// Look Away — Chicago
// 108 bpm, 4/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: track names are the Roland MT-32 patch names at their program numbers ("Bass" on 68, "Brass" on 95, "Trombone" on 90, "Warm Bells" on 38, "Vibes" on 97), so with no bank select the whole file is read through the MT-32 patch table: ch 2 "Bass" Slap Bass 1 -> slap bass 1; ch 4 "Brass" Brs Sect 1 -> brass section; ch 5 "Trombone" Trombone 1 -> trombone; ch 6 "Warm Bells" Warm Bell -> pad bowed; ch 7 "Vibes" Vibe 1 -> vibraphone
// note: duplicate parts dropped: ch 7 "Vibes" vibraphone (copy of ch 6 "Warm Bells" pad bowed)
// note: Full arrangement: all 85 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(108/4)

// Notation: c3@3 lasts 3 steps · ~ is a rest · [...]/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.
