// Somebody's Watching Me — Rockwell
// 122 bpm, 4/4, key C# minor. Source: mcgill + midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 9 "syn bass" synth bass 1 (copy of ch 2 "bass" fretless bass)
// note: Full arrangement: all 98 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(122/4)

// 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.
