// 130 bpm, 4/4, key G minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 6 "SWEEP PAD" pad sweep (copy of ch 4 "SLOWSTRIN" string ensemble 2)
// note: Full arrangement: all 99 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.
// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
