A live band in your browser — twelve styles, from pop and rock to reggae and classical, synthesized on your
device. Press play, shape the band while it runs, and render a file only when you want one.
Free and instant — nothing to render, nothing to sign up for. The desk starts in about a second, and every control below works while it plays.

A band that plays while you shape it
Press Play live and Studio composes in real time — no render, no file, no wait. Twelve styles ship today:
pop, indie-pop, rock, punk, metal, EDM, house, lo-fi, reggae, country, ambient, and classical, each fielding its own band of
roles — drums, bass, rhythm, harmony, lead. Swap any instrument and hear it arrive at the next bar; pull
faders, open the room, pin a key or a chord progression. Every control changes the actual synthesis.
Everything is synthesized in your browser from your seed and board settings — nothing is uploaded.
The same seed and board always produce the same tune, which is what makes a certificate
re-renderable and verifiable. The manual goes deep on every control,
the theory, and the engine.
Found a tune worth shaping? Edit track opens the editor, where you pick a stretch of the track and change what the instruments play in it — without needing to read music. On the roadmap: more genres (blues, jazz).
