I saving thing is somtimes a two part operation depending on what you've edited. One is the Preformance and the other is the USB folders. Once you understand it it is not that hard but I had trouble too in the beginning. Same thiing with the OT settings. At first I couldn't get them to save but now I wonder why did I have all that trouble. Keep at it.
The obvious answere came to me about changed settings from my USB. I edit and save on my BK9 in my studio, Before a gig I transfer to 3 other USBs for backup and also onto my MAC. Then when I do a gig I'm using my second BK9. Somewhere in that chain I'm getting a mis- write. 32G USBs are chaep so I'll have to try some new ones.
Thanks
