// note: pitch bends are ignored
// note: ch 1 "BASS" named as a bass, played on electric bass finger (its pad new age patch is not one); ch 2 "HIGH STRINGS" named as a string part, played on string ensemble 1 (its acoustic bass patch is not one); ch 6 "LOW STRINGS" named as a string part, played on string ensemble 1 (its electric bass pick patch is not one)

// 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.
