// 103 bpm, 4/4, key D# minor. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: pitch bends are ignored
// note: duplicate parts dropped: ch 3 "gUITARRA b" distortion guitar (copy of ch 2 "gUITARRA" distortion guitar); ch 5 "vOZ b" lead 6 voice (copy of ch 4 "vOZ" lead 6 voice); ch 7 "sOLO b" overdriven guitar (copy of ch 6 "sOLO" overdriven guitar)
// note: Full arrangement: all 136 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.

// 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.

// bass · electric bass finger · "bAIXO"
