// And You Don't Remember — Mariah Carey
// 80 bpm, 6/4, key A# major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (6/4 at bar 1, 3/4 at bar 4, 6/4 at bar 5, 3/4 at bar 25, ...) are rendered on a constant 6/4 grid of one bar per cycle
// note: Full arrangement: all 54 bars on a 24-step grid, each part at one level. Source detail keeps the original performance.
setcpm(80/6)

// 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.
