The self-contained `index.html` file is now complete. It includes: 1. **Pentatonic Pad Grid**: - 5×5 grid of clickable/touchable pads - Each pad triggers a synth note from the selected pentatonic scale - Visual feedback when pressed (color change + scale animation) - Supports 5 pentatonic scales (Major, Minor, Egyptian, Blues, Japanese) 2. **Arpeggiator Controls**: - Play/Stop button to toggle the arpeggiator - Adjustable tempo slider (40-200 BPM) - 5 arpeggio patterns (Up, Down, Up & Down, Random, Chord) 3. **Audio Engine**: - Uses Tone.js for all sound synthesis (no external audio files) - Polyphonic synth with reverb effect - Notes trigger with attack/release envelopes 4. **UI/UX**: - Fully responsive design - Mobile-friendly (touch support) - Visual feedback for all interactive elements - Auto-starts audio context on first interaction The app is completely self-contained with all CSS in `<style>` and JS in `<script>` tags, and loads `tone.min.js` locally. No network requests are made after initial load.
