// Goodnight Saigon — Billy Joel
// 68 bpm, 4/4, key C major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: ch 3 "Bass" named as a bass, played on electric bass finger (its synth brass 2 patch is not one)
// note: sustain pedal (CC 64) lengthens the held notes
// note: duplicate parts dropped: ch 3 "Bass" electric bass finger (copy of ch 4 "Bass 2" fretless bass)
// note: Full arrangement: all 97 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
setcpm(68/4)

// 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.
