ABSTRACT OF THE DISCLOSURE An electronic musical instrument employs n-channel time-sharing to produce n notes simultaneously, without reducing frequency resolution to one n-th of the basic fre- quency of the time slots from which the channels are con- structed. Each note is constructed from a number of wave- form related sample values generated at intervals equal to an integral number of time slots. The samples are then applied to and delayed in a shift register by an interval equal to a number of time slots selected such that they arrive at the output of the shift register in a time slot allotted to the appropriate channel. The samples may be incremental and applied to appropriate stages of the shift register such that the output of the shift register in suc- cessive cycles of n time slots represents successive incre- ments of the waveforms of the notes assigned to successive channels, which increments may be accumulated.
