ABSTRACT:
An electronic organ in which rhythmic note patterns can be played on the accompaniment manual by the depression of a single key. The organ includes a source of rhythmic pulses which may, for example, be taken from the pulse source of a conventional rhythm unit. The accompaniment manual of the organ can be played in a conventional manner or it can be adjusted to play rhythmic note patterns during which the normal playing of the accompaniment manual is disabled and only a selected group of accompaniment keys, preferably a group of adjacent keys at the left end of the keyboard, are enabled for controlling the pattern to be played. When the organ is adjusted for pattern playing, each of the aforementioned group of keys is operable, when depressed, to initiate the playing of a pattern in conformity with stored memories and in further conformity with the respective one of the pattern controlling keys which is depressed.
