// 120 bpm, 4/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 6 synth bass 1 (copy of ch 2 electric bass finger)
// note: Full arrangement: all 71 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 part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
