// note: duplicate parts dropped: ch 3 "chords" cello (copy of ch 2 "chords" synth bass 2)
// note: Full arrangement: all 83 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.

// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
