// 135 bpm, 4/4, key A 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; ghost notes are separate "_soft" parts. Source detail keeps the original performance.

// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
