There is provided a tone generator system that is capable of generating various types of high-quality musical tones by means of waveform storage means with a small capacity using a tone generator based on the waveform memory method. A first waveform storage stores compressed waveform data. A decoder operates in response to tone color changing instruction data included in musical composition data to be reproduced, to read out from the first waveform storage the compressed waveform data corresponding to at least one tone color corresponding to the tone color changing instruction data and decode the readout compressed waveform data into waveform data in a pulse code modulation format. A second waveform storage stores the waveform data in the pulse code modulation format decoded by the decoder.
