Arpeggiator pad · ministral-3b-2512

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.

It seems the `tone.min.js` file is a minified version without explicit imports, but Tone.js is a global library. Let's proceed by assuming Tone.js is available globally. Here's the plan for the single-page app: 1. **Pentatonic Pad Grid**: A 5-note grid where each note triggers a synth voice with reverb. 2. **Arpeggiator**: A play/stop button to run an arpeggiator sequence at an adjustable tempo. 3. **Sound Synthesis**: Use Tone.js to synthesize sound without external files. Here's the `index.html` file:

The `index.html` file has been created. Here's a breakdown of what it does: 1. **Pentatonic Pad Grid**: - A 5-note grid (C major pentatonic) where each note triggers a synth voice with reverb. - Each pad is visually distinct and labeled with its note number. 2. **Arpeggiator Controls**: - A play/stop button to toggle the arpeggiator. - A tempo slider to adjust the tempo (BPM) of the arpeggiator. 3. **Sound Synthesis**: - Uses Tone.js to synthesize sound for each note. - Each synth voice has reverb and overdrive for a richer sound. ### Features: - **Dynamic Pads**: Each pad triggers a synth voice with reverb. - **Arpeggiator**: Plays the pentatonic notes in sequence at the set tempo. - **Adjustable Tempo**: Change the tempo using the slider. ### How to Use: - Click any pad to play the corresponding note. - Click the "Play Arpeggiator" button to start the sequence. - Adjust the slider to change the tempo.

EVALUATION

★★★★★ 1/5 broken

Pentatonic pad grid is missing entirely; only a play button and tempo slider render, likely due to a JS error.
