// 180 bpm, 3/4, key Eb major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Transcription provider: pdmx. https://musescore.com/score/5377209; license: https://creativecommons.org/publicdomain/zero/1.0/
// note: Full arrangement: all 219 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
setcpm(180/3)

// Notation: c3@3 lasts 3 steps · ~ is a rest.
// A part's distinct bars are riffs (A, B, C...) played in order, A@4 for four bars: edit a riff to change every repeat.
