Has anyone ever had the following issue before? I set up three performances: P1- Voxac30, Diezel vh4, Peavy5150. P2- Bogner XTC, Bogner Uberschall. P3- Blackstar S1, Driftwood Purple Nightmare. I used an FCB with the UNO for Kemper chip as the controller. After switching through the performances for some time, the amps in performance 1 mixed and they all changed to the peavy 5150.
