// 120 bpm, 4/4, key Bb major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (4/4 at bar 1, 3/4 at bar 50, 4/4 at bar 50, 2/4 at bar 51, ...) are rendered on a constant 4/4 grid of one bar per cycle

// note: Full arrangement: all 91 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.

// 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.
