Greetings,
I can't seem to recreate this issue successfully, but my Kemper has crashed quite a few times while dragdrop'ing folders of profiles. (Mainly soundside, since they come in two seperate folders)
Halfway through the sync the screen just says Kemper Profiler and while the unit still produces sound I am unable to make any adjustments.
Rebooting the Kemper solves the issue ofcourse.
Edit: I will also mention that during the sync I am not touching any knobs or anything. The crash just happens by itself.
