Abstract
Polyphonic sound may be produced through the use of a tone generator which divides the high frequency output of a clock pulse generator by numbers which are allocated to individual keys or pedals of an instrument. The divisor values are stored in main and intermediate memories, the values in the intermediate memory subsequently being counted down to zero. An output signal, for control of a sweep voltage generator, is produced which is a function of all of the divisor values in the intermediate memory at any one time.
