// Venus Valse — Herbert Lincoln Clarke
// 228 bpm, 3/4, key G 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 (3/4 at bar 1, 14/4 at bar 15, 3/4 at bar 23) are rendered on a constant 3/4 grid of one bar per cycle
// note: Transcription provider: pdmx. https://musescore.com/score/6242202; license: https://creativecommons.org/publicdomain/zero/1.0/
// note: Full arrangement: all 188 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. 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.
