Thanks for all of that Mike - it was pretty much similar to what I have read myself. I will give it another go...especially as the Pro actually "sees" and powers the iRig - haha the iPad doesn't! IIRC I did check that under developer ops, but maybe worth a try again, in case the "swipe" didn't quite take and I backed out of the options page too quickly..

Will let you know

PS: You also need to have the iRig connected before powering up the tablet, and again, I'm reasonably certain I did this, but I will check again.
