// Childhood — Jackson Michael
// 90 bpm, 4/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: metre changes (4/4 at bar 1, 3/4 at bar 18, 4/4 at bar 20, 3/4 at bar 22, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: ch 3 "Bass" named as a bass, played on electric bass finger (its synth strings 1 patch is not one)
// note: Full arrangement: all 76 bars on a 24-step grid, each part at one level. Source detail keeps the original performance.
setcpm(90/4)

// 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.
