Xpantastic!

I powered down my xpander and it was working perfectly (pass every tuning all the time after I recapped the ps years ago).  I turn it on a few minutes ago and it behaves like there is a note stuck.  Playing midi notes will change the note that I hear.  Also all tunings fail.

I tried a system reset, it did nothing.  I tried to change the pedal stuff, but it did nothing.  I'm really hoping someone has an idea of what this is.  I really want to finish the song I was working on and I kind of need this instrument.

Thank You,
