ABSTRACT:
An electronic musical instrument includes a plurality of address generators for producing address signals corresponding to different tones each varying at a rate synchronous with the frequency of each of the different tones, a waveform memory device including a plurality of addresses for storing at respective addresses a plurality of waveform sample values that constitute a waveform, a circuit for sequentially supplying one after another of the address signals to the waveform memory device to read out the waveform in different rates in a time division multiplexed manner for different tones, and musical tone forming circuits for forming musical tones in accordance with the time division multiplexed waveform outputs of the waveform memory device.
