It's just 1V/Oct normal CV stuff. Easy enough to use an R/2R ladder and
an opamp for the scaling. Look for a workshop manual for any 80s
analogue/digital crossover synth (such as the infamous Roland TB-303 or
SH-101) for an example of such a creature.
I have a couple of parallel I/O cards for my PDP-11 that I'd planned to
do just this very thing with. Haven't done it yet, though.
