Fix piano roll quality, drum sounds, add original audio playback, fix speed
Ewan +1: Claude Opus 4.6- Add playability limits to full-song optimizer (limit_concurrent_notes, limit_total_concurrent, remove_harmonic_ghosts) — reduces note count to physically playable levels - Fix drum hi-hat not audible: increase MetalSynth volume -12 -> -4dB, extend trigger duration 32n -> 16n, boost crash/ride volumes too - Add original audio playback: new /api/jobs/{id}/audio endpoint serves uploaded file back, HTML Audio element synced to Transport with toggle button + volume slider in Controls - Fix speed scaler: preserve playbackRate via tempoRef across scheduleNotes reschedules (transport.stop() was losing the rate) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>b5c16f8
