Sorry. I don't use Realband.
If you play a fast bebop tune (230 and faster), at the B section the drums suddenly go out of sync. It lags behind resulting in a very awkward sounding accompaniment.
I almost heard myself shouting: you can't keep time. Guess what? you're fired!


Biab, Kontakt, Sampletank and lots of nice libraries, from Fluffy audio to Abbey Road drums.
