I came upon this very very old post (homo erectus era) because I stumbled upon the same problem: Kontakt bass was too low and transposing Kontakt did not work (notes were lost).

In fact, the solution suggested elsewhere (Option channels Bass transpose 1) does work but YOU MUST RESTART BIAB.
Just in case someone encounters the same problem.
