Yes, Rogue will work with all KMI controllers that have an expander port. That includes the QuNeo, QuNexus, 12 Step, and SoftStep.
For the QuNexus, 12 Step, and SoftStep to work with Rogue you will need to acquire a rather uncommon USB cable. You will need a male mini-USB to female micro-USB cable in order to connect the Rogue to the Expander port on your controller. Once that is connected it should behave just like a QuNeo would.
