I just did have a look at this, you can not assign KAOS parameters to the sliders. Unless i missed an OS update. But i don't think thats the case.

This makes the same features on the Genos much more accesible. Being able to assign this to the sliders would be a step forward tough for KAOS.

You also can not controll these PA4x parameters over midi.. i am talking about the various parameters you can assign to the X and Y Kaoss axisses.
