in 4.2 the rectishaper changed, therefore the sound of some profiles changed heavily...
before that the older delay types changed, when the older delays got
replaced by the legacy delay...
or volume settings of the input and so on ...
i don't know if there is enough space on the memory of the kemper to
leave older versions of the effects untouched and in the new version but
it would makes sense like in my case at the moment ...
also the volume and routing settings go to a default state after
installing a udate right ? there has to be a way to implement these
settings into the updated version ...
like install new firmware->yes/no, keep settings->yes/no that way
people don't have to setup things again and a complete newinstall would
be possible too
But i'm extremely thankful about all these great updates, i hope i can use them soon
