uhh, the previous by john is almost in coherent to me. Dude, you're supposed to be helping people in this forum, not adding to the confusion!
I would like to report that also my Akai EWI USB is not working inside BIAB. I don't know how to do screen shots in here, but I can tell you that it works just fine as an input device in Finale, Logic Express and Garage Band. In the end, I cannot play melodies into BIAB.
