ACE Studio

ACE Studio is an AI vocal synthesis tool that turns a MIDI melody or piano-roll input and a set of lyrics into a sung vocal performance. It ships with over 140 AI singer voices spanning pop, rock, opera, hip-hop, R&B, J-Pop, C-Pop, and other styles across multiple languages, and it lets producers shape the result with phoneme-level control over pitch, vibrato, breathiness, tension, and falsetto rather than just accepting a flat synthesized take. It also supports voice cloning from uploaded vocal samples for creators who want a custom or consistent voice across tracks.

It's built for independent musicians, songwriters, and producers who need a finished or demo vocal without hiring a singer, whether that's for a scratch track to pitch a song, a full commercial release, or scoring work where a human vocalist isn't practical. Beyond single-voice lines, it includes a Choir Mode for stacking multi-voice arrangements and an Ensemble Mode for layered instrumental backing, plus AI virtual instruments that generate expressive performances from MIDI, which pushes it past a plain text-to-singing tool toward a broader vocal and arrangement production suite.

What sets it apart from most singing synthesizers is the depth of manual control over expression combined with the size and stylistic range of its voice library, and the built-in voice cloning for custom vocal models. It runs as a subscription product (with a free trial), with paid tiers unlocking commercial usage rights on the voice library.
