A step sequencer is the beating heart of electronic music, and this one lets you build a drum pattern by tapping cells on a grid. Each row is an instrument — kick, snare, hi-hat, open hat, clap, tom, rim and cowbell — and each column is a step in the bar. Switch cells on, press play, and the pattern loops. Start from a preset like four-on-the-floor or boom bap, hit Random for inspiration, or build from an empty grid.
Beyond the basics you get a proper mixer: per-track volume and mute, a master level, and a swing control that delays every off-beat sixteenth for that classic shuffle feel. All eight drum sounds are synthesized live with the Web Audio API — no samples to download — and you can render your pattern offline and download it as a real WAV file.
