**Defining App Functionality**

I'm now zeroing in on defining the core functionalities for the single-page web app. The features are outlined: a pentatonic pad grid will trigger synth sounds, a synth voice will have reverb, and there will be a play/stop button for an adjustable tempo arpeggiator. It will all be synthesized, no pre-recorded audio files.

The web app is now available in `index.html`. It includes a pentatonic pad grid that triggers a synth with reverb, and an arpeggiator that cycles through the notes. To run it, simply open `index.html` in any modern web browser. The app relies on the `tone.min.js` file located in the same directory.
