// Predictable — Korn
// 160 bpm, 4/4, key A minor. 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, 9/4 at bar 70, 4/4 at bar 75, 9/4 at bar 147, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: duplicate parts dropped: ch 4 distortion guitar (copy of ch 3 overdriven guitar)
// note: Full arrangement: all 171 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(160/4)

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