A MIDI chord generator. Every note you play becomes a chord: Chord adds fixed intervals above it and sends the result on to an instrument. It makes no sound of its own.
When you release a key, Chord releases every note that key produced, so held chords never leave notes hanging. Added notes that would fall outside the MIDI range are left out rather than wrapped into another octave.
The keyboard picture shows which notes a middle C would produce with the current settings. It is a reference, not a live display of what you play.
Place Chord before any instrument and play a single-note line. Start with Power fifth for a thick, guitar-like doubling, then try Minor triad with Spread at +1 for an open voicing.
Every noteOn looks up the current chord mode's interval set ([0, 4, 7] for major, [0, 3, 7] for minor, and so on) and emits a noteOn for each interval, offset by the spread octaves. The root is always emitted at original velocity; added voices are scaled. A noteOff for the root releases every voice the chord expanded into. Notes outside MIDI range 0–127 are suppressed.
