Ok guys, I have amplitube 3 on my laptop, and I can't get my guitar to communicate with it. I've tried adjusting mic settings, equaliser settings etc, even tried plugging the guitar in via my iRig. Can't get anything but an annoying buzzing/humming sound! Anyone have any ideas what I'm doing wrong? Tried the ASIO settings, MIDI settings... AAAARRRRGGGGHHHHHHHH!
