To do it, you need 2 midi cables and the unochip....its won;'t do it out of the box.
The dispaly isn't great but it does work..Just to check I wasn't imagining it, see below from the Uno website ( uno4Kemper)...
Anyway, just an idea...
UnO stands for "UnOfficial" (= not created by Behringer). UnO firmware solves some annoying bugs and adds some frequently requested features. To name just one: in "stompbox mode" you can use 1 row of FCB1010 switches to switch effects on/off, with the LEDs showing the current state at all time. Initial stompbox states can be programmed for each preset.
UnO4Kemper firmware is a completely different beast. Instead of an allround programmable MIDI controller, the UnO4Kemper equipped FCB1010 becomes a plug-and-play remote control for the Kemper Profiler. Configuration is kept to a minimum, no programming required. 2-way communication assures that the FCB1010 LEDs are always in sync with the Profiler. Even the Profiler tuner can be shown on the FCB1010 display.
