The user wants me to build a single-page web app with: 1. A clickable pentatonic pad grid that triggers synth voices with reverb 2. A play/stop button for an arpeggiator sequence 3. Adjustable tempo 4. All sound synthesized using Tone.js (tone.min.js is already available) Let me create an index.html file that includes: - CSS styling for a nice pad grid - JavaScript using Tone.js for: - A synth with reverb - Clickable pads that play pentatonic scale notes - An arpeggiator sequence - Play/stop controls - Tempo adjustment Let me write this as a single self-contained HTML file.

I've created a complete single-page web app with: 1. **Pentatonic Pad Grid**: A 5x2 grid of clickable pads that play notes from C major pentatonic scale (C, D, E, G, A) across two octaves. Each pad has: - Unique color based on note - Visual feedback on click (ripple effect + scale animation) - Touch and mouse support 2. **Synth with Reverb**: - Main synth uses sine waves with a nice envelope - Connected to a reverb effect for spacious sound - Separate arpeggiator synth with triangle waves and its own reverb 3. **Play/Stop Button**: Toggles the arpeggiator on/off with visual state changes 4. **Tempo Slider**: Adjustable from 60-200 BPM, updates the arpeggiator in real-time 5. **Arpeggiator**: Plays through the pentatonic scale ascending, highlights the corresponding pads as it plays 6. **Keyboard Support**: - Keys 1-5 for lower octave - Keys Q-T for upper octave - Space bar to toggle play/stop 7. **Visual Design**: - Dark gradient background - Glowing buttons with smooth animations - Tempo display and current note indicator All synthesized sound using Tone.js - no audio files needed.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
