I am completely stumped and need some help. So I am trying to use a Soundcraft Signature 10 mixer as a hub for multiple inputs (guitar, mics, etc) and have the mixer output go into the iPad mini to use with looping software like "Loopy HD". First off you can't plug in direct from USB on mixer into iPad mini camera adapter as it says it requires too much power, so I tried using a powered hub and that made that error message go away. The problem is that I can't get the signal into the iPad in anyway? I don't know what to do and have tried nearly everything. Maybe I am not understanding the soundcraft as USB functionality or maybe I need that camera adaptor that has the built in power support or maybe I am an idiot and it is much simpler? Lol, anyway, I just want to get the sound from the mixer via the USB connection on the mixer to the iPad mini to route thru the looper app then somehow route it back to the mixer which would route to speakers. Is this possible?? Thanks for the help in advance!
