Harmony Engine is a real-time harmony generating plug-in that lets you produce professional quality harmony arrangements from a single vocal or monophonic instrument track.

Whether you're an experienced arranger, a songwriter looking for the perfect backup vocal, or a producer experimenting with unique effects, Harmony Engine gives you new ways to create the harmony parts you hear in your head. It offers a variety of control modes, from fully automatic to individual control of every note.

Harmony Engine features four high-quality harmony voices with independently adjustable vocal character, vibrato, and pan settings for realistic or extreme effects. And five channels of our Choir vocal multiplier lets you turn each harmony voice into 2, 4, 8, or 16 individual unison voices.

Harmony Engine provides all the tools you need to produce lush and convincing harmonies. Meticulously craft your own vocal arrangement note-by-note, perform your harmonies with your MIDI controller, or simply choose the chords and let Harmony Engine do the rest.

Auto-Tune EFX+ is a versatile new vocal production tool, which combines the core features of Auto-Tune with the powerful Auto-EFX multi-effects rack, and Auto-Motion pitch-shifting melodic pattern generator.

Auto-Tune EFX+ includes professional quality Auto-Tune pitch correction with low latency processing for real-time performance on stage or in the studio.

Fully adjustable Retune Speed and Humanize parameters let you fine-tune the desired effect for your tracks, from transparent pitch correction to the iconic Auto-Tune Effect.

And compatibility with Auto-Key (sold separately) means never having to worry about finding the key of your music before tuning. Auto-Key detects the key and scale and sends that information to Auto-Tune EFX+ with a single click.
