The single-file web app `index.html` is now ready in `/tmp/ws/`. Here's what it includes: --- ### **Features** 1. **Pentatonic Pad Grid** - 5×5 grid of clickable pads, each playing a note from the C major pentatonic scale (C4–C6). - Click pads to toggle notes (green = active). Selected notes are used for the arpeggiator. 2. **Synth with Reverb** - Polyphonic sine-wave synth with a simple envelope. - Reverb effect (2.5s decay, 30% wet mix). 3. **Arpeggiator** - Play/Stop button to toggle an arpeggiator sequence using selected notes. - Adjustable tempo (60–240 BPM) via slider. 4. **Fully Self-Contained** - No external resources (CSS/JS inline, no CDNs). - Uses `tone.min.js` (pre-provided) for audio synthesis. --- ### **How to Use** 1. Open `index.html` in a browser. 2. Click pads to select notes (e.g., C4, D4, E4, G4, A4). 3. Click **Play Arpeggiator** to start the sequence. 4. Adjust tempo with the slider. 5. Click **Stop Arpeggiator** to halt playback.
