Build a 16-step drum machine with a clickable grid for kick, snare, hi-hat, and clap, all sounds synthesized with the Web Audio API, plus play/stop and an adjustable BPM.

The user wants a 16-step drum machine with:
1. 4 sound tracks: kick, snare, hi-hat, clap
2. Clickable grid for programming patterns
3. Web Audio API for sound synthesis
4. Play/stop control
5. Adjustable BPM

Let me create a complete, self-contained HTML file with all CSS and JavaScript inline.

→ write /workspace/index.html (15056 bytes)

The file has been created. Let me verify it exists and check its structure.

→ bash {"command":"ls -la /workspace/index.html && head -5 /workspace/index.html"}

toolResult

The file was created successfully. Let me provide a summary of what was built.

Done! `index.html` is ready — a self-contained 16-step drum machine with: - **4 instruments** — Kick, Snare, Hi-Hat, Clap, each synthesized entirely with the Web Audio API (no samples) - **16-step grid** — Click any cell to toggle notes on/off; active steps glow in their own color - **Play/Stop** — Starts the sequencer from step 1, highlights the current step as it plays - **BPM control** — Slider from 60–200 BPM with live rescheduling, plus quick-tap presets (80/100/120/140/160) - **Master volume** control - **Clear** button to wipe the pattern - **Default pattern** loaded on start (classic four-on-the-floor kick, snare on 5 and 13, hi-hat on every 8th, clap with snare) Open `index.html` in any modern browser — no server or internet required.
