Fix drum classification and tighten piano rhythm grid

Real drum samples from LinnDrum CDN, tighter rhythm and fewer notes

Sample-based drum kit and tighter rhythm snapping

Tighten rhythm snapping and fix drum sync

LH anchors on melody (top note), enforce span on concurrent notes too

Enforce hand span limit — no chord wider than an octave per hand

Merge repeated same-pitch notes into sustains, increase drum detection sensitivity

Add rhythm consolidation step to discipline note onsets

Remove hand outlier harmonics, rewrite drum transcription with multi-band detection

Use solo piano optimizer for full-song melodic stem, reduce LH bass notes

Improve transcription fidelity: trailing notes, sustain pedal, complexity tuning

Enhance spurious onset filter for higher precision

Improve register balance: CQT-check bass, relax upper threshold

Fix tempo doubling and reduce harmonic ghost over-removal
