// 70 bpm, 4/4, key D major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (4/4 at bar 1, 2/4 at bar 11, 4/4 at bar 12, 2/4 at bar 17, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: duplicate parts dropped: ch 3 "B♭ Trumpet" trumpet (copy of ch 1 "B♭ Trumpet" trumpet); ch 6 "Mellophone" french horn (copy of ch 5 "Horn in F" french horn); ch 8 "Trombone" trombone (copy of ch 7 "Trombone" trombone); ch 9 "Trombone" trombone (copy of ch 7 "Trombone" trombone)

// Notation: c3@3 lasts 3 steps · ~ is a rest · "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.
