// 131 bpm, 4/4, key A minor. 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, 2/4 at bar 12, 4/4 at bar 13, 2/4 at bar 40, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 8 fretless bass (copy of ch 7 acoustic bass)
// note: Full arrangement: all 136 bars on a 24-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 25.
setcpm(131/4)

// Notation: c3@3 lasts 3 steps · ~ is a rest · [c3,e3] is a chord · "a, b" plays two voices at once · [...]/2 spreads a riff over 2 bars.
// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
