**Planning audio setup** I need to create and polish the audio setup. Ensuring tone compatibility is key, so using something like PolySynth from Tone makes sense. I should consider the ADSR controls, octave settings, and how I want to map the keyboard across two octaves. This involves determining positions for the keys as well as mouse pointer events. I should also initialize audio correctly and check the Tone version to ensure everything works seamlessly.

**Developing a polished single** I'm getting ready to build a polished single, but I'm thinking I might need to test in a browser that's currently unavailable. I need to work on writing and synthesizing ADSR controls visually. I'll include precise key mappings for two octaves, C4 to B5. It looks like I need a unique set of mappings, possibly including conventional chromatic notes but ensuring there's no conflict. I'll also have to consider how to implement mouse glissando and pointer events for interaction. Lastly, I want to determine the version of the Tone.js API.

RUN
EVALUATION
Piano UI renders nicely but keys never visually depress or highlight for any input; JS NaN error suggests broken interactivity.

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.
