Questions before you start
What harmonies do I get?
A harmony a third above your melody, one a fifth above, and a ready-mixed blend of your vocal with both harmonies tucked underneath.
Are the harmonies key-aware?
They are fixed chromatic intervals (harmonizer-pedal style), which suits most pop and rock melodies. Key-aware diatonic harmonies are on the roadmap.
Can I mix the harmonies myself?
Yes — the third and fifth come as separate downloads alongside the blend, so you can balance them however you like.
What input works best?
A solo vocal. Full-mix uploads will harmonize everything in the track, which is usually not what you want.
