Abstract
A harmony generating circuit generates high harmony signals in response to coincident lower manual accompaniment signals and upper manual melody signals. Gating circuitry responsive to coincident inputs from accompaniment chords played on the lower manual and melody notes played on the upper manual generate harmony notes on the upper manual which correspond to the accompaniment notes played on the lower manual but are above the melody notes and approximately within one octave of the melody notes.
Claims5
A harmony generating system for use in an electronic organ having a lower manual for generating lower manual keying signals and an upper manual for generating upper manual keying signals, said harmony generating system comprising:
- first means including output terminals connected to said upper manual for coupling said upper manual keying signals to said output terminals;
- second means connected to said upper and lower manuals and to said first means for generating harmony signals in response to said upper manual keying signals and said lower manual keying signals, said harmony signals directly corresponding to said lower manual keying signals, being one octave above said upper manual keying signals and being provided on said output terminals;
- and
- third means connected to said second means for controlling the relative magnitude of said upper manual keying signals and said harmony signals such that said upper manual keying signals are greater in magnitude than said harmony signals to accentuate the musical notes played in response to said upper manual keying signals.
