// Nobody Home — Pink Floyd
// 99 bpm, 4/4, key C major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: duplicate parts dropped: ch 7 "strings2" synth strings 1 (copy of ch 6 "strings1" string ensemble 1)
// note: Full arrangement: all 85 bars on a 24-step grid, each part at one level. Source detail keeps the original performance.
setcpm(99/4)

// 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.
