JL, I am on the verge of getting a Rack, but the x-18 whenever it hits the market may do for me. Looking at literature and the like I am uncertain about a few of the rack's features. When you record multi-track to the ipad, do you use the back usb to 30 pin connector on the ipad? And if you can access the rack in this manner, can you control all parameters with the ipad through one of the usb's in the case of a wifi issue? Sure would rather do that than be restricted to the front panel controls. Thanks.
