// note: pitch bends are ignored
// note: duplicate parts dropped: ch 11 "Baritone Sax" baritone sax (copy of ch 8 "Distortion Guitar" distortion guitar)
// note: Full arrangement: all 100 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
// note: Guitar parts that double another keep only their own notes (fills, solos): Guitar harmonics.
