// 116 bpm, 4/4, key C major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: metre changes (4/4 at bar 1, 2/4 at bar 13, 4/4 at bar 13, 2/4 at bar 28, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: sustain pedal (CC 64) lengthens the held notes
// note: Full arrangement: all 142 bars on a 32-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
