Did you ever get it figured out?
It sounds like a tricky one to try and pinpoint the problem. All I can really suggest is check all cables and footpedals and any other connections and volume levels on everything.
If none of that works I'd probably try a reset of the amp but make sure you have all your favorite patches saved and backed up somewhere first.
