// I'm Only Happy When It Rains — Garbage
// 108 bpm, 4/4, key B major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: ch 1 "Piano Right" named as a piano, played on piano (its distortion guitar patch is not one); ch 2 "Piano Left" named as a piano, played on piano (its electric bass pick patch is not one)
// note: Full arrangement: all 118 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(108/4)

// 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.
