Perhaps this is a problem on the Mac OS, but it's not like that on Windows.
It's an even bigger problem on Windows because Windows doesn't provide an option at all to aggregate multiple audio interfaces into one.
I don't know what kind of studio you're referring to but every DAW and computer system that I'm aware of only supports ONE audio interface at a time. If the Kemper was your audio interface in the studio then you might have to teach me how you would record anything else (like vocals or drums or bass or a second guitar or keys) at the same time.
I'm quite sure that many people aren't remotely aware of the limitations of audio over USB usage.
