(B) Volume, tempo amount, transpose amount, etc. When the volume is changed, the tempo amount, transpose amount, etc. are changed in relation to each other. Therefore, the tempo amount, the transpose amount, and the like are associated with the operator for changing the volume. The conversion characteristic between the tempo amount and the transpose amount is set such that it slightly decreases when the volume increases.

(C) Envelope effect amount, volume, tempo amount, transpose amount, etc. When the envelope effect amount is changed, the volume, tempo amount, transpose amount, etc. are changed in relation to each other. Therefore, the volume, tempo amount, transpose amount, and the like are associated with the operator for changing the envelope-like effect amount.

The conversion characteristic of the harmonic component amount (filter control amount) is a characteristic that slightly decreases when the pitch effect amount increases, and the volume conversion characteristic slightly increases when the pitch effect amount increases. This is an increasing characteristic. The conversion characteristics of the tempo amount and the transpose amount are characteristics that slightly decrease when the pitch effect amount increases.

(E) The amount of reverberant effect, the amount of pitch effect, the amount of envelope effect, etc. When the amount of reverberant effect is changed, the amount of pitch effect, the amount of envelope effect, etc. are changed in relation to each other.

The tempo amount conversion characteristic is a characteristic that increases when the quantize amount increases. The volume conversion characteristic is a characteristic that increases slightly when the quantization amount increases. The conversion characteristics of various effect amounts are characteristics that decrease when the quantize amount increases.

Accordingly, an operator for changing the touch amount or an operator for changing the touch sensitivity amount includes the harmonic component amount (filter control amount), the pitch effect amount, the reverberation effect amount, and the frequency modulation amount. , Volume, transpose amount, tempo amount, and the like. The conversion characteristics of the harmonic component amount (filter control amount), pitch effect amount, reverberation effect amount, frequency modulation amount, volume, transpose amount, and tempo amount show that the touch amount or the touch sensitivity amount increases. , These musical parameters also increase.

The musical parameters that are mainly changed are determined for each operator.

The amount is mainly changed, and the operation element (h) mainly changes the touch amount or the touch sensitivity amount.

The conversion characteristics of these main musical parameters are characteristics that increase or decrease in accordance with the increase or decrease of the operation amount X of the operating element, and are the characteristics shown in (characteristic 1) to (characteristic 40) in FIG. . For example, if it is the direct proportional characteristic shown in (Characteristic 1),
The main musical parameter changes in direct proportion to the increase or decrease of the operation amount X of the operator.

Similarly, the conversion characteristic of the musical parameter that changes in relation to the main musical parameter stored in the conversion data table is a conversion characteristic for the operation amount X of the operation element. Therefore, a characteristic in which the correlation between the musical parameter that changes in relation to the main musical parameter is replaced with the correlation with the operation amount X is obtained in advance,
The obtained conversion characteristic data is stored in the conversion data table. However, when the conversion characteristic of the main musical parameter is the direct proportional characteristic shown in (Characteristic 1), the manipulated variable X and the change amount of the main musical parameter correspond one-to-one. No need.

Further, a plurality of musical parameters related to each other are changed by operating one operation element. Therefore, when a plurality of operators are operated, a certain musical parameter may be changed a plurality of times by the operations of the plurality of operators.

The conversion characteristics of all or some of the musical parameters (a) to (h) may be completely opposite.

For the foot switch 37, predetermined operation amount data X is generated for each operation, or the operation amount data X increases by a fixed amount according to the number of operations. If the foot switch 37 is a toggle switch that can be turned on / off, the operation amount data X is increased according to the number of on operations, and the operation amount data X is decreased according to the number of off operations. Further, the factor switch group 38 is the difference between the number of times the switch has been operated in the + direction and the number of times the switch has been operated in the − direction since “0” is displayed on the LED 32.

In this parameter setting process (step 102), a change amount of a musical parameter that changes in relation to the operation element is calculated according to the operation amount of the operation element that has been operated. Then, the obtained change amounts are synthesized for each of the musical parameters PARA1 to PARA200.

