- Multi-stage conversion progress tracking
- AI-based difficulty analysis (easy/medium/hard)
- Color-coded note visualization
- Real-time MIDI playback with difficulty indicators
- Comprehensive statistics (tempo, intervals, hand span)
- Visual difficulty distribution bars
User Flow:
1. Enter YouTube URL
2. View conversion progress (download → analyze → convert)
3. See difficulty analysis with colored notes
4. Practice with MIDI player
Integration:
- Added "YouTube → Tutorial" to main navigation
- Seamless routing between Dashboard and Score Following
Tech Stack:
- React + TypeScript
- Tone.js for MIDI playback
- @tonejs/midi for MIDI parsing
- CSS with gradient themes matching app design
Code Quality:
- Fixed ESLint warnings (no nested ternaries)
- Improved accessibility (keyboard navigation)
- Escaped HTML entities in JSX
Note: Current implementation uses placeholder conversion.
Production deployment requires backend API with:
- Audio extraction from YouTube
- AI pitch detection (e.g., Spotify Basic Pitch)
- MIDI file generation
