Abstract

PURPOSE: To make it possible to suitably produce musical frequency signals having the desired height, tone and amplitude by using a computer system.
CONSTITUTION: There are provided in an electronic instrument: a CPU 1 and a memory 2 which are connected through a bus; a memory unit 3 for the waveform data signals in the memory; a latch circuit 4 for frequency data signals connected with the bus; a latch circuit 5 for waveform data signals; a latch circuit 6 for amplitude data signals; a circuit for generating high frequency signals several times the musical frequencies to be generated on the basis of the output of the circuit 4; and a counter 8 for counting the signals of the circuit 7 and for feeding the counted value as address signals through the bus to the memory 2. The waveform data signals of the memory 3 are repeatedly read out and fed to the circuit 5, and the amplitude signals from the CPU 1 are fed to the circuit 6. The outputs of the circuits 5 and 6 are subjected to signal processing so as to ganerate musical sound frequency signals.
