// Orchestral Suite No.2 in B minor BWV 1067 — Johann Sebastion Bach
// 116 bpm, 2/4, key D major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (1/4 at bar 1, 2/4 at bar 2, 1/4 at bar 17, 2/4 at bar 18, ...) are rendered on a constant 2/4 grid of one bar per cycle
// note: ch 1 "Flute" named as a pipe, played on flute (its tremolo strings patch is not one); ch 2 "Violin I" named as a string part, played on violin (its harpsichord patch is not one)
// note: Transcription provider: pdmx. https://musescore.com/score/1060576; license: https://creativecommons.org/publicdomain/mark/1.0/
// note: Full arrangement: all 33 bars on a 16-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.
