cubasis and scarlett 18i8

Hi there. Did your iPad easily “see” the i818? I tried to use a Tascam interface but my iPad 4 didn’t want to recognize it. I’ve been wondering about the Presonus Audiobox 1818 VSL. Actually I’m wondering about what would be the right interface for my needs. I’m hoping to record several track simultaneously. An electronic drum kit and electric bass, D.I.ed and miced so at least 10 channels. Hope you can help.

Thanks
