Restoring a backup has fixed this issue for now. meaning I revert back to older firmware if I want a reliable unit live!! So many bugs. Surely Kemper would have a few guitarists trying to break the software before a release. Why are we the customers the lab rats??? very poor experience.
I used to test software for a living. It wasn't music software, but, my guess is Kemper takes a similar approach.
The software company would design the changes, perform their own Alpha Testing, then they would have third party Private Beta testing. After that, Public Beta Testing would be performed. The actual Production Release would follow.
Alpha and Private Beta testing were always likely to discover issues that would be corrected before Public Beta testing would begin. The usual reason for Public Beta Testing is this: The sheer number of Public Beta Test volunteers make it more likely for any remaining issues to be discovered in a relatively short period of time.
Public Beta Testing isn't for everyone - it requires a lot of extra effort. The safest way to do it at the same time as gigs and recording is to make Backups, then install the Beta software, do the testing, provide testing feedback, and then reinstall the Production software, and restore the backups.
As it indicates in the Beta documentation, Kemper recommends not using Public Beta software any Production use - that would definitely include live performances.
