... and if that doesn't violate your bank account!  I mean, come on --
does it *really* make any sense to shell out a couple hundred bucks or
more on a MIDI->CV box to control something on the order of a PAiA

Or am I woefully ignorant on the subject of how cheap a MIDI->CV box
can be had for?  The lowest price I know of is for the Fatman (with a
synth thrown in for free), at $150 if you don't mind doing the
soldering and making your own rack panel and if you're driving linear,
not exponential, modules.

Seems like, if PAiA can put that into a $150 synth kit, it ought to be
possible for a DIYer to build a simple MIDI->CV module for under 40
bucks.  In fact, why not build the digital section of the Fatman?  

If one did so, would it be merely a software (firmware) hack to make
it drive exponential modules?
