Every idea, resolved.

Make the idea land.

Write, shape, and share music in one open studio, with on-device AI beside you.

Open web composerDownloadDocs

Start anonymously and keep composing offline. The public web app has no hosted backend, so account, sync, collaboration, and stems features show their existing unavailable states.

A real capture of Cadence in Write view.

Stay in the musical moment.

Cadence keeps writing, arranging, mixing, and sharing in one focused workspace, so the tool never outruns the idea.

Write at full speed

Shape notes on a responsive piano roll with transport, quantize, velocity, and automation close at hand.

Move into the mix

Balance tracks, add effects, automate changes, and keep the same project moving from sketch to playback.

Let the work travel

Save portable projects, export standard formats, or send a listen link without rebuilding the session.

One project, many ways forward.

Work in the view the track needs, then move it into tools other musicians already use.
