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.

The user wants me to create a single-page web app with a playable piano keyboard using Tone.js. Let me first check what's in the current directory and examine the tone.min.js file to understand its API.
{"command":"ls -la /tmp/ws/"}total 344 drwxr-sr-x. 2 node node 25 Aug 1 20:27 . drwxrwsrwx. 3 root node 16 Aug 1 20:27 .. -rw-r--r--. 1 node node 349169 Aug 1 20:27 tone.min.js

Good, tone.min.js is present. Now let me create a single-page web app with: 1. A visual piano keyboard 2. Mouse click support to play notes 3. Computer keyboard support (mapping keys to piano keys) 4. ADSR envelope for sound synthesis 5. Visual feedback when keys are pressed I'll use Tone.js's Synth or PolySynth with an ADSR envelope. Let me write the complete index.html file.

The file is created successfully. Let me provide a summary of what was built.
Created `index.html` - a fully self-contained piano keyboard app with: **Features:** - **Visual Piano Keyboard**: 25 keys (C3 to E5) with realistic white and black keys - **Mouse/Touch Control**: Click or tap any key to play - **Keyboard Mapping**: Computer keys map to piano notes (Z-M for lower octave, Q-T for upper) - **ADSR Envelope Controls**: Real-time sliders for Attack, Decay, Sustain, and Release - **Volume Control**: Adjustable master volume - **Visual Feedback**: Keys light up when pressed (pink for white keys, green for black keys) - **Polyphonic Sound**: Multiple notes can play simultaneously using Tone.PolySynth - **Reverb Effect**: Added spatial reverb for richer sound **Keyboard Layout:** ``` Lower Octave: Z X C V B N M , . / Upper Octave: Q W E R T Y U Black Keys: S D G H J L ; 2 3 4 6 7 ``` Open in a browser and click "Start Audio" to begin playing!

EVALUATION
Clean piano UI with ADSR sliders and keyboard mapping, but requires 'Start Audio' first; no visible key press feedback in captured frames.
Vision grade · anthropic/claude-sonnet-5
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.
