// 76 bpm, 2/4, key D# minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (2/4 at bar 6, 4/4 at bar 7, 2/4 at bar 13, 4/4 at bar 14, ...) are rendered on a constant 2/4 grid of one bar per cycle
// note: Full arrangement: all 194 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(76/2)

// Notation: c3@3 lasts 3 steps · ~ is a rest · [c3,e3] is a chord · [...]/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.
