// 80 bpm, 3/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Transcription provider: pdmx. https://musescore.com/score/5887256; license: https://creativecommons.org/publicdomain/zero/1.0/
// note: Full arrangement: all 73 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 · "a, b" plays two voices at once.
// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
