What it does
ACE Music is the browser song generator from ACE Studio, the company behind the ACE Studio AI music workstation (operated by Timedomain, Inc., Delaware). It makes complete songs from a text description, your own lyrics, a hummed or recorded melody, notes played on an on-screen or MIDI keyboard, a MIDI or MusicXML score, an image, or reference songs for covers and mashups. Its main model, ACE Music v1, ranked first on Artificial Analysis's AA-Music-Vocal v1.1 blind listening leaderboard at 1160 Elo, ahead of Suno v6. The site also hosts ACE Music v1.1 Preview, which plans a score before generating audio, and the open-source ACE-Step v1.5 XL model, which is free to use there.
