// 126 bpm, 6/4, key C# minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (6/4 at bar 1, 4/4 at bar 9, 6/4 at bar 17, 4/4 at bar 25, ...) are rendered on a constant 6/4 grid of one bar per cycle
// note: duplicate parts dropped: ch 3 "Cantrell - Rhythm 2" distortion guitar (copy of ch 2 "Cantrell - Rhythm 1" distortion guitar)
// note: Full arrangement: all 66 bars on a 24-step grid, each part at one level. Source detail keeps the original performance.
setcpm(126/6)

// 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.
