The issue: After not using the set-up for a few days, I noticed that the sliders on the keyboards would not respond, and would have to be reassigned in the rack editor mode. Also, volumes in the Arturia VST’s themselves would be set to zero.
The problem presented itself again last night. I unplugged both keyboards and after plugging them in, the situation corrected itself. I’m using my set-up right now and did run into any these problems.
OK – so this is a completely different scenario that what you described initially. I (and probably everyone one else) thought that Gig Performer was not loading your setups after you saved them, per your title.
What you’re describing here seems to be completely different. It sounds like your MIDI subsystem is not working properly, or something is going to sleep. You mention that unplugging your keyboards and plugging them in again caused everything to work again. How are your keyboards connected to your computer?
