// 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 11, 4/4 at bar 12, 2/4 at bar 37, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: ch 2 "Guitar-1" named as a guitar, played on electric guitar clean (its vibraphone patch is not one); ch 3 "Guitar-2" named as a guitar, played on electric guitar clean (its glockenspiel patch is not one); ch 4 "Guitar-3" named as a guitar, played on electric guitar clean (its music box patch is not one); ch 5 "Guitar-4" named as a guitar, played on electric guitar clean (its tubular bells patch is not one)
// note: duplicate parts dropped: ch 11 "MiniMoog" lead 2 sawtooth (copy of ch 12 "MiniMoog*" synth bass 1)
// note: Full arrangement: all 95 bars on a 32-step grid, each part at one level. Source detail keeps the original performance.
// note: Guitar parts that double another keep only their own notes (fills, solos): Guitar-4.
