ABSTRACT:
A tone generation control unit has four waveform read/write channels for selectively the reading or writing data in a waveform memory. A plurality of waveform signals stored in the waveform memory are converted into analog signals to be subjected to timbre and tone volume control through voltage-controlled filters and voltage-controlled amplifiers before being fed to a mixing adder. An output signal of the mixing adder is converted into a digital signal which is stored in the waveform memory again through processing of the tone generation control unit. The stored converted output from the mixing adder is later used again as a new sound source waveform which is operated on to produce tones.
