// 74 bpm, 2/4, key C minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (4/4 at bar 1, 2/4 at bar 26, 4/4 at bar 27, 2/4 at bar 45) are rendered on a constant 2/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 11 "CLEAN GTR" electric guitar clean (copy of ch 9 "STEEL GTR" acoustic guitar steel)
// note: Full arrangement: all 96 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
