Plenio 2.0: open-source ComfyUI suite turns an idea into a mastered song, now with VST3
Vivid_Promise1700 · reddit · 2026-11-14
Plenio 2.0 is a free, open-source (Apache-2.0) song production suite inside ComfyUI: a local LLM writes lyrics, YuE2 or MiniMax Music 3 sings them, and you get a mastered FLAC plus cover art, timed lyrics and sheet music — all local.
Highlights:
- Plenio Setup detects your GPU, plans model files, verifies SHA-256, and runs a test song first
- All models default to auto, so templates port across machines untouched
- Song API v2 + MCP server: restart-safe jobs; ask Claude Desktop or Claude Code for a song and it plays in the Plenio Player
- The Director generates visuals synced to beats/bars; a new VST3 plugin brings takes, stems and MIDI onto DAW tracks
39 nodes, 6 templates, 250 genre templates; tested on ComfyUI 0.41/0.44. Install: comfy node install comfyui-plenio-music. Note YuE2 weights are CC BY-NC 4.0 (non-commercial).
