Abstract
A circuit for an electronic organ for producing rhythmic patterns of notes in accordance with the selection of a chord in the accompaniment manual. The organ includes an accompaniment manual and a solo manual, either or both of which may be electronically scanned to develop a multiplexed data stream, and a chord generation circuit controlled by the accompaniment manual for sounding groups of notes in the accompaniment voices in response to the depression of one of the selected group of keys on the accompaniment manual. The circuit according to the present invention automatically sounds notes of the solo manual in a rhythmic pattern in response to the depression of one of the group of accompaniment manual keys by developing a logic pulse at the beginning of the top octave scan which is delayed in time to correspond to the time slot of the chord root note and subsequent notes of the chord. The amount of delay is controlled by pre-programmed patterns preselected by the musician.
