This module produces polyphonic pitch control voltage signals via S-Poly connections that represent the commonest three note chords.
The left/red outputs produce the voltages required for diatonic triads in a major scale.
The right/blue outputs produce the voltages required for diatonic triads in a minor scale.
The KEY IN socket is used to control which key the chords are in. If no voltage is connected then the key defaults to C.
Diatonic triads are three note chords that use only notes in a scale.
The notes within the chord are the root, third and fifth.
The most basic chords are I, IV and V. These are the standard chords used in the simplest three chord song.
The commonest use is to feed these signals into the Progressions module to build up chord progressions.
