// note: sustain pedal (CC 64) lengthens the held notes
// note: duplicate parts dropped: ch 11 alto sax (copy of ch 9 alto sax, 0.146 beats late)
// note: Full arrangement: all 140 bars on a 24-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
