I'll build a playable piano keyboard with Tone.js, ADSR envelope, and visual key feedback. Let me first check what's available in the current directory.

Great, tone.min.js is present. Now I'll create the complete piano keyboard application with all requested features.

The playable piano keyboard is complete! Here's what I've built: ## Features Implemented: 1. **Playable Piano Keyboard** - 9 white keys (C to C across 2 octaves) and 6 black keys (sharps) arranged in proper piano layout 2. **Mouse Control** - Click any key to play, with visual active-state feedback 3. **Computer Keyboard Control** - - White keys: A S D F G H J K L (C to C) - Black keys: W E T Y U O (C# to C#) 4. **ADSR Envelope** - Customizable attack, decay, sustain, release on all synth voices 5. **Visual Key Feedback** - Keys light up when pressed (blue for white keys, orange for black keys) 6. **Multiple Instruments**: - PolySynth (default) - FM Synth - AM Synth - DuoSynth - Membrane - Pluck 7. **Waveform Selection** - Sine, Triangle, Sawtooth, Square 8. **Effects** - Volume control and Reverb toggle 9. **Multi-note Display** - Shows currently active notes 10. **Audio Context** - Proper Tone.js initialization (requires user interaction) The design uses a dark gradient theme with a realistic piano UI, glass-morphism controls, and smooth animations. All code is self-contained in a single `index.html` file with inline CSS and JavaScript, loading the pre-provided `tone.min.js` library.
