Plenio 0.3 ships: local AI music production in ComfyUI with score editor, stems and mastering

Developer jplenio released Plenio Music Production System 0.3, a fully local music production pipeline running as ComfyUI nodes: a local LLM writes the song from a description, YuE2 or MiniMax Music 3 performs it, and Plenio handles mixing, mastering and export — no cloud, no API keys, no extra Python packages.
Version 0.3 turns "prompt in, song out" into a DAW-style workflow:
- Real score editor: edit YuE2's melody as piano roll, notation or ABC text, with multi-note moves, chord symbols, bar-level operations, undo/redo and MIDI I/O
- Stems & effects: split finished songs into vocals/drums/bass/other plus residual; per-stem faders, compression, reverb and delay buses; export 24-bit FLAC stems
- Sound quality: Refine upsamples to 48 kHz with the UniverSR super-resolution model; a draggable EQ with spectrum display; mastering to -14 LUFS / -1 dBTP
- What you see is what the model gets: review title, style, lyrics and score before rendering, with nothing rendered until approved
Six templates cover new songs, covers, MiniMax songs, enhance & master, a DAW-style blank-score mode, and a system check. Install via ComfyUI Manager (comfyui-plenio-music); Refine and Stems are still experimental.
