ABSTRACT:
A musical tone forming system includes a waveform storage device for storing data representative of an attack portion of a musical tone waveform and data representative of part of the other portion of the musical tone waveform following the attack portion. An address device addresses the waveform storage device to first read the data representative of the attack portion and to then repeatedly read the part of the waveform from the waveform storage device to thereby form a musical tone signal. There is provided a device for generating data varying with time. The address device feeds an address data to the waveform storage device in accordance with the time-varying data to randomly designate as a starting address one of those addresses of the waveform storage device storing the data of the part of the waveform, thereby realizing a noisy nature characteristic of a percussion instrument.
