// 108 bpm, 4/4, key B minor. Source: mcgill + 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, 2/4 at bar 8, 4/4 at bar 9, 2/4 at bar 16, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 3 "Acoustic Guitar (Guitar 1)" acoustic guitar steel (copy of ch 2 "Electric Guitar (Guitar 2)" electric guitar clean)
// note: Full arrangement: all 181 bars on a 24-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 · "a, b" plays two voices at once · [...]/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.
