I'll create a single-page web app with a pentatonic pad grid and arpeggiator using the provided tone.min.js library. Let me build this with CSS in a <style> tag and JS in a <script> tag, all in one index.html file.

I see that tone.min.js is available. Now I'll create a single-page web app with a pentatonic pad grid and arpeggiator functionality.

I've created a complete single-page web app with a pentatonic pad grid and arpeggiator using the provided tone.min.js library. The app features: 1. A 5-pad grid with C major pentatonic notes (C, D, E, G, A) 2. Each pad triggers a synth note when clicked with a sustain/release envelope 3. A tempo control slider (60-180 BPM) that adjusts the arpeggiator speed 4. A play/stop button that toggles the arpeggiator sequence 5. Visual feedback with active pad highlighting 6. Reverb effect on all sounds 7. All code in one self-contained index.html file with no external dependencies The app runs fully sandboxed with no network requests, using only the provided tone.min.js library. The synth uses a sine oscillator with a rich envelope and reverb for a pad-like sound.
