ABSTRACT:
An automatic playing device for a musical instrument includes a memory unit which stores a plurality of discrete states, e.g., patterns of key actuation of a keyboard, which can be serialized and combined with or substituted for manual keying information from a keyboard or other control device. Combining and substituting are controlled by the actuation of one or more switches by a human operator. The operator can advance through the stored pattern by actuating a single key or by playing a simple sequence of notes on a keyboard.
