// 160 bpm, 4/4, key G major. Source: midi.
// 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, 3/4 at bar 5, 4/4 at bar 6, 7/8 at bar 134, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 2 "Guitar 2" overdriven guitar (copy of ch 1 "Guitar 1" distortion guitar)
// note: Full arrangement: all 162 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.

// Notation: c3@3 lasts 3 steps · ~ is a rest · [c3,e3] is a chord · [...]/2 spreads a riff over 2 bars.
// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
