Thanks for your time and suggestion Peter. It seemed such a simple
and elegant solution that could be easily overlooked that I was
excited to try it out. However, the only reset procedure in the
service manual I could find is the one to clear the memory for the
patches, which I had done a number of times while reloading SysEx
data. I tried it again for good measure (a couple of times even) and
still nothing but a scratchy slider sound is produced when keys are
pressed and the volume slider is moved.

It seems far fetched, but I suppose something could have happened to
the volume slider during my battery replacement. I've tried already
tried deoxit, but perhaps there a simple way I can bypass the volume
slider completely to test it other than replace it? IE, Can I insert
something into the circuit that sets the resistance open at full
volume? Again, please forgive my electronics naivete if that sounds
ignorant or uninformed, I'm an unemployed philosophy major by trade.

If necessary, I'd be willing to even pay a few bucks to any kind soul

of a fix (other than the obvious -- bad volume slider). *The board

I'm pretty certain the volume slider worked just fine, before I
replaced the battery for the patches because it did make noises,
albeit random ones. *My multimeter also detects resistance change on
the slider when I move it up and down. * One other strange thing I
noticed is that when the audio is re-routed, the detune slider doesn't
detune -- it seems to affect a parameter value -- a filter perhaps?
The slider that is supposed to change patch data also behaves
similarly -- no increase or decrease in patch or parameter value, but
instead a change in the parameter value.

Is there a 'hard' reset for this unit? (The Kurzwiel 250 has a button
inside on the CPU board, for example). If yes, do a hard reset first.
