// 96 bpm, 12/8, key G 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 (3/8 at bar 1, 12/8 at bar 2) are rendered on a constant 12/8 grid of one bar per cycle
// note: Full arrangement: all 50 bars on a 24-step grid, each part at one level. Source detail keeps the original performance.

// Notation: c3@3 lasts 3 steps · ~ is a rest · [c3,e3] is a chord · [...]/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.
