The user wants me to create 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.min.js (no external audio files) Let me first check what's in the current directory and look at the tone.min.js file to understand its API.

Good, tone.min.js is present. Now let me create a single-page web app with: 1. A pentatonic pad grid (I'll use C major pentatonic or similar) 2. Synth voice with reverb 3. Play/stop button for arpeggiator 4. Adjustable tempo slider Let me build this now.

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.
