// 124 bpm, 4/4, key C major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: sustain pedal (CC 64) lengthens the held notes
// note: duplicate parts dropped: ch 8 "LENNON / McCARTNEY" tremolo strings (copy of ch 3 "VOCAL" piano); ch 5 "STRINGS" string ensemble 1 (copy of ch 4 "STRINGS" tremolo strings); ch 7 "VOCAL" piano (copy of ch 6 "VOCAL" piano)
// note: Full arrangement: all 67 bars on a 32-step grid, each part at one level; ghost notes are separate "_soft" parts. 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: edit a riff to change every repeat.
