// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: metre changes (2/4 at bar 1, 4/4 at bar 2) are rendered on a constant 4/4 grid of one bar per cycle
// note: Full arrangement: all 79 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
