// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: pitch bends are ignored
// note: sustain pedal (CC 64) lengthens the held notes
// note: duplicate parts dropped: ch 4 "tom mid 2  45     4" electric bass finger (copy of ch 3 "tom mid 2  45     3" acoustic bass); ch 7 "tom mid 2  45     7" electric guitar clean (copy of ch 8 "tom mid 2  45     8" electric guitar jazz)
// note: Full arrangement: all 64 bars on a 48-step grid, each part at one level. Source detail keeps the original performance.
