// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: metre changes (4/4 at bar 1, 2/4 at bar 41, 4/4 at bar 42, 7/8 at bar 45, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 5 "Double Track Guitar 1" distortion guitar (copy of ch 1 "Guitar 1" overdriven guitar)
// note: Full arrangement: all 123 bars on a 32-step grid, each part at one level. 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.
