// Generated by strudelify. One cycle = one bar.
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 5 "E.PIANO 2" epiano2 (copy of ch 4 "MELODY" acoustic guitar nylon); ch 9 "TROMBONE" trombone (copy of ch 8 "BRASS 1" brass section)
// note: Full arrangement: all 154 bars on a 24-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 · [...]/2 spreads a riff over 2 bars.
// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
