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.
Here's a single self-contained index.html implementing your requirements: - Pentatonic pad grid (5 pads horizontally for pentatonic scale notes) - Clicking a pad triggers synth sound with reverb - Play/Stop button toggles an arpeggiator sequence which runs through the pads in sequence repeatedly - Adjustable tempo slider (BPM) tone.min.js is loaded externally via <script src="tone.min.js"></script> in the current directory I'll write the entire file now.

I wrote index.html with the following features: - 5 pentatonic pads labeled C4, D4, E4, G4, A4 in a horizontal grid - Click a pad to trigger a synth note with reverb - Play/Stop button starts/stops an arpeggiator cycling through the 5 pads sequentially - Tempo slider adjusts BPM for the arpeggiator (40-200 BPM) All synthesis is done via the Tone.js synth + reverb, no audio files used. The app is self-contained using tone.min.js loaded locally. You can open index.html in a modern browser and start playing! Let me know if you want me to enhance or customize it further.

EVALUATION
Static pentatonic pad grid with play button and tempo slider renders, but no visible reaction to any input tested.

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.