In the tone generation process (step 104), a key-on / key-off event is determined based on the scan data input from the keyboard scan circuit 2 to the CPU 5, and the tone data together with the key number data is sent to the tone generator. At this time, the musical parameter data set by the parameter setting process (step 102) is used as a part of the musical tone data. In the MIDI process (step 106), a MIDI output process for outputting musical tone information according to the operation of the keyboard 1, the panel switch group 3, the knee lever 36, the foot switch 37 and the like via the MIDI interface 9, and an input via the MIDI interface 9 And a median process for processing the generated musical sound data.

On the other hand, if the ON / OFF data for the operation element S1 is "1", the operation of the operation element S1 has been performed, and then the ON / OFF data is reset to "0" ( Step 121). Then, new operation amount data X1new of the operation element S1 stored in the operation amount / change amount data register is read (step 122).
Next, the operator S1 is read from the conversion data table in the ROM 7.
Is read, and an operation is performed to obtain the variation amounts Y10 to Y13 of the musical parameters related to the operation element S1 (step 124). The calculation of the change amount Y of the musical parameter is performed according to the following calculation expression (1).

Y = fa (X) × (dep / 100) (1) where fa (X) is one of the characteristic data stored in the conversion characteristic data table, and a is the characteristic. Indicates the data number. For example, f5 (X) indicates that the amount of change is obtained according to the characteristic 5.

As shown in FIG. 6, the musical parameters that change in relation to the operation element S1 are PARA3, PARA1
0, PARA15, and PARA101. PARA3
Changes according to the characteristic 1, and the degree of change is 100%.
Therefore, PARA3 for the operation amount X1new of the operation element S1
Is Y10 = f1 (X1new) .times. (100/100).

The PARA 10 changes according to the characteristic 2, and the degree of change is 30%. Therefore, the change amount Y11 of the PARA 10 with respect to the operation amount X1new is Y11 = f2 (X1new) × (30/100). The PARA 15 changes according to the characteristic 4, and the degree of change is 5%. Therefore, the change amount Y12 of the PARA 15 with respect to the operation amount X1new is Y12 = f4 (X1new) × (5/100). Further, the PARA 101 changes according to the characteristic 7, and the degree of change is 50%. Therefore, the change amount Y13 of the PARA 101 with respect to the operation amount X1new is Y13 = f7 (X1new) × (50/100). The change amount data Y10 thus obtained,
Y11, Y12, and Y13 are written to the change amount data register of the RAM 6.

Similarly, when the operation of the operators S2 to Sm is performed, the operation amount data X 2new to X
mnew is read from the RAM 6 and the change amount data Y of the musical parameter changed by the operation of the operation element is obtained (steps 126, 128, 130,...). Then, a change amount synthesis process (step 200) is performed.

10. FIG. 9 shows a flowchart of the change amount combining process (step 200) in FIG. In this process, the change amount data Y obtained by the parameter setting process 102 is summed for each type of musical parameter, and is combined with the musical parameter data before the operation of the operation element is performed. As described above, a plurality of mutually related musical parameters are changed by the operation of one operator. Therefore, when a plurality of operators are operated, a certain musical parameter may be changed a plurality of times by the operations of the plurality of operators. Therefore, in this process, the amounts of change of the musical parameters changed a plurality of times are summed up.

First, the value of the count data n provided in the RAM 6 is reset to the parameter number Pn (step 202). In this embodiment, the number of parameters Pn is 200. Next, the musical parameter data PARA2 stored in the musical parameter data register of the RAM 6
00 is read, and the read musical parameter data PARA200 is combined with the total value of the variation data of the PARA200 in the variation data Y of the musical parameters (step 204). Note that this combination may be an operation combination based on a predetermined operation expression instead of addition (accumulation).

