ABSTRACT:
An addition section and a memory section for storing data to be inputted to the addition section are provided. A processing section variably performs a logical processing on output data of the memory section in accordance with a control signal and gives the data to the addition section. A control section controls introduction of data to the memory section and supply of the control signal to the processing section in correspondence to respective desired operations so that plural kinds of operations for tone signal generation may be respectively performed. With this arrangement, the addition section can be shared for various kinds of operations for the tone signal generation. Consequently, operation circuits for performing the various operations are integrated, so as to realize a substantial reduction of circuitry construction.
