// 160 bpm, 4/4, key G major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (2/4 at bar 1, 4/4 at bar 2, 2/4 at bar 5, 4/4 at bar 5, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 7 "Guitar 1+" distortion guitar (copy of ch 1 "Guitar 1" overdriven guitar); ch 5 "Keyboard +" pad sweep (copy of ch 4 "Keyboard" pad poly)
// note: Full arrangement: all 207 bars on a 24-step grid, each part at one level. Source detail keeps the original performance.

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