Hi Brian and welcome to Yamaha Musicians. Just closing down for the night when I saw your post and off the top of my head the thoughts are either an EX7 main board in the EX5 or EX7 firmware perhaps. Do you have any of the history of the EX or can you get it? There is a lot of commonality between EX5 and EX7 but also some significant differences. Keep us all posted and we'll see what we can do to help.
P.S. Run the diagnostics if you haven't already to see if they tell you anything (VOICE+H+8 together).
