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 single-page web app - a 16-step drum machine with:
1. Clickable grid for 4 sounds: kick, snare, hi-hat, and clap
2. All sounds synthesized with Web Audio API (no external samples)
3. Play/stop controls
4. Adjustable BPM
5. Everything in one self-contained index.html file

Let me build this step by step. I need to synthesize:
- Kick: low frequency sine wave with quick decay
- Snare: combination of sine wave and noise
- Hi-hat: high frequency noise with very short decay
- Clap: burst of filtered noise

I'll create a complete, polished drum machine.

The file has been written successfully. Let me verify it's there and looks good.

Done! The `index.html` file is ready at `/tmp/ws/index.html`. Here's what's inside: **Features:** - **16-step grid** with 4 rows: Kick, Snare, Hi-Hat, Clap — click any cell to toggle steps on/off - **All sounds synthesized** via Web Audio API (no samples, no network): - **Kick** — sine wave pitch-swept from 160 Hz → 40 Hz with a square-wave click - **Snare** — noise burst + triangle tone + filtered pop tail - **Hi-Hat** — filtered white noise (high-pass + band-pass) with short decay - **Clap** — dual bandpass-filtered noise bursts for a realistic layered clap - **Play/Stop** buttons with playhead indicator sweeping across the grid - **Adjustable BPM** slider (40–220) - **Per-instrument volume** sliders - **Preset patterns**: Basic Beat, Hip Hop, Techno, Disco, and Clear - **Keyboard shortcuts**: Space = play/stop, Q/W/E/R = preview individual sounds
