ACE Studio
ACE Studio is an AI music production platform built around singing voice synthesis. You give it MIDI and lyrics and it returns an expressive vocal performance, with 140+ voices across 8 languages, voice cloning, AI instruments, stem splitting and a DAW plugin that brings the whole thing into your session.
- MIDI-and-lyrics input means the output stays fully editable rather than take-it-or-leave-it
- ACE Bridge with ARA support puts the vocal inside your session instead of a browser tab
- AAX support signals the developers are aiming at studios, not only hobbyists
- Voice count and language spread are unusually broad for singing synthesis specifically
- It cannot rescue a weak melody — everything upstream of the notes is still your job
- Interpretation and vocal texture remain well short of a good human singer
- Voice cloning carries likeness and consent obligations the tool cannot settle for you
