>>What drives are good replacements? And does it require some fearful
patch rewiring?<<

use the search function & look through old posts about the drives;
there's only about 450 messages here total so it won't take long! :-)

many of us have replaced drives- they don't last forever, sadly, &
they do get thrashed on these machines, especially if you do a lot of
sound design/sampling of y'r own, not just library stuff. look for my
old posts- I once made a point of collecting all the compatible drive
types into one post.
now- what's this "cinged" chip? I don't get how one fault can affect
all the voices, like you describe. can you tell us more about this?
I have schemos for the 2000/2002 somewhere... all the voices are
separate until the output amplifier stages, so if they're all
affected, it's either a screwy control voltage affecting all the
filters (yes, they're analogue cv's inside these things) or the output
audio stage.
it could just be a $1 op-amp that's failed.

duncan.
