OpenSuno: a local AI music studio for YuE2

Everything you need to make a song

A full browser studio around YuE2, the open lyrics-to-song model. Everything runs locally; your recordings never leave your computer.

Songs from lyrics

Lyrics plus a style line. The model can write a chord-annotated score first for structured songs. Instrumental mode, voice choice, and up to 8 versions per run.

Cover your recordings

Upload a song, keep its melody (and chords), and let the model arrange it in a new style with in-tune chords on every bar.

Extend and edit

Extend a song, regenerate from any bar, or edit the arrangement at the score level: style, tempo, harmony and structure.

Community LoRAs

Two stackable slots: one changes what is written (genre, artist style), one changes the sound. A curated catalog downloads in one click.

Style help

73 style presets with blending, a style builder, optional AI style suggestions, section-tag picker, lyric search and automatic album art.

Your hardware

Apple Silicon via MLX, Windows and NVIDIA via CUDA. Render on another machine's GPU with the render node.

Covers that keep the song

SheetSage2 and MERT-v2 transcribe the melody; YuE2 arranges the rest around it.

Arrange with the model fills chords and instrumental lines in the new style.
Vocal Range moves the melody to where the chosen voice sings it.
Continue this recording keeps the audio up to a point and writes what comes next.
Sound LoRAs like the Real-audio decoder v9 give a fuller, more produced render.
