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.
thinking
The user wants me to build a playable piano keyboard web app that: 1. Uses Tone.js (already provided as tone.min.js) 2. Is controlled by mouse clicks and computer keyboard 3. Synthesizes notes with an ADSR envelope 4. Has visual key feedback Let me create a self-contained index.html file with: - CSS styling for piano keys (white and black) - JavaScript using Tone.js for synthesis with ADSR - Mouse click handlers - Keyboard event handlers - Visual feedback when keys are pressed I'll need to: 1. Load tone.min.js via script tag 2. Create a piano keyboard layout (at least 1-2 octaves) 3. Map computer keys to piano notes 4. Create a synthesizer with ADSR envelope 5. Add visual feedback (change color/opacity when pressed) Let me build this.

I've created a comprehensive piano keyboard application. Let me verify it's in place and working.
I've created a fully-featured piano keyboard application in `index.html`. Here's what it includes: ## Features **Playable Keys:** - 13 keys spanning one octave plus one note (C4 to C5) - 8 white keys and 5 black keys (sharps/flats) - Visual feedback with red highlight when keys are pressed - 3D key press animation effect **Input Methods:** - **Mouse/Touch:** Click or tap any key to play - **Keyboard:** Keys A, W, S, E, D, F, T, G, Y, H, U, J, K map to the piano notes **ADSR Envelope Controls:** - **Attack:** 0.01s - 2s (how quickly sound reaches full volume) - **Decay:** 0.01s - 2s (time to fall to sustain level) - **Sustain:** 0 - 1 (volume level held while key is pressed) - **Release:** 0.01s - 3s (fade-out time after key release) **Waveform Selection:** - Sine (smooth, pure tone) - Triangle (mild, hollow) - Square (buzzy, retro) - Sawtooth (bright, edgy) **Visual Design:** - Dark gradient background with glowing accents - Realistic 3D piano key styling with shadows - Active key highlighting in pink/red - Control panel with sliders for real-time adjustments The app uses Tone.js (loaded from the provided `tone.min.js`) to create a polyphonic synthesizer with configurable ADSR envelope. Audio starts after clicking the "Click to Start" button (required by browsers for audio context activation).
