Abstract
A step signal of which the period varies according to random data is derived from a step pulse generator, and is supplied to an address counter. By the output data from the address counter, an address of a waveform ROM is specified. From a waveform ROM, the waveform based on the random data is output in the form of a distorted waveform signal. Using this output signal of the distorted waveform, a cymbal sound, for example, is generated in a musical tone generator.
