Abstract
An electronic organ includes digital circuitry for automatically enabling in a sequential manner a plurality of gates to pass tone control signals to keyers which generate corresponding tone output signals. The digital circuitry includes a tone counter which sequentially enables a plurality of tone gates, and an octave counter which sequentially enables output gates having inputs from the tone gates. A clock generates clock pulses which are rapidly counted by the note counter to sequentially scan the note gates. When a tone control signal is passed, the output of a note detector causes a divider to be inserted between the clock and the note counter to maintain enabling of the note counter.
