Arpeggiator pad · glm-5.2
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.

Let me build a pentatonic pad grid with synth, reverb, and arpeggiator using Tone.js. Let me first verify tone.min.js exists.

Let me build the index.html file. I'll create a pentatonic pad grid with synths, reverb, and an arpeggiator.

Done. I built `/workspace/index.html` — a self-contained pentatonic pad grid app using the pre-provided `tone.min.js` (global `Tone`), with no external resources or audio files. **What it does:** - **5×8 pad grid** laid out on a pentatonic scale (major or minor, switchable). Top rows = higher pitches. Click any pad to toggle it on and trigger the synth voice immediately. - **Synth voice**: `Tone.PolySynth` with a fatsawtooth oscillator + pluck-ish envelope routed through a **`Tone.Reverb`** (decay ~4.5s) into a master gain → destination. - **Reverb wet** is adjustable (0–100%) in real time. - **Play/Stop button** starts a `Tone.Loop` arpeggiator on `Tone.Transport`. It steps column-by-column through all active pads (rebuilding the sequence each cycle so toggles take effect live) and triggers each at the correct Transport time. - **Tempo slider** (60–180 BPM) updates `Tone.Transport.bpm`. - **Arp Rate** slider picks 1/16, 1/8, 1/8., 1/4, 1/2 note intervals. - **Extras**: Clear button, Random button (fills ~25% of pads), drag-to-paint across pads, `Space` key toggles playback, scale selector rebuilds the grid, and visual hit-flashes on triggered pads. All sound is synthesized in-browser via Tone.js; the only loaded file is `tone.min.js`.

EVALUATION
Pentatonic pad grid with play/stop, tempo/reverb/arp controls; drag selects pads, Enter/Space starts arpeggiator playback.

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.
