Arpeggiator pad · qwen3-coder
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.

I'll create a single-page web app with a pentatonic pad grid and arpeggiator using Tone.js. Let me build this step by step. First, let me check what files are available in the current directory:
{"command":"ls -la"}total 344 drwxr-sr-x. 2 node node 25 Aug 1 19:40 . drwxrwsrwx. 3 root node 16 Aug 1 19:40 .. -rw-r--r--. 1 node node 349169 Aug 1 19:40 tone.min.js
Great! I can see that `tone.min.js` is available. Now I'll create a self-contained HTML file with all the necessary CSS and JavaScript for the pentatonic pad grid and arpeggiator.

I've created a complete single-page web app with a pentatonic pad grid and arpeggiator. The app includes: 1. A responsive grid of 10 pads representing notes from the C major pentatonic scale (C4, D4, E4, G4, A4, C5, D5, E5, G5, A5) 2. Visual feedback when pads are triggered 3. Play/Stop buttons to control the arpeggiator sequence 4. Adjustable tempo control (30-300 BPM) 5. Reverb effect on all sounds using Tone.Reverb 6. Mobile-responsive design 7. Visual instructions for users The app uses the Tone.js library (tone.min.js) for all audio synthesis and doesn't require any external resources. All code is contained in a single HTML file with inline CSS and JavaScript. To use the app: 1. Click individual pads to play notes 2. Click "Play Arpeggiator" to start a random sequence 3. Adjust the tempo using the input field 4. Click "Stop Arpeggiator" to stop the sequence The design features a modern dark theme with gradient accents and smooth animations for a polished user experience.

EVALUATION
Clean pentatonic pad grid with arpeggiator controls; click pads highlight, no keyboard interactivity as expected.

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.
