I think it would be cool to have a Kemper Floorboard unit that works with your main Kemper. The floor unit as I see it would not be able to make profiles and instead you would download your rigs into the floorboard unit. The display would be simple and show the patch name and number. The effects are already on the switches. The outputs would be a simple XLR L/R and 1/4" monitor out L mono R stereo. Pedal 1/2,MIDI in/out, aux input, headphone,USB connection for computer or stick. Two expression pedals. Offer one rotary knob and arrow keypad. Add a switch for performance/Browse patch mode. The only onboard edit would be a simple output EQ and volume/gain setting, main/monitor level, head space, pure cab. Then offer the phone/computer app to offer a little bit more editing but the editing is basic bass /mid/ treble/presence.and effects.
To summarize...the floorboard would basically be a Kemper player unit and made for the rigours of the road, is made to be used with or as a stand alone player that you would buy profiles to use if you did not have a Kemper Profiler unit. You would upload rigs from your Kemper Profiler and could just bring the floorboard to gigs. Offer the unit with a soft bag and optional road case.
