parameter value designating operator designates the approximate number of the parameter value in units of the first predetermined value.

Next, when it is desired to stabilize the value between the parameter value specified by the parameter value specification operator and the parameter value above or below the parameter value, the parameter value change specification operator specifies the parameter change value. . Since the parameter value change designating operator can designate the parameter change value in units of the second predetermined value smaller than the first predetermined value, the parameter value change designating operator already sets the parameter based on the change value specified by the parameter value change designating operator. When the parameter value specified by the value specification operator is changed, the changed parameter value is set to a value between the approximate numbers that can be specified by the parameter value specification operator.

Here, if the number of parameter values that can be specified by the parameter value specifying operator is m, the parameter value specifying operator is m
When the number of change values that can be specified by the parameter value change designating operator is n, the parameter value change designating operator also has a size corresponding to n. Therefore, if an attempt is made to set a parameter value having the same fineness as that of the present invention in the conventional parameter setting device, the size of the conventional parameter setting device becomes {(m-1) .n + m} = m (N + 1) -n. It becomes the corresponding size. On the other hand, the parameter setting device according to the present invention has a size corresponding to m + n only. That is, the conventional parameter setting device has a size corresponding to the product of m and n, whereas the parameter setting device according to the present invention has a size corresponding to the sum of n and n. It is possible to reduce the size of the parameter setting device.

As a result, when setting the parameters, the player has only to operate the miniaturized parameter setting device, and the operability at the time of parameter setting can be improved. Also,
Since the parameter setting device can be downsized, the operation panel can also be downsized, and the manufacturing cost of the electronic musical instrument can be reduced.

Further, in the parameter setting device according to the present invention, a common parameter value change designation operator is provided for a plurality of parameter value designation operators. Then, the type of the parameter designated by the parameter value designating operator is updated and stored. Therefore, it is possible to always set the value of the parameter of the type corresponding to the designation of the parameter value designation operator.

Other controls for multi-menu by performer 16
When the increase switch 151 is pressed without operating 0, an increase switch ON event is detected in step P5 of the main routine, and the subroutine shown in FIG. 2 (C) is executed. In this subroutine, first, it is determined whether or not the volume flag VLFLG is "1" (step P22). In this case, since the volume flag VLFLG has been set to "1" in step P16, the determination result in step P22 is YES, and the volume data VLDATA (SK) to VLDATA relating to each sound group in the register 302 is set.
The volume data VLDATA (SK) corresponding to the sound group represented by the sound group data VLTC in the register 303 of (LK) is read, and “1” is added to the “4” value of this volume data VLDATA (SK) to adjust the volume. After changing to the volume data VLDATA (SK) indicating the value "5", it is stored again in the register 302 (step P23). Since the maximum volume value is "24", the volume data VL
When DATA is "24", volume data
VLDATA is not increased.

A process of increasing the value of the parameter corresponding to 160 is executed (step
P27).

On the other hand, when decreasing the value of the volume data VLDATA (SK), the decrease button 152 is pressed without operating the other operation group 160 related to the multi-menu. When the ON event of the decrease button 152 is detected, the subroutine for the decrease button ON event shown in FIG. 2C is executed. Even in this decrease switch ON event subroutine, the volume flag VLFL
First, it is determined whether G is "1" (step P28). When the decrease button 152 is pressed without operating the other operation group 160 related to the multi-menu, the determination result in step P28 is YES, so the process proceeds to step P29. In this step P29, the volume data VLDATA (SK) is read from the register 302 based on the sound group data VLTC of the register 303 in the same manner as the above-mentioned step P28, and the value “4” to “1” of the volume data VLDATA (SK) is read. Is subtracted to change the value of the volume data VLDATA (SK) to “3” and then stored in the register 302. In addition, volume data VLD
Since the minimum value of ATA is "0", when the volume data VLDATA is already "0", the volume data VLDATA is not subtracted. Thereafter, steps P24 to P26 are executed as in the case where the increase button 151 is pressed, and the process returns to the main program. At this time, the light emitting diodes of the volume designating switch group 110 light up ID2 according to the relationship in the attached table, and the display 153
In addition to "VOLUME CONTROL", "VALUE = 3"
Is displayed. When the volume value is further reduced, the reduction switch 152 may be pressed again.
