Abstract
An electronic organ includes digital circuitry for automatically enabling in a sequential manner a plurality of gates to pass tone signals to a corresponding plurality of keyers. The sequential enabling is separately controllable by an arpeggio circuit, a glissando circuit, and a strum circuit. The digital circuitry includes an octave counter and a tone counter both of which are stepped by a quadrature clock to sequentially enable the gates. The quadrature clock can be stopped to cause a count to be held under control of multivibrators which adjustably control the tone interval and the repeat interval. The repeat multivibrator can be automatically synchronized under control of a key down detector or a rhythm generator.
