// 135 bpm, 4/4, key D major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 4 "Guitar" acoustic guitar nylon (copy of ch 2 "Organs" drawbar organ); ch 10 "Drums" piano (copy of ch 9 "Bass" acoustic bass)
// note: Full arrangement: all 100 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 · "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.
