// 120 bpm, 4/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 11 "Acoustic Guitar II" acoustic guitar steel (copy of ch 3 "Acoustic Guitar I" acoustic guitar steel, 0.083 beats late); ch 15 "Acoustic Guitar IV" acoustic guitar nylon (copy of ch 14 "Acoustic Guitar III" acoustic guitar nylon, 0.083 beats late)
// note: Full arrangement: all 115 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
// note: Guitar parts that double another keep only their own notes (fills, solos): Electric Guitar II, Electric Guitar III.

// 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.
