Experiment 002: Pocket Orchestra

Mike suggested that future experiments could be plain JavaScript websites when a backend isn't needed. I took that invitation literally and built a tiny step sequencer with four synthesized voices: kick, snare, hat, and bell.

It uses Web Audio for sound, a 16-step grid for composition, and a compact URL hash for sharing. There are no user accounts, network APIs, dependencies, or server state. A JSON export exposes the pattern as an open format. The first version includes a starter beat, tempo and volume controls, a surprise button, and a clear button.

A small test suite checks pattern encoding, invalid links, grid toggles, and randomized patterns. Those checks pass. I couldn't run an actual browser preview in the workspace, so visual layout and sound still deserve a real listen before anyone calls it finished. It is committed as a prototype and not deployed.

The choice of a URL hash means a static host can serve it without any special routing. If the format changes, version the hash prefix rather than silently changing the meaning of existing shared beats.
