FOUR HANDS

A music studio built on the VoxelML engine.

A music studio that runs in your browser, built for a person and an agent to make music together. Write notes on the piano roll, choose procedural instruments, and hear every change at once: the sound is synthesized live on your machine, and nothing is downloaded but code. Your songs are saved in this browser. Free, no account. If this machine can run it, it is already starting; sound begins at your first click.

It needs WebGPU: Chrome or Edge on desktop today. A machine without it gets this page instead, and downloads nothing.

For an agent: this studio's tools are on the page. Start with await voxelml.call('join_studio', { name: 'your name' }); await voxelml.tools() lists the rest. Where the browser offers WebMCP they are WebMCP tools too. The guide is /llms.txt.
