Arpeggiator pad · qwen-2.5-72b-instruct
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 single-page web app has been successfully created and written to `index.html` in the current directory. The app includes a pentatonic pad grid that triggers a synth voice with reverb, and a play/stop button that runs an arpeggiator sequence at an adjustable tempo. You can open `index.html` in a web browser to test the app. Here is the content of the file for reference: ```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; justify-content: center; height: 100vh; margin: 0; background: #282c34; color: white; font-family: Arial, sans-serif; } .pad { width: 100px; height: 100px; margin: 5px; background: #3e8e41; border-radius: 10px; display: flex; align-items: center; justify-content: center; cursor: pointer; transition: background 0.2s; } .pad:hover { background: #4caf50; } .controls { margin-top: 20px; } .tempo-input { margin-top: 10px; } .arpeggiator-btn { margin-top: 10px; padding: 10px 20px; background: #757575; color: white; border: none; border-radius: 5px; cursor: pointer; transition: background 0.2s; } .arpeggiator-btn:hover { background: #5a5a5a; } </style> </head> <body> <h1>Pentatonic Pad Grid</h1> <div class="pad-grid"> <div class="pad" data-note="C4"></div> <div class="pad" data-note="D4"></div> <div class="pad" data-note="E4"></div> <div class="pad" data-note="G4"></div> <div class="pad" data-note="A4"></div> <div class="pad" data-note="C5"></div> <div class="pad" data-note="D5"></div> <div class="pad" data-note="E5"></div> <div class="pad" data-note="G5"></div> <div class="pad" data-note="A5"></div> </div> <div class="controls"> <span>Tempo:</span> <input type="range" class="tempo-input" min="60" max="240" value="120"> <button class="arpeggiator-btn" id="arpeggiator-btn">Play Arpeggiator</button> </div> <script src="tone.min.js"></script> <script> const pads = document.querySelectorAll('.pad'); const tempoInput = document.querySelector('.tempo-input'); const arpeggiatorBtn = document.querySelector('#arpeggiator-btn'); let arpeggiator; let isPlaying = false; // Initialize the synth with reverb const synth = new Tone.Synth().toDestination(); const reverb = new Tone.Reverb(3).toDestination(); synth.chain(reverb); // Play a note when a pad is clicked pads.forEach(pad => { pad.addEventListener('click', () => { const note = pad.getAttribute('data-note'); synth.triggerAttackRelease(note, '8n'); }); }); // Initialize the arpeggiator const sequence = ['C4', 'E4', 'G4', 'A4', 'C5', 'E5', 'G5', 'A5']; arpeggiator = new Tone.Sequence((time, note) => { synth.triggerAttackRelease(sequence[note], '8n', time); }, sequence, '4n'); // Play/stop the arpeggiator arpeggiatorBtn.addEventListener('click', () => { if (isPlaying) { arpeggiator.stop(); arpeggiatorBtn.textContent = 'Play Arpeggiator'; isPlaying = false; } else { arpeggiator.start('0'); arpeggiator.set({ subdivisions: '16n' }); arpeggiatorBtn.textContent = 'Stop Arpeggiator'; isPlaying = true; } }); // Update the tempo of the arpeggiator tempoInput.addEventListener('input', () => { Tone.Transport.bpm.value = tempoInput.value; }); </script> </body> </html> ``` Enjoy the app!

EVALUATION
Only two narrow columns of pad tiles visible with tempo slider and play button; layout appears broken/cut off, only a few tiles highlight on interaction.
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.
