// Octavia — Marcus Warner
// 88 bpm, 3/4, key F major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (1/4 at bar 1, 3/4 at bar 1) are rendered on a constant 3/4 grid of one bar per cycle
// note: ch 1 "Flute" named as a pipe, played on flute (its acoustic bass patch is not one); ch 3 "Horn in F" named as a brass, played on brass section (its violin patch is not one)
// note: Transcription provider: pdmx. https://musescore.com/score/5952568; license: https://creativecommons.org/publicdomain/zero/1.0/
// note: Full arrangement: all 144 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 · [...]/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.

// other · brass section · "Horn in F"
