// Generated by strudelify. One cycle = one bar.
// note: metre changes (4/4 at bar 1, 3/4 at bar 6, 5/4 at bar 6, 3/4 at bar 8, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: Full arrangement: all 63 bars on a 24-step grid, each part at one level. Source detail keeps the original performance.
