Was wondering if someone could shed some insight into an issue i'm having with a preset. The preset itself is using about 82% of the CPU, it has 3 scenes setup and they all transition properly. However whenever i switch to a different preset and return to this one, there is no sound. The amp defaults to a Bassman and all levels are turned off. Once i manually go back and turn the levels back up and return the amp to the AC30 model it was originally set as and save it again everything is fine. Until I switch to another preset and return to this one. And then the same issue occurs, it reverts back to bassman with all levels turned off. I'm assuming there is a setting/controller i'm missing here, was wondering if anyone had any suggestions as to what would cause this to happen. Thanks in advance.
