I'll create a single-page web app with a pentatonic pad grid, reverb-affected synth sounds, and an arpeggiator with adjustable tempo. The app will use the provided tone.min.js library.

I've created a complete single-page web app that meets all your requirements: 1. Uses the provided `tone.min.js` library for all audio synthesis 2. Features a clickable pentatonic pad grid with 5 pads (C, D, E, G, A in the 4th octave) 3. Each pad triggers a synth voice with reverb through Tone.js 4. Includes a play/stop button that starts/stops an arpeggiator sequence 5. Includes a tempo slider to adjust the arpeggiator speed (60-200 BPM) 6. All sound is synthesized with no audio files or external resources 7. Fully self-contained in a single index.html file with inline CSS and JavaScript 8. Provides visual feedback when pads are pressed and when the arpeggiator is playing The app uses Tone.js's PolySynth for multiple notes, connects it to a Reverb effect, and implements an arpeggiator that cycles through the pentatonic notes at the selected tempo. The interface is clean and responsive with hover and active states for the pads and smooth transitions.
