Abstract
A tone signal generator utilizing ancillary memories for an electronic musical instrument system has a source memory storing a long and continuous waveform data and two ancillary memories each capacity of which is smaller than that of the source memory. A portion of the continuous waveform data from the source memory is written into one of the ancillary memories. After completion of the writing operation, the written waveform data is read out for tone production, and simultaneously another portion of the continuous waveform data is written into the other of said ancillary memories. The repetition of such operation make it possible to reproduce a long and continuous tone waveform in spite of the small capacity of the ancillary memories.
