The user wants me to create a single-page web app using the pre-provided tone.min.js library. I need to: 1. Create a clickable pentatonic pad grid that triggers a synth voice with reverb 2. Add a play/stop button that runs an arpeggiator sequence at adjustable tempo 3. All sound should be synthesized using Tone.js, no audio files 4. Everything in one self-contained index.html file Let me first check if tone.min.js exists in the current directory.

I need to create a self-contained index.html file that uses the pre-existing tone.min.js library. The app should have: 1. A clickable pentatonic pad grid that triggers a synth voice with reverb 2. A play/stop button that runs an arpeggiator sequence at an adjustable tempo 3. All sound synthesized using Tone.js, no audio files Let me create a pentatonic scale (5 notes per octave) grid, add a synth with reverb, and create an arpeggiator feature.

Done! I've created `/tmp/ws/index.html` - a self-contained pentatonic pad web app with: **Features:** - **5-pad pentatonic grid** (C minor pentatonic: C, D♭, E♭, G, A♭) - **Clickable pads** that trigger a synthesized synth voice with reverb - **Play/Stop button** that runs an arpeggiator sequence (bounces up/down through the scale) - **Adjustable tempo** slider (60-200 BPM) with live display - **Octave selector** (3, 4, 5) to change pitch range - **Visual feedback** - pads light up when played or during arpeggiation **Sound Design:** - Triangle wave oscillator for smooth tones - ADSR envelope (fast attack, medium decay/sustain, long release) - Reverb effect with 2.5s decay for ambient space - PolySynth for overlapping notes **UI:** - Dark gradient theme with glowing accents - Responsive grid layout - Smooth hover/active animations - Clear instructions panel Open `index.html` in a browser and click anywhere to initialize the audio context, then start playing!

Static pentatonic pad UI with tempo slider and play button; no visible pixel changes to any input, audio not verifiable.

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.
