I volunteer at a church running their weekly productions/services. I need help with my Leprecon LP-X24. It is no longer saving patches that we install when the board gets shut off. We have the main patch backed up on a floppy but I can't have all the volunteers learning how to upload a patch every time we need to use it. I looked through the user guide but didn't see any reference to a memeory backup battery. Can someone please advise? Thanks!
