// 96 bpm, 4/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: metre changes (4/4 at bar 1, 3/4 at bar 20, 2/4 at bar 20, 4/4 at bar 21, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: Full arrangement: all 105 bars on a 32-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 2 Double.
