// 155 bpm, 4/4, key G major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: ch 6 "Guitar" named as a guitar, played on electric guitar clean (its piano patch is not one)
// note: duplicate parts dropped: ch 6 "Guitar" electric guitar clean (copy of ch 3 "Guitar" electric guitar muted)
// note: Full arrangement: all 147 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. 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.
// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
