Anything with 1N4001 diodes is probably a power supply.  If you replaced
these
and it still doesn't work, measure the output of the supply with no load
and
then with a load.  If it drops way down with the load connected and maybe
an IC heats up, there you go, call em and get a replacement IC.  The DSP
chip is probably an "one time programmable" part unless you see an eprom
somewhere.  So it would have their special code on it and you need their
part.  Take the board out and send it to them - if it really has so few
parts it shouldn't be an issue with them. 
Expect a 5V supply for the digital and DSP stuff.  Who knows for the
analog.

Barry, 
	Well, I found out that there is a bunch of bad caps that were all in line
with
the diodes. I suspect these to be all bad. Ill replace them all. It also
turns out that there
is a chip (the horse with no name DSP) thats overheating pretty bad, and
its surface mount.
I need to get a surface mount station. I could use the one on the Natnl
Guard base, but they 
dont like it when I use top secret govt radio repair equip to mess around
with synths :)
I think this is a total wash. I know whats wrong, but I seriously doubt
that Quasimidi will
sell me something that they deemed secret enough to scratch every little
bit of writing off
of.. If replacing the diodes and caps doesnt work, im sending it in.. In
retrospect, i doubt it
will cost as much to repair as it is to buy a new one UNLESS they are like
Packard Bell.
