Open-source local AI music studio on ComfyUI: songs, stems, beat-cut videos

SenzubeanGaming · reddit · 2026-08-21

A developer open-sourced AIPLAY Studio, a desktop AI music studio built on top of ComfyUI. Rather than reimplementing anything, it launches ComfyUI as a separate process and submits graphs over its HTTP API, rendering music with MiniMax Music 3.

The standout: all pipelines ship in workflows/ as ordinary API-format ComfyUI JSON, drag-and-drop ready. The values aren't defaults — they were arrived at with measurement scripts (shipped in scripts/) so anyone can re-run and disagree.

Features include: songs from style description + lyrics, idle-time cover art generation, stem separation, word-level timed lyrics, video clips via LTX 2.5 or MiniMax H3, a multi-track editor that cuts to the detected beat grid, and overnight batch runs. Newest is audio-reactive video: reference images cross-fade in sync with the track's detected peaks (built on the GPL-3.0 ComfyUIYvann-Nodes, run on a second ComfyUI due to license conflict). Ships no model weights; each capability shows size and license before download, one region-locked model is labeled as such. Apache-2.0, runs offline after weights download, measured on a 4070 Ti SUPER.
