Secret Weapon of the Pros

Harmony Engine, a favorite vocal effect heard on records from Billie Eilish, Diplo, Lady Gaga, HAIM, and more, makes it easy to add lush harmonies to your vocal tracks.

Harmonies as Unique as You

Use up to 4 voices in any given key, each with its own unique timbre, vibrato, panning, and octaves, giving you full control of each individual harmony.

Harmony of One

Produce professional-quality harmony arrangements from a single vocal, or experiment with monophonic instrument tracks to create new sounds.

A Creative Choir

With our impressive built-in Choir technology, you can enrich all 4 harmonies with 2, 4, 8, or even 16 voices. Customize them further using individual timbre, vibrato and stereo spread controls.

Handmade 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.

Plays Well with Others

Harmony Engine is compatible with every major DAW and seamlessly integrates with Auto-Key 2 and Auto-Key Mobile, which means you'll never worry about finding the key, scale, or tempo of your music again.
