// 118 bpm, 4/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: duplicate parts dropped: ch 9 steel drums (copy of ch 4 music box); ch 8 synth strings 1 (copy of ch 7 synth strings 2)
// note: Full arrangement: all 117 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
