// Wasting My Hate — Metallica
// 148 bpm, 4/4, key G major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 5 "Gtr II (dis)" distortion guitar (copy of ch 4 "Gtr I (dis)" distortion guitar)
// note: Full arrangement: all 76 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(148/4)

// Notation: c3@3 lasts 3 steps · ~ is a rest · [c3,e3] is a chord · [...]/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.
