I don't mean to pile it on, but the last thing anyone would expect is a musical device not to have some external editor, in this day and age when Mixer's have wifi and are completely controlled by an APP, I don't think it's even too much to expect ability to control this stuff using any smart phone never mind a computer editor.
Frankly, I also think Kemper would sell more so it's not just a minority that use editors, probably the majority of Kemper users have used modelers before and I can't name one that didn't come with an editor (even if I could name one, that's just one ). It's almost the equivalent of buying a car that has no radio or mp3 or music player of some sort., but in that case you can go to some local shop and buy a stereo and have it installed.
My advice for all the companies that make musical instruments, specifically those that are intended to be used in recording, don't just make an editor, make an editor with some sort VST or any connection to DAWS so that users can call patches from their recording software sessions and edit right then and there Plus saving the preset inside the session.. Eleven RAck inside of pro tools was a great feature, so it can be done inside some sort of VST or AU. Don't just settle for a basic editor.
This is not fictional stuff, POD Farm, had a dongle in the audio interface and processing was done inside the computer 15 years ago. I don't mind if my whole Kemper hardware turned into some big dongle and I can run triple profiles on three different tracks just like using a plugin . Why not, it can't be hacked, ask line 6 how they did pod farm and linked it to the audio interface...
