Bars whose transcriptions are similar (16th-slot occupancy cosine >= 0.6,
diagonal-smoothed, and exact pitch/onset match >= 0.3) are treated as repeats.
Notes recurring in < 15% of a bar's repeats are dropped; notes in >= 25% and
>= 3 repeats but missing from the bar are added. Default on for guitar.
