Controls

• Voice 1 Interval−12 to +12 semitones — Interval of voice 1 in semitones
• Voice 2 Interval−12 to +12 semitones — Interval of voice 2 in semitones
• Voice 1 Level−48 to 0 dB — Level of voice 1
• Voice 2 Level−48 to 0 dB — Level of voice 2
• Detune0 to 30 cents — Opposite detune of the two voices for a natural, separate-performer feel
• Delay0 to 80 ms — Delay of the voices (voice 2 is delayed 1.37× longer)
• Spread0 to 100% — Pans voice 1 left and voice 2 right
• Mix0 to 100% — Equal-power dry/wet: 0% = original only, 50% = both at −3 dB, 100% = harmony voices only
• ModeSemitones / Scale / MIDI — How the voices find their notes: Semitones uses the fixed intervals, Scale turns the intervals into steps of the chosen key and scale above or below the note you sing (so harmonies stay in key), MIDI makes the voices sing the notes you hold on a MIDI keyboard
• KeyC / C# / D / D# / E / F / F# / G / G# / A / A# / B — Key of the scale used in Scale mode
• ScaleMajor / Minor / Dorian / Mixolydian / Harmonic Minor / Pentatonic Major / Pentatonic Minor — Scale used in Scale mode: Major, Minor, Dorian, Mixolydian, Harmonic Minor, Pentatonic Major or Pentatonic Minor
• Formant PreserveOff / On — Shifts the voices with pitch-synchronous grains that keep the character of the vowels instead of the chipmunk effect (the voices come about 40 ms later)

Best uses

• Thirds and fifths on lead lines
• Octave doubling on guitars and synths
• Wide stereo harmony beds

Properties

Signal chain: Input (summed to mono) → 2 Crossfading Delay-Line Pitch Shifters (50 ms window) → Detune + Delay → Equal-Power Spread → Equal-Power Dry/Wet Mix → Output. Fixed intervals (no key detection); Mix at 100% outputs only the harmony for printing to its own track; zero latency.
