I can only talk from my own experience. My BK-9 sometimes acts up. It happened to me that I tried to save stuff in the performance memory, just to realize that nothing has changed the next time I selected that performance (after the keyboard was turned OFF and turned back ON). Yes, this happened. Does it happen all the time? >>> answer is "NO". Yes, in my opinion, there might be a glitch in the software somewhere that surfaces every once in a while, but for the majority of the time it works as it should. In my case this happened after I updated to version 1.06. TEds, can you tell us what version your BK-9 is on currently?
