// Sarabande — Bach Johann Sebastian
// 75 bpm, 3/4, key A minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: sustain pedal (CC 64) lengthens the held notes
// note: duplicate parts dropped: ch 6 "STRINGS" string ensemble 1 (copy of ch 4 "A.PIANO 1" piano)
// note: Full arrangement: all 56 bars on a 24-step grid, each part at one level. Source detail keeps the original performance.
setcpm(75/3)

// 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.
