Yeah man. . I uaed BIAB 2010. In "Audio MIDI Setup" I created a new external midi device. I don't know why I did this, but Andrew, the support dude told me to. I then connect the ins and outs from my EWI USB that that new external device, which I named "virtual EWI." THEN, inside BIAB, I Choose MiDI Ports, and I get this weird blank line. I choose that weird blank line, then close everything and it work!
It's that easy! ha.
