// Generated by strudelify. One cycle = one bar.
// note: metre changes (4/4 at bar 1, 2/4 at bar 35, 4/4 at bar 35) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 13 piano (copy of ch 11 piano)
// note: Full arrangement: all 52 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
