DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter setting device for an electronic musical instrument, and more particularly to a device 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 any change.

[0002]

2. Description of the Related Art In general, various parameters for tone control and various function controls are used in electronic musical instruments, and an example of a parameter setting device for setting the values of such parameters is disclosed in Japanese Utility Model Laid-Open No. 58-10496. It is described in.
The parameter setting device described in this publication is provided with a plurality of (eight in the embodiment of FIG. 3) push button switches PB0 to PB7 corresponding to a plurality of settable parameter values, respectively. PB0 to PB7
Is pressed by the player, the parameter is set to the value assigned to the pressed push button switch.

[0003]

In the above-described conventional parameter setting apparatus, switches are provided corresponding to respective settable parameter values. Therefore, the settable parameter values are increased and the parameter values are finely adjusted. To be configurable, the number of switches had to be greatly increased. The increase in the number of switches impairs the operability of the parameter value designation operation by the player,
There is also a problem that the manufacturing cost of the electronic musical instrument increases because the operation panel on which the switches are disposed is complicated and large.

Accordingly, the present invention provides a parameter setting device for an electronic musical instrument which can maintain good operability even if parameter values can be set finely and which does not require a complicated and large operation panel. It is an object.

[0005]

A parameter setting device for an electronic musical instrument according to the present invention sets values of a plurality of types of parameters for musical tone control for controlling musical tones or for function control for controlling various functions of the electronic musical instrument. In the parameter setting device for an electronic musical instrument, a plurality of first operators provided for each type of the parameter and capable of specifying the value of the parameter in a plurality of steps at a first predetermined value interval; A second manipulator which is provided in common with each other and specifies between the values that can be specified by the first manipulator at a second predetermined value interval smaller than the first predetermined value; Storage means for storing parameter type data indicating the type of parameter designated by one operator, and parameter type data stored in the storage means being transmitted by one of the plurality of first operators; Each time a meter value is specified, a storage control unit that updates the parameter type data indicating the type of the parameter corresponding to the specified first operation element, and a type of the type corresponding to the operated first operation element Parameter value setting means for setting the value of the parameter and setting the value of the parameter of the type represented by the parameter type data stored in the storage means based on the designation of the second operation element; The point is that the range of parameter values that can be set by the operator is the same as the range of parameter values that can be set by the second operator.

[Operation and Effect] In the parameter setting device for an electronic musical instrument according to the above-described configuration, a parameter value is first designated by a first operation element when setting a parameter. Since the first operation element specifies the parameter value at the first predetermined value interval, the first operation element specifies the approximate number of the parameter value in units of the first predetermined value.

Next, when it is desired to specify a value between the parameter value designated by the first operator and the parameter value above or below the parameter value, the second operator designates the parameter change value. specify. Since the second operator can specify a parameter change value in units of a second predetermined value smaller than the first predetermined value, the first operator has already specified the first controller based on the change value specified by the second operator. When the parameter value specified by the operator is changed, the parameter value after the change is set to a value between approximate numbers that can be specified by the first operator.

Here, if the number of parameter values that can be specified by the first operator is m, the first operator has a size corresponding to this m, and the change value that can be specified by the second operator is If the number is n, the second operator also has a size corresponding to this n. Therefore, when trying to set a parameter value of the same fineness as the present invention in a conventional parameter setting device,
The size of the conventional parameter setting device is a size corresponding to {(m−1) · n + m} = m (n + 1) −n. On the other hand, the parameter setting device according to the present invention has only a size corresponding to m + n. That is, while the parameter setting device of the related art has a size corresponding to the product of m and n, the parameter setting device according to the present invention only has a size corresponding to the sum of m and n. The size of the parameter setting device can be reduced.

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

In the parameter setting device according to the present invention, a common second operator is provided for a plurality of first operators. Then, the type of the parameter specified by the first 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 first operation element.

Further, since the range of parameter values that can be set by the first operator and the range of parameter values that can be set by the second operator are the same, the second fine adjustment operator is used. Can be set in the same range as the first operator, which is a coarse adjustment operator,
Operability of parameter setting is improved.

And supply these to registers 301 and 302
, And clear the other registers 303 to 307 (step P2).

Subsequently, a tone color selection switch group 10 for each tone group
Each of the switches 1, 102, 103, and 104 is sequentially scanned, and when it is detected that any one of the tone selection switches is turned on in each of the switch groups 101, 102, 103, and 104, the tone corresponding to the tone selection switch is detected. The data TCDATA is written into the address corresponding to the tone group of the operated tone color selection switch in the register 301, and the tone color data TCDATA of each tone group (SK, US, UD, LK) stored in the register 301.
(SK) to TCDATA (LK) are converted to a tone generation circuit 40.

When the scanning and processing (step P5) relating to the multi-menu section 150 are completed, the scanning of the preset switch section 180 is performed, and the preset switch PR
When it is detected that the switches 1 to PR8 and the write switch M have been operated, a process relating to a preset switch group described in detail later with reference to FIG. 6 is performed (step P6).

