// Crazy Train — Ozzy Osbourne
// 67 bpm, 4/8, 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: pitch bends are ignored
// note: duplicate parts dropped: ch 3 fretless bass (copy of ch 2 electric bass pick); ch 6 overdriven guitar (copy of ch 5 distortion guitar)
// note: Full arrangement: all 169 bars on a 24-step grid, each part at one level. Source detail keeps the original performance.
setcpm(67/2)

// 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, A@4 for four bars: edit a riff to change every repeat.