In this step 204, the conversion data table is searched, whereby the PARA 200
Are picked up. Are sequentially read out from the change amount data register of the RAM 6 and summed. Then, the total value is used as the change amount combining process (step 20).
0) is started before the musical parameter data PARA
The value of the new musical parameter data PARA200 is calculated by being combined with the value of 200. This new musical parameter data PARA200 is temporarily stored in a buffer register in RAM6. This buffer register stores each musical parameter data PARA1 to PARA2.
00 is provided.

Then, the count data n is counted down by "1" (step 206), and the count data n becomes "0" for the total number of parameters Pn (step 208). Is repeatedly executed. Thereby, for all musical parameter data PARA200 to PARA1,
The change amount data is totaled, and the total value is combined with the musical parameter data before the operation, and new musical parameter data PARA200 to PARA1 are calculated.

Next, new musical parameter data PA
RA1 to PARA200 are modified so as to be within a predetermined range (steps 210 to 224). First, the count data n is reset to the parameter number Pn (step 210). Next, the musical parameter data P
It is determined whether ARA 200 is smaller than lower limit data MIN 200 (step 212). The musical parameter data PARA200 is lower limit data MIN200
If it is smaller, the musical parameter data PAR
The value of A200 is changed to the value of lower limit data MIN200 (step 214). If the musical parameter data PARA200 is equal to or larger than the lower limit data MIN200, the musical parameter data PARA200 remains as it is. When the musical parameter data PARA200 has been changed, the data stored in the buffer register is the changed musical parameter data PARA200.
Replaced with 200.

Next, the musical parameter data PARA2
It is determined whether the value of 00 is greater than the upper limit value data MAX200 (step 216). If the musical parameter data PARA200 is larger than the upper limit data MAX200, the musical parameter data PARA2
The value of 00 is changed to the value of the upper limit data MAX200 (step 218). Musical parameter data PARA
If 200 is less than or equal to the maximum value data MAX200, the musical parameter data PARA200 remains as it is.
When the musical parameter data PARA200 is changed, the data stored in the buffer register is replaced with the changed musical parameter data PARA200.

Next, the musical parameter data PARA200 stored in the buffer register is stored in the RAM.
6 is updated and stored in the musical parameter data register (step 220). Then, the count data n is counted down by “1”, and the processes of steps 212 to 224 are repeatedly executed until the count data n becomes “0”. As a result, all the musical parameter data PARA200 to PARA1 are corrected so as to have a value between the lower limit value MINn and the upper limit value MAXn, and the new musical parameter data PARA200 to PARA1 after the correction are stored in the RAM 6. It is updated and stored in the musical parameter data register.

Each musical parameter data PARAn
The lower limit value MINn and the upper limit value MAXn for each are stored in the ROM 7 as a data table.
Alternatively, in step 216, data corresponding to the musical parameter data PARAn is read. The lower limit value MINn and the upper limit value MAXn may be variable.

As described above, in the present embodiment, the change amount Y of the musical parameter that changes in relation to each of the operators is obtained according to the operation amounts X1 to Xm of the plurality of operators, and the same musical parameter is changed. The amounts of change Y are summed, and this sum is combined with the value of the musical parameter before the operation of the operator. Therefore, the values of a plurality of mutually related musical parameters can be changed by operating one operation element.

Further, since the plurality of musical parameters changing in relation to each other change with predetermined conversion characteristics determined so as to be mutually optimal, when the main musical parameter changes, The value of the musical parameter that changes in relation is automatically set so as to be the optimum condition. For this reason, it is not necessary to manually adjust a plurality of operators so that the optimum condition is obtained by operating the controls a number of times, and it is possible to obtain a desired tone and effect in a short time.

Further, as described above, the function of changing the musical parameters related to each other in response to the operation of one operating element may be stopped. In this case, a switch for switching operation / stop of the function is provided. Then, when the function is stopped, the musical parameters changed by the operation of each operation element are only the main musical parameters. In addition, the operation / stop of the function may be switched for each part or each of the operators.

Further, in the variation synthesizing process (step 200) shown in FIG. 9, steps 206 to 210 are omitted, and if the determination in step 224 is NO, step 2 is executed.

Alternatively, the amount may be changed from the operation value.
