dammit. I misread cs15 for cs5.... um.... no, that sounds like
something else. it could be two faders gone bad, or else the synth has
had some power-supply mishap in the past that killed both eg chips....
I would have to look at the schemos. I expect that part of the cs15 to
be broadly similar to the eg2/eg3 of the cs30. ok, theories presently...
