ABSTRACT:
An electronic musical instrument produces musical tones based on waveform data, while providing smooth changes between different timbres and at the same time avoiding reduction in the efficiency of waveform compression. The timbre change is carried out in an interpolation interval, the magnitude of which varies in accordance with the magnitude of the timbre change. The data necessary to establish the interpolation interval may be stored and read out of a memory or may be determined by interpolation according to a linear function.
