ABSTRACT:
An electronic musical instrument having two keyboards is disclosed in which chords detected on the accompaniment keyboard are used to vary the selected tone color of the tones played on the solo keyboard. The solo tones are synthesized by means of a Fourier transform using a set of harmonic coefficients. Selected harmonic coefficients are scaled in magnitude in response to the chord type detected from the notes played on the accompaniment keyboard.
