// Ringo Starr — The Beatles
// 90 bpm, 4/4, key C major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: metre changes (4/4 at bar 1, 2/4 at bar 14, 4/4 at bar 15, 2/4 at bar 24, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: pitch bends are ignored
// note: ch 2 "Lead - Clarinet" named as a reed, played on clarinet (its contrabass patch is not one)
// note: duplicate parts dropped: ch 7 "E.Piano 1" piano (copy of ch 3 "E.Piano 1" epiano1)
// note: Full arrangement: all 82 bars on a 24-step grid, each part at one level. Source detail keeps the original performance.
