// Piano Concerto No.1 Op.23 — Peter Tchaikovsky
// 60 bpm, 6/8, key Db major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: sustain pedal (CC 64) lengthens the held notes
// note: Transcription provider: pdmx. https://musescore.com/score/5317610; license: https://creativecommons.org/publicdomain/zero/1.0/
// note: Full arrangement: all 123 bars on a 48-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
setcpm(60/3)

// 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.
