// Generated by strudelify. One cycle = one bar.
// note: ch 2 "Metalic Effects on Piano 1" named as a piano, played on piano (its synth bass 2 patch is not one)
// note: duplicate parts dropped: ch 7 "Guitar" acoustic guitar steel (copy of ch 6 "Guitar" acoustic guitar steel); ch 12 "Harmony" piccolo (copy of ch 11 "Melody" flute)
// note: Full arrangement: all 173 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
