I've owned my Kemper since 2018. I've read in the forums that a lot of people have had issues with OS updates. I've read people complaining about their tones, profiles, performances, effects changing or sounding different after updating to newer OS. I would love to know from Kemper if these updates do in fact change the tones or alter what we have saved in our Kempers. Is what we have saved in our Kemper supposed to change after OS updates? I would love to hear from you guys especially from people at Kemper. I'd like to add that I haven't sensed or heard a difference in my profiles and performances. Just curious after reading others on the forums that have had issues.
