How to get the looper working with any Midi Device (without external software): 
------------------------------------------------------------------------------------------------------------------------------------------------
If you have a Midi Device, that allows you to send four CCs at once, it is very easy:
Here are the commands:
CC#=Controller Number, V=Value
Rec/Play/Overdub: CC#99 V125, CC#98 V88, CC#06 V0, CC#38 V1 (on press), V0 (on release)
Stop/Erase:CC#99 V125, CC#98 V89, CC#06 V0, CC#38 V1 (on press), V0 (on release)
Undo:CC#99 V125, CC#98 V93, CC#06 V0, CC#38 V1 (on press), V0 (on release)
TriggerCC#99 V125, CC#98 V90, CC#06 V0, CC#38 V1 (on press), V0 (on release)
ReverseCC#99 V125, CC#98 V91, CC#06 V0, CC#38 V1 (on press), V0 (on release)
1/2 SpeedCC#99 V125, CC#98 V92, CC#06 V0, CC#38 V1 (on press), V0 (on release)
------------------------------------------------------------------------------------------------------------------------------------------------
If you have a device that allows you to send two CCs at one time (like FCB 1010 etc), it´s easy too:
I have recognized, that all commands need the same two controller numbers:
CC#99 V125 and CC#38 V1
The trick is to program one button as looper activator with this two values, if you set the midi running status “on”, the Kemper will keep this two CCs in his memory until you power it off
Then set up the other buttons:
CC#=Controller Number, V=Value
Rec/ Overdub: CC#98 V88, CC#38 V1
Play:CC#98 V88, CC#38 V0
Stop/Erase(press button 3 times): CC#98 V89, CC#38 V1
Undo/Redo:CC#98 V93, CC#38 V1
Trigger Start: CC#98 V90, CC#38 V1
Trigger Stop: CC#98 V90, CC#38 V0
Reverse/Unreverse: CC#98 V91, CC#38 V1
1/2 Speed: CC#98 V92, CC#38 V1
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
If you have a device that allows you to send only one CC it´s a little tricky – you have to split all the commands and put it on two buttons like this:
Looper Activation:
Button 1: CC#99 V125
Button 2: CC#38 V1
Rec/ Overdub:
Button 1: CC#98 V88
Button 2: CC#38 V1
Play:
Button 1: CC#98 V88
Button 2: CC#38 V0
Stop/Erase(press both switches 3 times alternately in succession):
Button 1: CC#98 V89
Button 2: CC#38 V1
Undo/Redo:
Button 1: CC#98 V93
Button 2: CC#38 V1
Trigger Start:
Button 1: CC#98 V90
Button 2: CC#38 V1
Trigger Stop:
Button 1: CC#98 V90
Button 2: CC#38 V0
Reverse/Unreverse:
Button 1: CC#98 V91
Button 2: CC#38 V1
1/2 Speed:
Button 1: CC#98 V92
Button 2: CC#38 V1
To retrieve the functions, both buttons must be pressed one after the other. This will work, but it´s a bit awkward to use (maybe for practise purposes).
I hope it helps some of you!
Thanks to the Kemper team that has made it possible! 
Good luck und happy programming!
