// 86 bpm, 4/4, key D# major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: pitch bends are ignored
// note: ch 8 "GUITAR" named as a guitar, played on electric guitar clean (its music box patch is not one)
// note: duplicate parts dropped: ch 11 "CANTO" string ensemble 2 (copy of ch 9 "CANTO" piano)
// note: Full arrangement: all 74 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.
