Hi, I've found that the following realtracks:

#1040 -Organ, B3, Rhythm JazzBallad Sw 060 ('A' only)
#1041 Organ, B3, Rhythm JazzBallad Sw 060 ('B' only)

plays A and B parts despite their names. The same happens with other similar realtracks, like #1046, #1047, #1049 and #1050.

Maybe others can replicate the problem. I'm up to date.
