Well, the Rig Manager helps a lot ... you could just keep on the unit what you regularly use, and limit experimentation to when you're connected.
Thanks. That makes sense. I think I haven't figured out yet how I can have rigs on the RM but NOT having them on the Kemper!?
I always import new stuff via USB and see them afterwards in the RM.
I am not connected to the Internet with the Recording PC. BTW, I Regularly get the message "some rigs are damaged..." from the RM. Am I doing anything wrong?
