// Concerto for 4 Harpsichords in A minor BWV 1065 — Johann Sebastian Bach after Antonio Vivaldi's op.3 no.10 RV 580
// 112 bpm, 6/8, key A minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: ch 1 "Violin I" named as a string part, played on violin (its harpsichord patch is not one); ch 4 "Violin II" named as a string part, played on violin (its harpsichord patch is not one)
// note: Transcription provider: pdmx. https://musescore.com/score/1536826; license: https://creativecommons.org/publicdomain/mark/1.0/
// note: Full arrangement: all 56 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
setcpm(112/3)

// 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.

// chords · violin · "Violin I"
