// Strange Brew — Eric Clapton
// 124 bpm, 4/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: pitch bends are ignored
// note: sustain pedal (CC 64) lengthens the held notes
// note: duplicate parts dropped: ch 9 "Lead" synth choir (copy of ch 8 "Lead 2" lead 6 voice); ch 9 "Lead" synth brass 1 (copy of ch 8 "Lead 2" synth brass 1); ch 9 "Lead" dulcimer (copy of ch 8 "Lead 2" dulcimer); ch 9 "Lead" tenor sax (copy of ch 8 "Lead 2" tenor sax)
// note: Full arrangement: all 110 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(124/4)

// Notation: c3@3 lasts 3 steps · ~ is a rest · [c3,e3] is a chord.
// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
