off the clock

The Groovebox.

Not everything here has to be infrastructure. Tap out your own beat on the sequencer (or start from a preset), pick a key and a scale, then hold down and drag across the grid — left to right changes the note, bottom to top changes the character. Switch the voice to hold for gliding drones or chords for stabs, hit record to capture your groove as an audio file, or copy a link that carries the whole thing. Every sound is synthesised live in your browser with the Web Audio API — no libraries, no samples, nothing to install.
