// 87 bpm, 6/8, key D major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: pitch bends are ignored
// note: Full arrangement: all 78 bars on a 24-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
