How about we just stop arguing whether it's a FR or a bug? It doesn't matter, he has a genuine problem and Kemper are trying to help him.
Because it may look like, that this "feature" needs to be requested and is not present yet. New users or potential users that are reading that might think "i do not want my sounds to change after updates, maybe the kemper is not for me then"
I know, this is exaggerated a bit, but it seems that he is already in contact with support. Therefore this feature request thread does not add to the solving of his problem.
