I have two things that would enhance the performance mode for me:
1. The whole performance mode divided in "setlists". Lets say 8 or more. Each Setlist opperates just like the normal performance mode, with the posibility to save different Setups.
I'm playing guitar in different bands so I could use one setlist per band. This would be a great feature.
2. "Intelligent"-Assign. Many people are using different midifootcontrollers for the KPA. Some of them have 3 or 4 or 5 presets per bank. In order to use the performance mode you can only use a footswitch with 5 presets per bank.
In the "intelligent"-midi assign, the kemper changes midi depending on how much slots you use for each performance.
So if the first performance has 3 used slots the midi Prg for the 1. slot of the second performance is automatically #4.
If the second performance has 4 used slots the midi prg for the 1. slot of the third performance is #8, and so on.
That would make it easier to use performance mode with all kind of footcontrollers.
