// Generated by strudelify. One cycle = one bar.
// note: metre changes (4/4 at bar 1, 3/4 at bar 33, 4/4 at bar 33, 3/4 at bar 62, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: ch 3 "Lead Gtr" named as a guitar, played on overdriven guitar (its lead 8 bass lead patch is not one)
// note: Full arrangement: all 216 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
