parametric ranges than acoustic properties.

Then, what happens when certain older than sin parts have no Spice model?
It then goes into the 'create life' as the first process step kind of deal

But let's say one pulled it off, then everything you want to control it with
would also have to be within the spice realm  And assuming you got those
other circuits successfully replicated as well, for the $$ you'd have to
shell for a computer powerful enough to handle the size of the now 'patched'
spice model for the standard synth VCO into LP into VCA oldie,  you could of
hired a team of solderists to do the work for you!

Plus, it's sort already been done with DSP anyway in regard to the Moog:

does it sound anything like the real deal?  Nah....but it's fun.  Notice
their official description eludes to this:  "Software Synthesizer BASED on
the classic Moog Modular Synthesizer. "
