How to use it
Pick a voice with Lead, Bass or Drums, then hit the pads with your mouse or the number keys 1 to 8. The letters A S D F G H J K do the same job for people who prefer the home row.
To record, arm a track with REC, play a pattern, then press REC again to close the loop. It caps at 30 seconds. Hit PLAY to loop it, then stack the other two tracks on top. CLEAR wipes a track and starts it fresh.
Every sound is synthesised on the fly. There are no samples, no presets and no audio files.
Why I built it
I wanted to prove the Web Audio API can do a lot with a little. A drum kit, a bass line and a lead all come from oscillators and a single buffer of noise, tuned by ear to sit somewhere between a Game Boy and a Pocket Operator.
It is deliberately self contained: one page, no framework, no third party libraries. If it ever breaks, it breaks in the open.
