Backend Enhancements: - Add ParsedMIDIInfo with track analysis and quality issues - New /api/midi/parse endpoint for MIDI metadata extraction - Enhanced MIDIService with parseMIDI method MIDI Preview Player: - Complete MIDIPlayer class with polyphonic playback - Basic oscillator mapping (bass=square, mid=triangle, high=sine) - Lookahead scheduling with proper cleanup - Automatic stopping when MIDI ends New UI Flow: 1. Search → Results table with metadata 2. Select MIDI → Shows parsed info (duration, tracks, tempo) 3. Dual transport: Preview Original vs Generate Motif 4. Try Next Result button for easy A/B testing Search Results Table: - Title, source, confidence bar, duration, track count - Quality issues display (short duration, few notes, etc.) - Auto-select best result, manual selection available - Visual confidence bars and issue warnings This makes the project feel "real" - you can now: - See exactly what MIDI was found - Verify it's the right song via preview - Compare original vs procedural synthesis - Easily try different results 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
