Hello Kemper world-
So I couldn't find any threads mentioning this type of set up, so I thought I would put it out there.
This is how I run my stereo set up at home and I get an amazing sound. I run a guitar cab on one side, in my case the left side, and I run a DXR10 on the other side in my case the right. You get the amp in the room sound/feel from the cabinet, yet with the DXR 10 you get all that lush high-end goodness from the the stereo FX.
So it's pretty basic but in case it helps, the way to set it up is, (and I should mention that I have a powered Kemper) you go to the 1st page out the output section, and set the \monitor output\ to master left, and the \direct output\ to master right, done stereo set up. Obviously if you use different outputs for your set up you will need to adjust accordingly. You can then go to page two of the output section and control the volumes independently.
Hope that helps someone.
