Hi, brand new member here! I have a vfx sd, I recently got a disk which has some sounds on it, loaded them and everything was great for a month. But now I can only access 2 of the 60 sounds I loaded from the disk, the internal Rom sounds are fine. I’m also getting weird scrambled language on the display when I go through the banks for the ram sounds, as shown in the picture. Anyone know what is going on? 
On Ensoniq boards, reinitializing is always a good first step. I would try that, then reload the programs from disk and see if the machine is happier.
