// 115 bpm, 4/4, key E major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 1 piano (copy of ch 5 electric bass pick)
// note: Full arrangement: all 69 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
// note: Guitar parts that double another keep only their own notes (fills, solos): guitar program 28.

// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
