Hi,
the title basicly says it all. Ordered the chip a year ago, everything was working nicely except the huge gap when switching between rigs in performance mode. However, a few days ago I unplugged the midi cable at the fcb and since then I can't get it to work with the kemper again. Do I need to reconfigure sth? Did I overlook anything?
You should plug the cable again into the FCB. 
Joking aside, is the cabling right (out to in and in to out, made the mistake myself repeatedly). Do you
power the FCB AFTER the Kemper? If this is all ok I'd open the FCB to check If something on the connection board became loose (it has happened to me with an internal LED driving one pedal not working).
