// You've Got a Friend — Carole King
// 102 bpm, 4/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: ch 6 "Strings (BB)" named as a string part, played on string ensemble 1 (its vibraphone patch is not one); ch 9 "Bass dbl" named as a bass, played on electric bass finger (its string ensemble 1 patch is not one)
// note: sustain pedal (CC 64) lengthens the held notes
// note: duplicate parts dropped: ch 9 "Bass dbl" electric bass finger (copy of ch 8 acoustic bass)
// note: Full arrangement: all 106 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
setcpm(102/4)

// 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.
