As with any other modular synth application, there's no "right answer", but
presumably the pitch->CV output will control a VCO, the envelope follower
output will control a VCA, and the gate output will trigger an EG that
controls a VCF. That sounds like a minimum requirement to me.

I have both both a Korg MS-03 (dedicated pitch->CV box) and MS-20
(monosynth with "external signal processor" including envelope follower and
pitch->CV). In my experience, the MS-03 is pretty worthless, BUT the
MS-20's pitch->CV function is pretty decent and very usable as long as you
have "clean" technique (if you're using it as a guitar synth) - I've even
found it to adequately track a bass guitar signal (low frequencies
understandably take longer to "lock in"). Having highpass & lowpass
filters, and a signal amplifier at the signal input helps, too, since that
lets you cut out harmonics that might interfere with the tracking and lets
you tailor the signal level for optimum response. The main problem with
the MS-20 is that the CV output is V/Hz (which could be what accounts for
its good performance), so it's not MOTM-compatible without an exponential
converter (unfortunately I don't have a MS-02). I'd buy a clone of the
MS-20 pitch->CV section with an exponential converter built-in for V/oct
response in a heartbeat!

... unless you're looking for the "Baba O'Riley" effect. Semi-random
arpegiation from chords through a pitch->CV unit can be very fun.