When the scanning and processing (step P6) relating to the preset switch group are completed, scanning of the other operator group 160 relating to the multi-menu is performed, and when it is detected that any of the operators is operated, the operated operation is performed. Scanning the multi-menu section 150 by determining the child 160,
The process (step P5) is prepared (step P7).

When the scanning and processing of the other controls related to the multi-menu are completed (step P7), the other controls 170 are scanned, and when any of the other controls are operated, the operation is performed. A predetermined process for the child is performed (step P8).

When the scanning and processing for the other control elements are completed, the respective key switches of the solo keyboard 200, the upper keyboard 201 and the lower keyboard 202 are scanned, and any one of the keyboards 20 is scanned.
If the key is pressed at 0, 201, or 202, processing such as transmitting key data relating to the pressed key to the tone generation circuit 400 is performed (step P9).

Scanning and processing of each key (step P9)
Is completed, the process returns to the scanning and processing of each tone color selection switch (Step P3), and thereafter, each processing of Steps P3 to P9 is repeated.

Next, each volume designation switch group 110, 12
0, 130, 140 push button switches PB1 to PB
The processing when 7 is pressed will be described. The push button switches PB1 to PB7 of each of the volume designation switch groups 110, 120, 130, and 140 (in the following description, an example is described in which the push button switch PB2 of the volume designation switch group 110 is pressed) is pressed. And the above step P
4 and branches to a subroutine program shown in the flowchart of FIG.

That is, in the volume designating switch group ON event, first, the pressed push button switch PB
Sound group data VLTC representing an SK keyboard sound group (SK) corresponding to the volume designation switch group 110 to which P1 to PB7 belongs.
Is written into the register 303 (step P12), and the volume data VLD corresponding to the volume value “4” specified by the pressed push button switch PB2
The ATA is written into the register 302 at the address corresponding to the sound group (SK) represented by the sound group data VLTC (step P13).

Thereafter, the volume data VLDATA (SK) written in the register 302 is sent to the tone generator 400 (step P14).
The light emitting diode ID2 corresponding to the pressed push button switch PB2 is turned on (step P15). After the light emitting diode ID2 is turned on, the volume flag VLFLG in the register 304 is set to "1" (step P).
16) Then, the display 153 shows “VOLUM
With the display of “E CONTROL”, the value of the volume data VLDATA (SK) is changed to “VALUE =
4 is displayed (step P17).

Next, the case where the volume data VLDATA (SK) set by the above subroutine program is finely adjusted will be described. First, a description will be given of an example in which the value of the volume data VLDATA (SK) is increased by two steps and changed to the volume value (6).

The increase switch 151 is provided without the player operating the other operator group 160 related to the multi-menu.
Is pressed, an increase switch-on event is detected in step P5 of the main routine, and the subroutine shown in FIG. 5 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 decision result in the step P22 is YES, and the register 3
02 Volume data VLDATA for each sound group in 02
(SK) to VLDATA (LK)
The volume data VLDATA (SK) corresponding to the sound group represented by the sound group data VLTC No. 3 is read, and the value “4” of the volume data VLDATA (SK) is set to “1”.
Is added to the volume data VLDATA (SK) indicating the volume value “5”, and then the register 302 is re-registered.
(Step P23). Since the maximum value of the volume value is “24”, when the volume data VLDATA is already “24”, the volume data VLDATA is not increased.

After the volume data VLDATA (SK) is changed, the changed volume data VLDATA (SK)
(SK) is supplied to the tone generation circuit 400 (step P).
24) Then, according to the relationship shown in Table 1, the light emitting diode ID2 is turned on corresponding to the value “5” of the volume data VLDATA (SK) (step P2).
5). After that, the display 153 shows “VOLUM
With the display of “E CONTROL”, the value “5” of the changed volume data VLDATA (SK) is changed to “V
"ALUE = 5" is displayed (step P26).

As described above, when the increase button 151 is pressed once, the value of the volume data VLDATA is increased by "1", so that the volume data VLDATA (S
In order to change the value of K) to “6”, it is necessary to further press the increase button 151. When the increase button 151 is pressed again, the above-described steps P22 to P26 are performed.
Is repeated, and the volume data VLDATA (SK)
Is updated to “6” and the display on the display 153 is displayed together with “VOLUME CONTROL” and “VA
LUE = 6 ".

On the other hand, when the increase button 151 is pressed after the other operation group 160 relating to the multi-menu is operated, as shown in FIG.
Since the volume flag VLFLG of No. 4 is reset to "0" (step P31), the determination result of step P22 is NO, and a process of increasing the value of the parameter corresponding to the other operation element 160 related to the multi-menu is executed. (Step P27).

