// Generated by strudelify. One cycle = one bar.
// note: metre changes (1/8 at bar 1, 4/4 at bar 2) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: Full arrangement: all 168 bars on a 16-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.

// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
