Korg Poly800/EX800 Users

OK I think I managed to fix it... must have been some junk code in the
global parameters registers.  I just now figured out where those were
and they were coming up all alien characters.  I went through and set
them all to 0 or 1 whatever the lowest number was and my keys started
working again.

I'm looking forward to that manual.  I feel like Stevie Wonder right
now trying to feel my way around all these new features.
