Songs from words, on your own machine.

Five rooms, one studio

The Creator makes the song, the Writer writes it with a chat model, the Refiner finishes it, the Librarian keeps every take, and the LoRA Trainer teaches YuE2 your own songs. A guide for every room is inside the studio.

Creator

Style, lyrics, planning mode, decoder, sliders, LoRAs on a road from green to red; the take with its score, seeds and everything to make it again.

Writer

Songs as documents with versions, text profiles, and a chat model of your own (or OpenRouter) that drafts and revises with you.

Refiner

Spectrum, artifacts, debuzz, a lyrics check by Whisper, stems, remaster, upscale; one chain runs them all.

Librarian

Every take in workspaces: searched, liked, noted, locked, given artwork, sent to your DAW; a trash that gives back.

LoRA Trainer

Adapters from your own songs: the set, the run, both halves' curves explained, the epochs worth hearing first.

The cheat-sheet ♪

200 instruments probed and judged by ear: what YuE2 really plays, what it plays thinly, what it does not know.

What makes it a studio

Not one more model wrapper: a workstation around the model, open to the bone, every change numbered and documented.

• Whole songs, up to eight minutes. A 6:12 song in 126 s; a 7:25 song with its score first in 198 s, on one RTX 3090.
• The score first, and yours to edit. YuE2 writes the melody and chords as ABC before a note sounds: change them, transpose them, bring your own score or MIDI, and the song follows it.
• Two seeds, not one. Keep the song (the music seed), hear it rendered anew (the sound seed).
• Your own sound. LoRA training on your own songs, in the studio, unquantized (bf16), with telemetry that tells you which epochs to hear first.
• Post-production, all local. Stems (BS-Roformer, htdemucs), debuzz, remaster, upscale (UniverSR), a lyrics check by Whisper.
• Into your DAW (experimental). A REAPER project with the stems, the score as MIDI, the sections and the lyrics on the timeline; DAWproject for Waveform and Bitwig.
• A writer that knows the engine. The style as short tags, the most important first: the way YuE2 follows best.
• Several GPUs, several jobs. Synthesis on one card, training on the others; with one card the page tells you what waits.
• For scripts and agents. An API (OpenAPI 3.1) and an MCP server on your machine and your network.
• Your language. The page whole in English, Russian, Ukrainian, Belarusian, Greek, Spanish and Italian.

A guard against garbage

When the music half writes a broken score (adapters pushed too far do that), the engine stops the run before any music is built on it, in seconds, and says why: which adapters, how far past their limits, what was written.

Strengths sit on measured roads; stacked adapters share a measured ceiling.

Its own LoRA trainer

The studio trains adapters itself, on unquantized bf16 weights. Against Ostris' AI-Toolkit on the same set, the music half's loss agrees epoch by epoch within 0.015.

Rank 16 on 148 songs: 2.1 s a step in 12 GB. Rank 32 on 42 full songs: 6.7 s a step in 18 GB.

Ruach Studio and SUNO, honestly

Every week a video says some model kills SUNO. This is not a model: it is a workstation around one. Here is where it wins, and where it does not (yet).

What you need

What comes next

2.0.0-rc1 is the studio we make our own songs in every day. These are the larger pieces on their way, for rc2 and after.

• The Artist room. Covers in three shapes at once from one seed (1:1 for the album, 16:9 for a video, 9:16 for a short), the title and the artist written on them, the versions of each take's picture.
• Five more languages. Chinese, French, Portuguese, German and Japanese; the right-to-left ones once the page itself runs right to left.
• The Writer's models with their prices, from OpenRouter's list, as you type.
• Calmer rooms. Every button that cannot be undone behind a dialog, the inline notes as tips, one shape for the icon buttons.
• A voice's kind in the Trainer, measured on speech and on singing.
• A desktop app. An installable page (PWA) first, then an Electron app that starts and stops its services itself.
• A score editor as a DAW has one. A piano roll, a chord lane, the lyrics over the notes, a MIDI keyboard to play ideas in.
• Native plugins for REAPER, Waveform and Bitwig, once the studio has found its people.
