Arpeggiator pad · minimax-m2.1
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 with: 1. A clickable pentatonic pad grid 2. Synth voice with reverb 3. Play/stop button for an arpeggiator sequence 4. Adjustable tempo I need to: 1. First check what's in the current directory 2. Use tone.min.js that's already there 3. Build everything in a single index.html file Let me first check what's in the current directory.

Good, tone.min.js is already present. Now I'll build a single-page web app with: 1. A pentatonic pad grid (clickable buttons that play notes) 2. Synth voice with reverb using Tone.js 3. Play/stop button for an arpeggiator 4. Adjustable tempo slider Let me create the index.html file with all the functionality.

I've created the index.html file. Let me verify it exists and check the structure is correct.

The file is created. Let me verify the HTML is well-formed by checking it.
Done! I've created a single-page web app with: **Features:** - **Pentatonic Pad Grid**: 21 colorful buttons spanning C4 to C8 (C D E G A scale - notes that always sound harmonious together) - **Synth Voice with Reverb**: Uses Tone.js PolySynth with triangle oscillator, ADSR envelope, and reverb effect - **Arpeggiator**: Play/Stop button runs an 8-note arpeggiator pattern (C4→E4→G4→A4→C5→A4→G4→E4) - **Adjustable Tempo**: Slider controls BPM from 60-200 - **Visual Feedback**: Pads light up when clicked or triggered by arpeggiator - **Keyboard Support**: Keys map to pads (z=s C4, x=E4, c=G4, v=A4, etc.) **Sound Design:** - Poly synth for pad clicks (plays multiple notes) - Separate sine wave synth for arpeggiator with longer reverb - Compressor for balanced output The file is fully self-contained with inline CSS and JavaScript, using the pre-loaded `tone.min.js` library. Open `index.html` in a browser to start making music!

EVALUATION
Pentatonic pad grid with play/tempo controls renders well but shows minimal visual response to click/drag/keys (only slight highlight in drag).

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.
