SynthModules

After precisely calibrating the module, the new PSIM consistently
outputs a sampled cv that is higher that the other PSIMs that are
similarly trimmed.  I know that this is a moot point for those who
have only one PSIM, and, for that matter, I can run Mike Firman's
quadrature lfo program on the new one and use the older units that
match for other stuff, but, I have to wonder - is there any difference
between the old and newer PSIMs?
