For me there are not enough controls. I had different controllers like the Behringer BCR and the BCF and the iPad with Touch OSC. I think it is a process and depends on the way you want to work. It can be mix of different controllers. What's the great thing on the ipad is you can changes the layout of knobs, sliders and pads in any way you want. You can change so often as you like and check out what's the best for you.
