Using the pre-provided tone.min.js (global Tone), build a playable piano keyboard controlled by mouse and computer keys that synthesizes notes with an ADSR envelope and visual key feedback.
I'll create a single-page web app with a playable piano keyboard that uses Tone.js for sound synthesis with ADSR envelope and visual feedback.

I've created a complete piano keyboard web application in a single index.html file. The app includes: 1. A visual piano keyboard with white and black keys 2. Mouse interaction - click and hold to play notes, release to stop 3. Keyboard support - use computer keys (A,S,D,F,G,H,J,K,L for white keys, W,E,T,Y,U,O for black keys) 4. Tone.js synthesizer with ADSR envelope for realistic sound 5. Controls to adjust Attack, Decay, Sustain, and Release parameters 6. Visual feedback - keys change color when pressed 7. No external resources - everything is self-contained in one file The application is ready to use. Just open the index.html file in a web browser to play the piano keyboard.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Piano keyboard with ADSR sliders responds to clicks/drags with key highlighting; arrow/wasd keys don't trigger additional visible changes.

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.
