Arpeggiator pad · llama-3.1-70b-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 provided code uses the Tone.js library to create a pentatonic pad grid that triggers a synth voice with reverb when clicked, and a play/stop button that runs an arpeggiator sequence at an adjustable tempo. The code first creates a pentatonic scale array and initializes the Tone.js synthesizer, reverb, and arpeggiator. It then creates a grid of pads and adds an event listener to each pad to trigger a note when clicked. The code also creates a tempo input slider and adds an event listener to update the arpeggiator interval when the slider value changes. Finally, it adds an event listener to the play/stop button to start and stop the arpeggiator. Note that this code assumes that the Tone.js library is already loaded in the HTML file.

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.
