// 135 bpm, 4/4, key A minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (3/4 at bar 1, 4/4 at bar 1, 3/4 at bar 2, 2/4 at bar 3, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: sustain pedal (CC 64) lengthens the held notes
// note: Full arrangement: all 112 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 Dis.

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