// Generated by strudelify. One cycle = one bar.
// note: pitch bends are ignored
// note: ch 8 "refrain strings" named as a string part, played on string ensemble 1 (its accordion patch is not one)
// note: Full arrangement: all 159 bars on a 32-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.
