Abstract

PURPOSE:To obtain excellent operability by enabling desired tone control by one-touch operation by previously storing tone control information in a memory, and controlling a tone control circuit by the readout output of the memory. CONSTITUTION:Level up-down keys 12 and 13, and keys 14 and 17 for frequency switching are operated and under the command of a microprocessor 19, tone control circuits 8 and 9 are controlled to obtain desired sound quality characteristics. Then while a preset button 25 is pressed, a memory button 24 is pressed to store tone control information in a memory 20 through a microprocessor 19. With keys 12-17, the tone control information stored in the memory 20 is read out under the command of the microprocessor 19 and then supplied to tone control circuits 8 and 9 through a shift register 22 and a decoder 23 to obtain an output signal which has sound quality characteristics at the side of an output terminal 11.
