The bass sounded really strange not like a bass at all. I think I figured it out somewhat. I am not sure how BIAB maps to the channels on SampleTank. I found the bass maps to Channel 2. The other issue (I have had this in Cakewalk) is the bass plays an octave too low. Is there any quick way to make the bass midi play an octave higher? You can do it easily in Cakewalk.
