// Sonatine in A major Op.68 — Anton Diabelli
// 39 bpm, 2/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (1/8 at bar 1, 2/4 at bar 2, 3/8 at bar 45, 1/8 at bar 45, ...) are rendered on a constant 2/4 grid of one bar per cycle
// note: Transcription provider: pdmx. https://musescore.com/score/3826901; license: https://creativecommons.org/publicdomain/zero/1.0/
// note: Full arrangement: all 67 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(39/2)

// 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.
