// Summer Night City — ABBA
// 132 bpm, 4/4, key D minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 8 "Fretless Bass" fretless bass (copy of ch 1 "Synth Bass 1" synth bass 1)
// note: Full arrangement: all 122 bars on a 24-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
// note: The whole transcription plays 27 ms ahead of the beat; the grid follows it, so its parts stay together.
setcpm(132/4)

// Notation: c3@3 lasts 3 steps · ~ is a rest · [c3,e3] is a chord · [...]/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.
