I just got an FCB1010 MIDI controller for my unpowered Profiler having researched lots of different MIDI controller options and found this was the best non-Remote option out there. Just my luck - it seems the latest update to the OS 7.1.19 has a problem with it and the Kemper crashes if any MIDI commands are sent to the Kemper. Looking around on the various Facebook groups others have the same problem. It worked up until 7.1.15 but whatever was added in 7.1.19 - probably the support for public release of RigManager 3 - has broken the support for external MIDI. Or at leas tthe FCB1010. I have th stock firmware that came with the FCB1010 - another guy on the group is using the 3rd party Uno4Kemper firmware in his FCB1010 with the same problem.
I updated to 7.1.21 in case tyhat fixed it, but same issue. Screenshot of the error below for anyone else who hits this...
(Before the system crashes completely it hangs and a # is displayed on the right hand side of the screen under the 'E'.)
I've emailed Kemper support...
