Harmony Engine from Antares Audio Technologies is a real-time harmony-creation plug-in that lets you quickly produce realistic vocal arrangements and explore harmonic alternatives from a single vocal line or monophonic instrument track.
The Harmony Engine gives you four high-quality harmony voices with independently adjustable vocal character, vibrato, and pan settings for realistic or extreme effects. Five channels of the Antares Choir vocal multiplier let you turn each harmony voice into 2, 4, 8, or 16 individual unison voices for thick unison choir effects. Each harmony voice can be processed through Throat Modeling technology, a physical model of the human vocal tract that produces natural-sounding performances.
Powerful control options abound. In fully automatic mode, set the key and harmony voice intervals and let the plug-in do the rest. MIDI mode lets you directly play the four harmony voices with your MIDI controller, as if they were voices of a synth or sampler.
Harmony Engine is compatible with the Auto-Key plug-in (available separately). Auto-Key is designed to save you countless hours in the studio by automatically detecting the key and scale of your music and sending that information to Harmony Engine with a single click.
