Done! The beat maker is now mobile optimized with:

- Responsive text sizing using `clamp()`
- Touch-friendly controls with larger hit targets
- Flexible grid layouts that stack on mobile
- Horizontal scrolling for the sequencer if needed
- Media queries for tablets (768px) and phones (480px)
- Better spacing and padding for small screens
- Prevented zoom on input focus
- Touch action optimization for better responsiveness

**Next Ideas:**
1. **Preset Patterns** - Add save/load buttons with pre-made beats (trap, house, dubstep)
2. **Recording & Export** - Record your sessions and download as WAV/MP3 files
