// Wachet auf — Bach Johann Sebastian
// 68 bpm, 4/4, key G major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 6 "STRINGS" string ensemble 1 (copy of ch 4 "A.PIANO 1" piano)
// note: Full arrangement: all 26 bars on a 48-step grid, each part at one level. Source detail keeps the original performance.
setcpm(68/4)

// Notation: c3@3 lasts 3 steps · ~ is a rest · [...]/2 spreads a riff over 2 bars.
// A part's distinct bars are riffs (A, B, C...) played in order, A@4 for four bars: edit a riff to change every repeat.
