// Star 69 — R.E.M.
// 250 bpm, 3/4, key E major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Full arrangement: all 251 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.

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