// 125 bpm, 4/4, key E minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Full arrangement: all 115 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): Dexter.
setcpm(125/4)

// Notation: c3@3 lasts 3 steps · ~ is a rest · [c3,e3] is a chord.
// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
