ACE-Step UI at a glance
Checked 16 Oct 2026ACE-Step UI is a React and Express front end that talks to a locally running ACE-Step 1.5 Gradio API. It adds a Spotify-like library and player, lyrics editor, instrumental mode, covers, repainting, Demucs stem extraction, an AudioMass editor and a music-video maker. You must install ACE-Step 1.5 separately, plus Node.js 18 and FFmpeg; it needs an NVIDIA GPU with 4 GB+ VRAM (12 GB+ with the planner). The README says MIT, but the repo has no licence file, so the licence is unclear. Last push June 2026, two contributors.
