Weird volume issue with newest update

    I made a new performance based on a 69 Marshall MBritt profile . Today I turn on the Kemper and the volume is very low and the effects are barely hearable.

    Kemper is hooked up to my Apogee audio interface like from the first day. I reboot the Kemper and the sound is back to normal. But after 20 minutes i lose 50% of the volume again.

    I reboot again and it is back to normal..

    I am at a loss of what could be the issue.

    Newest rigmanager with editor installed and about 800 profiles and 20 performances on the Kemper.

    Any expression/volume pedal attached to Kemper or Remote? That was the reason for some here a while ago that they encountered an effect similar to the one you describe.
