// note: metre changes (3/4 at bar 1, 1/8 at bar 26, 4/4 at bar 26, 2/4 at bar 49, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored

// note: Full arrangement: all 104 bars on a 32-step grid, each part at one level. Source detail keeps the original performance.
