I have the same audio interface and yes, it does work. You can route your tracks (mono or stereo) to every out-port of the interface.
As soon as the interface is connected cubasis activates 6 ins and 6 outs.
You don't need a driver for ios7 - there is no way to install an audio drive on the ipad. However there is a new firmware for the Komplete 6 - you need to install the interface first to a mac or pc, and install the new firmware there, then you simply connected the interface to the ipad and it works.
