Downloaded 8.7.9 tonight. Within about 3 hours the remote pedal display went completely blank then the rack froze ... no response from any controls. Even when I switched it off it took about 5-10 seconds to shutdown !
I love the Kemper but this is not good especially if you're running live!!
I filed a ticket with Kemper for the same problem with 8.7.6 on the 10th July. Had to revert back to an 8.6 release.
Guess I'll have to do the same again ...
