Live harmonies for a voice, a horn, or any single melodic line. The Harmonizer listens to the pitch at its inlet and grows up to four extra voices around it, each one the same performance shifted to a new note - vibrato, phrasing and all. Harmonies only sound while the tracker hears a clear pitch, so breaths and consonants pass clean.
In MIDI mode you play the harmony: hold a chord at the MIDI inlet and the voices pitch the incoming line to the held notes - sing one note, sound the whole chord, move your hand and the stack follows. In SCALE mode it runs hands-free: set Key and Scale, give each voice an interval in scale degrees (+2 is a diatonic third up, -3 a fourth below, +7 the octave) and the harmonies stay in key wherever the melody goes.
Glide decides whether the voices leap to new targets or slide; Humanize lets each voice drift a few cents at its own slow rate so the stack stops sounding like one machine; Spread fans the voices across the stereo field around the dry line.
Parameters
| Mode | MIDI plays the targets from held notes; SCALE derives them from Key, Scale and the Voice intervals. |
| Key / Scale | the tonal home for SCALE mode. |
| Voice 1-4 | each voice's interval in scale degrees, with its Level knob beside it. A voice at zero level rests. In MIDI mode the held notes take over and the levels rest at full. |
| Glide | how long a voice takes to reach a new target note. |
| Humanize | slow per-voice detune drift, up to about 14 cents. |
| Spread | stereo width of the harmony stack. |
| Mix | one crossfade from the incoming line alone to the harmony bed alone, equal-power in between. Halfway keeps the lead in front with the stack behind it; full wet leaves only the harmonies - which also means silence wherever no harmony sounds (no held notes in MIDI mode, or an untracked source). |
