// 84 bpm, 4/4, key A major. Source: mcgill + midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (4/4 at bar 1, 2/4 at bar 20, 4/4 at bar 21, 2/4 at bar 27, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: Full arrangement: all 94 bars on a 48-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
// note: Guitar parts that double another keep only their own notes (fills, solos): guitar program 30.

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