Arpeggiator pad · llama-4-scout
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 will read the tone.min.js file to ensure it's available for use in our script. ```bash ```
