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.

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.
I'll create a self-contained HTML file that includes the following: - A grid of clickable pads for the pentatonic scale. - A synth voice with reverb. - A play/stop button for an arpeggiator sequence with adjustable tempo. Here's the implementation of the web app in `index.html`: ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Pentatonic Pad Grid</title> <style> body { display: flex; flex-direction: column; align-items: center; font-family: Arial, sans-serif; background-color: #282c34; color: white; } .pad { width: 60px; height: 60px; margin: 5px; background-color: #61dafb; display: inline-block; border-radius: 10px; cursor: pointer; transition: background-color 0.3s; } .pad:hover { background-color: #21a1f1; } #controls { margin-top: 20px; } </style> </head> <body> <h1>Pentatonic Pad Grid</h1> <div id="grid"></div> <div id="controls"> <button id="playStopBtn">Play</button> <input type="range" id="tempoSlider" min="60" max="180" value="120" /> <label for="tempoSlider">Tempo: <span id="tempoValue">120</span> BPM</label> </div> <script src="tone.min.js"></script> <script> const synth = new Tone.Synth({ oscillator: { type: 'sine' }, envelope: { attack: 0.1, decay: 0.2, sustain: 0.9, release: 1 } }).toDestination(); const reverb = new Tone.Reverb(2).toDestination(); synth.connect(reverb); const notes = ['C4', 'D4', 'E4', 'G4', 'A4']; // Pentatonic scale notes const grid = document.getElementById('grid'); // Create the pad grid notes.forEach(note => { const pad = document.createElement('div'); pad.className = 'pad'; pad.innerText = note; pad.onclick = () => synth.triggerAttackRelease(note, "8n"); grid.appendChild(pad); }); let isPlaying = false; const loop = new Tone.Loop(time => { const note = notes[Math.floor(Math.random() * notes.length)]; synth.triggerAttackRelease(note, "8n", time); }, "8n"); document.getElementById('playStopBtn').onclick = () => { if (isPlaying) { Tone.Transport.stop(); loop.stop(); document.getElementById('playStopBtn').innerText = 'Play'; } else { Tone.Transport.bpm.value = document.getElementById('tempoSlider').value; // Set BPM Tone.Transport.start(); loop.start(0); document.getElementById('playStopBtn').innerText = 'Stop'; } isPlaying = !isPlaying; }; document.getElementById('tempoSlider').oninput = function() { document.getElementById('tempoValue').innerText = this.value; if (isPlaying) { Tone.Transport.bpm.value = this.value; } }; </script> </body> </html> ``` Now, I'll write this content into a file named `index.html`.

The `index.html` file has been successfully created with the pentatonic pad grid and arpeggiator functionality. You can now open this file in a web browser to use the app. Here’s a summary of what it includes: - A grid of clickable pads for the pentatonic scale. - A synth voice with reverb. - A play/stop button for the arpeggiator with an adjustable tempo. Let me know if you need any further modifications or assistance!
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Static pentatonic pad grid with play button and tempo slider, but no visible reaction to any input; unclear if audio works.
Vision grade · anthropic/claude-sonnet-5
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.
