// 109 bpm, 4/4, key C major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: ch 7 "wet synth bass" named as a bass, played on synth bass 1 (its distortion guitar patch is not one); ch 8 "flat synth bass" named as a bass, played on synth bass 1 (its distortion guitar patch is not one); ch 5 "fretless bass" named as a bass, played on fretless bass (its bassoon patch is not one)
// note: duplicate parts dropped: ch 5 "fretless bass" fretless bass (copy of ch 7 "wet synth bass" synth bass 1)
// note: Full arrangement: all 128 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.

// 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, A@4 for four bars: edit a riff to change every repeat.
