Hey guys, I've got a POD HD400 that I'm attempting use as a external soundcard for my Macbook Pro. I just purchased some new Yorkville YSM 5 monitors, and new XLR cables. The back of the POD is set to studio, and I've updated the POD with Line 6 monkey, and restarted my comp numerous times to no avail. If anyone could give me some help I would be very thankful!
