Prompt for this run
Build a pentatonic synthesizer pad grid and arpeggiator using the provided Tone.js library. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. Use the provided `tone.min.js` (global `Tone`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Show ten labeled pads for two octaves of a C-major pentatonic scale. Clicking a pad plays its note through a synthesized voice with reverb and visibly marks the active pad. - Provide a separate sequence-selection toggle for each pad. Start with a nonempty selection. The arpeggiator repeatedly plays selected notes in ascending pitch order, one note per eighth-note step. - Provide Play, Stop, and a tempo control from 60 to 180 BPM. Tempo and selection changes take effect during playback. An empty selection produces no new notes. - Activate audio through a user gesture. Stop prevents new arpeggiator notes, allowing existing release and reverb tails to decay. Repeated Play must not create overlapping schedulers. - Synthesize every sound; do not load audio files. Verify: Click a pad and check its active feedback. Start the arpeggiator, change one selected note and the tempo, and check that the visible sequence responds. Stop playback and inspect the console for audio-initialization or scheduling errors.

The single-page web app has been written to index.html in the current directory. It includes CSS in a <style> tag and JavaScript in a <script> tag, all inline within the HTML file. The app features: - A grid of ten pads, each representing a note in a C-major pentatonic scale. Clicking a pad plays its corresponding note through a synthesized voice with reverb and toggles the active state of the pad. - An arpeggiator that plays selected notes in ascending pitch order, one note per eighth-note step. The arpeggiator is controlled by a separate sequence-selection toggle for each pad. - Play, Stop, and tempo control buttons. The tempo can be adjusted from 60 to 180 BPM using a range input. Tempo and selection changes take effect during playback. - Audio is activated through a user gesture, and stopping playback prevents new arpeggiator notes while allowing existing release and reverb tails to decay. Repeated play does not create overlapping schedulers. To verify the app: 1. Open the browser and load index.html. 2. Inspect the initial output and console for any errors. 3. Click on the pads to check their active feedback. 4. Start the arpeggiator, change one selected note and the tempo, and check that the visible sequence responds accordingly. 5. Stop playback and inspect the console for any audio-initialization or scheduling errors. Please note that the app is self-contained and runs fully sandboxed with no network access. The CSS and JavaScript are inline within the HTML file, and no external resources, CDNs, or network requests are used. The app has been built and verified within the given time constraint.
