The tone generator 8 reads out musical tone waveform data and envelope data corresponding to the signal sent from the read control unit 14 of the CPU 1 from a waveform memory (not shown), adds an envelope to the read musical tone waveform data and adds a musical tone. It is output as a signal.

The tone signal output from the tone generator 8 is supplied to the D / A converter 10. Therefore, the tone generator 8 is connected to a waveform memory (not shown) for storing waveform data and envelope data.

The tone generator 8 includes a digital control oscillator (DCO) 17, a digital control filter (DCF) 18, a digital control amplifier (DCA) 19, and an effect (EFFECT) 2.
It is composed of 0.

Digital control oscillator (DC
O) 17 is for generating a tone signal. This DC

FIG. 2 is a diagram for explaining an example of the relationship between the operation amount of the operator 6 and the change amounts of a plurality of parameters.

In the present invention, the operators 6 are provided in classification categories such as "rich", "soft", and "bright" that the performer can easily understand. Operate 6 to set the tone.

On the other hand, the control of the electronic musical instrument of the present invention is controlled by the DCO, DCF, DCA, and EFFEC as in the conventional electronic musical instrument.
It is controlled by the elements of T. Therefore, each operator 6 of the present invention
Elements such as "chorus" and "reverb" are connected to the.

Then, for example, when the "rich" operator is operated, the EFFECT chorus and reverb are operated, and when "metal" is used, the EFFECT chorus, equalizer, and volume are operated. The categories are stored in the parameter conversion table 15 of the ROM 2 in advance.

On the other hand, the above D corresponding to the operation amount of the operator 6
The effectiveness of CA, DCF, and EFFECT is determined by the control curve shown in "Example of curve for controlling various elements" illustrated in FIG.

Therefore, for example, the chorus shown in FIG.
(A), FIG. 2 (C) for the equalizer, and FIG.
As in (B), a control curve to be applied in advance is determined according to the characteristics of each element.

In this state, for example, if the manipulator indicating "rich" is changed by the change amount 40, the change amount 90 is set for the parameter "chorus" in the characteristic curve shown in FIG. 2 (A). , The parameter "equalizer" is
The change amount 60 is set by the characteristic curve shown in FIG.

As described above, according to the present invention, it is possible to easily obtain a desired timbre change by operating the operating element 6 which the performer can easily understand.

Next, the operation of the electronic musical instrument of the present invention will be described with reference to FIG.
This will be described with reference to the flowchart of FIG.

When the power is turned on, first the CPU 1 and the RAM
3, an LSI (not shown) or the like is initialized, and initial values such as set values of the manipulator 6 are set in a predetermined area of the RAM 3 (new buffer B).
(Step S11).

Then, the set value of the operator 6 is read (step S12). This is the setting value of each operator 6 detected in the panel event processing such as the initial setting value and stored in the predetermined area (new buffer B) of the RAM 3 in the RAM.
This is the process of reading from 3.

Next, the set value of each operator 6 read in step S12 is stored in the old buffer A for the operator of the RAM 3 (step S13).

Then, it is checked whether or not the operator 6 has been operated (step S14). This is a process of comparing the value of the manipulator 6 read by the panel scan this time with the value stored in the old buffer A to check whether there is a manipulator 6 newly operated.

If there is no operator 6 newly operated in step S14, it is not necessary to change the timbre, and the process returns to step S13 and the same processing is repeated.

On the other hand, if there is a manipulator 6 newly manipulated in step S14, the value of the manipulator 6 is stored in the new buffer B (step S15).

Next, the data of the operated parameter is read (step S16). That is, referring to the parameter conversion table 15 stored in the ROM 2, the parameter data corresponding to the operated operator 6 is read.

Therefore, the parameter conversion table 15 stores data for designating the element to be manipulated and the degree of effectiveness corresponding to the designated manipulator 6, for example,
Elements that should be operated such as "chorus" and "reverb" when the "rich" controls are operated, and "volume" and "reverb" when the "dynamic" controls are operated. It is specified.

Then, the amount of change of each element designated in step S17 is obtained (step S17). This is based on a curve for controlling various elements illustrated in FIG. 2 according to the operation amount of the operator 6 of the present invention. For example, "reverb" is a curve (B) and the change amount is 20, or "volume". Is a curve (D) and the change amount is 20.

Then, step S16 and step S1
The parameter value of each operator 6 is updated based on the change factor and the change amount obtained in step 7 (step S18), and the process returns to the main routine.

In this way, the parameters designated by the operator 6 which the player can easily understand are converted into the parameters designated by the conventional elements such as chorus and reverb.

The electronic musical instrument of the present invention can be realized mainly by a program and a memory (table and data), and can be realized at a low cost without requiring a great change in the structure of the conventional electronic musical instrument.
