Looks verry nice. I also noticed that all Steinberg UR series audio interfaces also connect to iPad via camera connection kit to Cubasis, another cool product.
Could be the future. Several of those little cameras might be used for videas (typo of video but I like it) soon too.
Several makes of mixing desk that work with a remote tablet also record pretty damn well from what I see.
Buy a PA…?
