ABSTRACT:
A keyboard operated electronic musical instrument is disclosed in which musical tones are created by reading out preselected data values stored in a waveshape memory. A transformed sequence of these data points is generated such that a variable delay exists between the transformed sequence of data points read out of the memory. The selectively delayed sequences of points is combined with the original points to generate musical tones having an ensemble-like musical effect. Provision is made for varying the delay in a periodic cyclic fashion using a period the same as that for the stored data in the waveshape memory.
