ABSTRACT:
The present invention relates to a process and apparatus for use in musical instruments. In particular, the invention is useful for identifying a chord played on a keyboard of a musical instrument, such as the accompaniment manual of an electronic organ, and for identifying the root and the type of chord being played. Pursuant to the invention, a microprocessor used in conjunction with the instrument selectively causes the associated circuitry of the pedal and/or accompaniment keyboard of the musical instrument to play automatically in an appropriate octave either the identified root or a sequence of notes which is compatible with the identified root and chord. A pedal override feature is also provided which overrides the chord identification invention when the musician plays one or more pedal notes.
