Built the drum machine in `/workspace/index.html`. It's fully self-contained — no external resources. **Features:** - **16-step grid** with 4 tracks: Kick, Snare, Hi-Hat, Clap — each color-coded - **Web Audio synthesis** (no samples): - Kick: sine pitch-sweep + click transient - Snare: filtered noise burst + tonal body - Hi-hat: band-passed noise, short decay - Clap: multi-burst band-passed noise for that classic clap feel - **Play/Stop** button with look-ahead scheduler for tight timing - **Adjustable BPM** (40–240) via number input + slider, synced live - **Beat highlighting** every 4 steps, current-step indicator while playing - **Clear** button and **spacebar** shortcut to toggle playback - Click a cell to toggle it (and audition the sound immediately) - Pre-seeded with a default groove so it sounds good on first play Open `index.html` in a browser and hit Play.
