Arpeggiator pad · grok-4.6
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 using Tone.js that's already present in the current directory. Let me first check what's in the directory and understand the Tone.js library that's ava...
I'll inspect the workspace and Tone.js so I can build a self-contained pentatonic pad with arpeggiator.

I have tone.min.js available. I need to build a single-page web app in index.html that:

The user asked for a single-page web app with Tone.js. I've created it. Let me verify the file exists and is complete. The task is done.
`index.html` is a self-contained pentatonic pad app that loads local `tone.min.js` only. - **20 pads** — C minor or C major pentatonic across octaves 2–5 - **Click/hold** a pad to play a triangle `PolySynth` through a lowpass filter and hall reverb - **Play/Stop** runs a 16th-note arpeggiator (up, down, up/down, random) - **Tempo** slider, 50–180 BPM All sound is synthesized; no network or audio files.

EVALUATION
Pentatonic pad grid with play/tempo/scale controls renders; click highlights a pad, but no visual sound feedback confirmed and other inputs inert.

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.