On the other hand, the volume data VL
When decreasing the value of DATA (SK), the user presses the decrease button 152 without operating the other operation group 160 relating to the multi-menu. When the ON event of the decrease button 152 is detected, a subroutine related to the decrease button ON event shown in FIG. 5 is executed. Even in this subroutine of the decrease switch ON event, it is first determined whether or not the volume flag VLFLG is “1”. It is determined (step P28).

If the decrease button 152 is pressed without operating any other group of operators 160 related to the multi-menu, the determination result in step P28 becomes YES,
Proceed to step P29. In step P29, the volume data VLDATA (SK) is read from the register 302 based on the sound group data VLTC in the register 303 from the register 302, and the value of the volume data VLDATA (SK) is changed from "4" to "1" in the same manner as in step P28 described above. Is subtracted to change the value of the volume data VLDATA (SK) to “3” and then stored in the register 302. In addition,
Since the lowest value of the volume data VLDATA is “0”, if the volume data VLDATA has already become “0”, the volume data VLDATA
No TA subtraction is performed.

Thereafter, steps P24 to P26 are executed in the same manner as when the increase button 151 is pressed, and the program returns to the main program. At this time, the LED of the light emitting diode of the volume designation switch group 110 is turned on in accordance with the relationship shown in Table 1, and the display 153 shows
Along with "VOLUME CONTROL", "VAL
UE = 3 "is displayed. To further reduce the volume value, the decrease switch 152 may be pressed again.

Next, a brief description will be given of a process when another operation element relating to the multi-menu is operated. When an ON event of another operator related to the multi-menu is detected, the subroutine of FIG. 6 is executed, the volume flag VLFLG of the register 304 is reset to “0” (step P31), and thereafter, other operations that have an ON event The processing of the parameters relating to the child is executed (step P32), but this point is not directly related to the gist of the present invention, and therefore detailed description is omitted.

Note that, when another operator related to the multi-menu is operated, pressing the increase switch 151 or the decrease switch 152 causes the parameter value related to the operator to be changed in steps P27 and P27 'in FIG. Is increased or decreased in the same manner as in the case of the volume data VLDATA, and the parameter value is displayed on the display 153.

Next, the processing when the preset switch section 180 is operated will be described. That is, when the ON events of the preset switches PR1 to PR8 are detected, the subroutine shown in FIG. 7 is executed, and first, the numbers of the pressed preset switches PR1 to PR8 are written in the register 306 (step P41). It is determined whether or not the write switch M is simultaneously pressed (step P42).

If the decision result in the step P42 is NO, a set of preset memory data PRMDATA (1) corresponding to the preset switches PR1 to PR8 pressed from the preset memory 307 based on the number data stored in the register 306. Or PRMDATA
(8), and reads out each data (TCDATA (SK) to TCDATA (L) in the preset memory data.
K), VLDATA (SK) to VLDATA (L
K) and the data relating to the other operators are transferred to the corresponding registers (301, 302, 305) (step P43).

Subsequently, the data TCDATA (SK)
VLDATA (LK) and data relating to other operators are transmitted to the tone generation circuit 400 (step P4).
4), pressed preset switches PR1 to PR8
The light emitting diodes ID11 to ID18 corresponding to are turned on (step P45). Thereafter, in accordance with the various data transferred to the registers 301, 302, and 305 in step P43, the switch groups 101 to 104, 110 to 140, and 1 for setting these data are set.
The display elements (light emitting diode I
D1 to ID8, etc.) are turned on (step P46).

On the other hand, if the decision result in the step P42 is YES, each of the registers 301, 302, 305
The tone color data TCDATA, volume data VLDATA, and data relating to other controls of each tone group written in the preset register 307 are collectively written to addresses corresponding to the pressed preset switches PR1 to PR8 in the preset register 307 (step P47). ).

As described above, in the above embodiment, the case where the present invention is applied to a parameter (volume data) setting device for controlling the volume of a musical tone has been described. Also, the present invention may be applied to setting of parameters relating to each time and level of ADSR in the envelope generator, or setting of parameters relating to speed and depth of a modulation effect such as vibrato. In the above embodiment, the parameter values are controlled by software, but may be controlled by dedicated hardware. Further, in the above embodiment, the fine adjustment of the parameter value is performed by the increase switch 15 of the multi-menu section 150.
Although the operation is performed using 1 and the decrease switch 152, an arbitrary operator such as a wheel operator or a numeric keypad may be used instead.

Further, in the above embodiment, the parameter values are set roughly by the switch groups 110 to 140, and the parameter values are sequentially raised or lowered each time the increase switch 151 or the decrease switch 152 is pressed. Alternatively, a plurality of values to be lowered may be written in the memory in advance, and a value corresponding to a stage to be raised or lowered may be read from this memory and calculated with a roughly set parameter value.

Further, the present invention is not limited to the setting of musical tone control parameters as in the above embodiment, but is applicable to the setting of rhythm tempo and other function control parameters in an automatic performance device or an automatic rhythm device. Is also good.
