Using the pre-provided tone.min.js (global Tone), build a clickable pentatonic pad grid that triggers a synth voice with reverb, plus a play/stop button that runs an arpeggiator sequence at an adjustable tempo. All sound synthesized, no audio files.

The user wants me to build a single-page web app with: 1. A clickable pentatonic pad grid that triggers a synth voice with reverb 2. A play/stop button that runs an arpeggiator sequence at adjustable tempo 3. All sound synthesized (no audio files) 4. Use tone.min.js which is already present in the current directory Let me first check if tone.min.js exists in the current directory, then create the index.html file with all the functionality. I'll need to: 1. Create a pentatonic scale (e.g., C major pentatonic: C, D, E, G, A) 2. Build a grid of pads that trigger notes with a synth + reverb effect 3. Add a play/stop button for an arpeggiator 4. Add tempo control 5. Make everything self-contained in one HTML file Let me write this comprehensive music app.

Good, tone.min.js is present. Now I'll create the index.html file with: 1. Pentatonic pad grid (5x4 or similar layout) 2. Synth voice with reverb using Tone.js 3. Play/stop button for arpeggiator 4. Tempo control slider 5. All CSS and JS inline Let me write a comprehensive music app.

The file has been created successfully. Let me summarize what I built for the user.
Done! Created `/tmp/ws/index.html` with: **Features:** - **16-pad pentatonic grid** (C Major Pentatonic across 4 octaves) - click/tap pads to trigger notes - **Polyphonic synth voice** with triangle wave, ADSR envelope - **Effects chain**: Reverb → Lowpass Filter → Feedback Delay - **Play/Stop button** - starts a dynamic arpeggiator with 8 different patterns (ascending, descending, skip patterns, fifth jumps) - **Tempo slider** - adjustable from 60-240 BPM with live display - **Keyboard shortcut** - Space bar toggles play/stop - **Visual feedback** - pads light up when triggered by both clicking and arpeggiator **All synthesized** using Tone.js - no audio files or external resources required. Just open `index.html` in a browser and click PLAY to start.

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.
