ABSTRACT:
In a musical instrument in which a plurality of data words corresponding to the amplitudes of a corresponding number of evenly spaced points defining a cycle of an audible musical waveform are transformed at an average rate corresponding to the fundamental frequency of the tone being generated, a computation means is provided to produce musical tones having an ensemble effect. The computation means comprises a multiplicity of interpolation calculations whereby a sequence of interpolated waveshape points are obtained from two different waveshapes whose data points are addressed from waveshape memories at different memory advance rates.
