// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 13 "Doubled Overdrive Guitar" overdriven guitar (copy of ch 3 "Heavy Guitar" distortion guitar)
// note: Full arrangement: all 95 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.
