Abstract
In an electronic musical instrument of the type in which pitch selection is achieved by pulse position modulation, and a rhythm accompaniment is played automatically under the direction of a read-only memory, a shift register is used to create pulse position modulation instructions for harmonic footages of the fundamental note, and selected combinations of these footages are rhythm-modulated and rhythm-counter-modulated under the control of logic gates which are responsive to various manually operated stop tabs.
