BAP Studio: An MPC-style drum machine that runs in a browser tab

I wanted a drum machine I could open in a tab and start playing straight away - no install, no account, no sample library to download first. So I built BAP Studio. It is 16 velocity-sensitive pads across four banks, a 16-step sequencer with per-step velocity and swing, four patterns that chain into a song, and a sampler that takes any audio file or mic recording, finds the transients and lays the chops across the pads. Every sound is synthesised in the browser, so there is nothing to install and nothing to wait for. You can export a WAV, a MIDI file, or a link that rebuilds your beat exactly as you left it. Quickest way in: press Space to start the loop, then hit Z, C and A. Most people have something going in about a minute. Would love to hear what you make with it.
