ABSTRACT:
An electronic organ having solo, accompaniment, and pedal keyboards, or manuals, and adjustable into different modes of playing for at least the accompaniment keyboard.
In a first playing mode, the accompaniment keyboard plays in a conventional manner with each key of the keyboard which is depressed actuating a respective keyer.
In a second selectable playing mode, the keys of the accompaniment keyboard are disabled for actuating keyers in a conventional manner and, instead, a selected group of the keys, referred to as "chord playing" keys, are made effective for playing chords by having each of the chord playing keys actuate a respective group of keyers while the key is depressed.
In a third playing mode, the keys of the accompaniment manual are disabled for actuating respective keyers and, instead, the same group of "chord playing" keys referred to above are enabled for actuating the keyers pertaining to respective chords singly, or in groups, sequentially at predetermined time intervals. At this time further, or even, different notes can be sounded.
