Hi there, I just received a nice ipad mini retina for christmas and I would like to know how I can connect it to my amazing Pod HD 300. I have tried to plug directly via USB using the USB photo adaptor... but not recognized by the tablet... What can I do? ... I am sure my POD HD Can be used as a preamp and I don't need to buy an additional device, any idea? Thanks and merry christmas to you all
