That's too bad. I'm sure one of those does tune the filters. This
might not help either, but what stereo mode are you running your
evolver in? You might get slightly better results running in St1 mode
and using only one of the outputs, since in mono mode you are
actually getting the summed oscillation of two filters whose
frequency is never *exactly* the same.
It's strange that this would work for one person and not for
another...analog is as analog does, I suppose.
