// 140 bpm, 4/4, key A minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: ch 8 "Special Guitar" named as a guitar, played on electric guitar clean (its marimba patch is not one)
// note: duplicate parts dropped: ch 1 "Acoustic Guitar (steel)" acoustic guitar nylon (copy of ch 2 "Ac Guitar (nylon)" acoustic guitar nylon)
// note: Full arrangement: all 217 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
// note: Guitar parts that double another keep only their own notes (fills, solos): El Guitar (Clean).
setcpm(140/4)

// 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.
