ABSTRACT:
A digital sampling instrument for multi-channel interpolatative playback of digital audio data stored in a waveform memory provides improved interpolation of musical sounds by use of a cache memory. The present invention includes a plurality of interpolator circuits utilizing a single waveform memory where each of the interpolator circuits produces a unique bus request signal which is responsive to a unique bus acknowledge signal to determine which of the interpolator circuits has control of the waveform memory at any given waveform memory cycle.
