Hi,
I work with Ableton and MIDI too and experienced that if I switch Rigs in Performance Mode the Kemper „freezes“ from time to time. The only solution is to pull the cable because even the Chicken Head Button is not working anymore.
Have you ever experienced something like this?
Do you have both a USB and a MIDI cable connected to the Kemper?
I found that the Kemper doesn’t like that very much, which is kind of annoying since sometimes it’s nice to have Rig Manager open when doing automations.
