Emu XL-7 & MP-7 User's Group

Hi everybody,

I got an XL7 a couple of weeks ago and have just been trying to learn the basics of preset patch writing etc. and now the thing will not start. 

When I turn it on I get a line of dots on the screen and then a lone cursor and that's it. It just stays like that. Before when I turned it on every LED on the thing lit up, but that doesn't happen now, just the dots and then the cursor.

Maybe useful info:

The last time I used it I was trying to edit patches with Prodatum. I have a mac running 10.6.8 I was unsuccessful there, I could get Prodatum to read the preset, but I couldn't get the info going the other direction. A couple of times I got an error message about sysex on the xl7. I was going to keep messing with it today to see if I could work it out.

Any help would be great, thanks!
