// Generated by strudelify. One cycle = one bar.
// note: metre changes (1/4 at bar 1, 4/4 at bar 2, 2/4 at bar 15, 4/4 at bar 15, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: Full arrangement: all 52 bars on a 24-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
