// RACHMANINOFF Suite No. 1 or Fantasie-tableaux for two pianos IV. Paques - Easter — Sergei Rachmaninoff
// 98 bpm, 4/4, key Bb 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 (1/8 at bar 1, 4/4 at bar 2) are rendered on a constant 4/4 grid of one bar per cycle
// note: Transcription provider: pdmx. https://musescore.com/score/2085246; license: https://creativecommons.org/publicdomain/zero/1.0/
// note: Full arrangement: all 58 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(98/4)

// 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.
