// Time in a Bottle — Jim Croce
// 138 bpm, 3/4, key F major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 8 "MELODY" ocarina (copy of ch 1 "MELODY" accordion); ch 5 "GTRSTL" acoustic guitar steel (copy of ch 2 "GTRNYL" acoustic guitar nylon)
// note: Full arrangement: all 96 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(138/3)

// 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.
