Jim's reply to me there seems equally apropos here, plus more detailed, so I'll paste it in, and will happily ditch my thread to follow this one, assuming whatever you find re VCV rack will be as useful for other virtual devices.
As eenixon mentions, CV signals in Numerology are floating-point numbers -- i.e. the same values used for audio. Also like audio, it is a 'stream' of values instead of discrete messages (like MIDI or OSC). This is a very powerful way to represent an arbitrarily moving signal, but can be very much overkill for many types of musically useful signals -- like note numbers.

Here's a short guide to how to pick the most efficient, but still accurate way to send information around:

Use MIDI For: Medium resolution and medium update rates. Everything from note values, triggers and gates, and many, many synthesis parameters (frequency cutoff, LFO speed, etc). As tempting as it might be to use CV for everything, you can often get by with just MIDI -- and it works with just about anything. One thing to watch out for though: It isn't difficult to saturate a MIDI interface with Numerology-generated notes and CC messages -- but IAC busses are software are generally OK w/ high-data-rate MIDI.

Use OSC For: High resolution and medium update rates. Slow moving LFOs, frequency values, etc.

Use N4 Pro's CV2Audio and a DC-capable audio interface for those cases where you really need both high resolution AND high update rates. On a modular system, this typically means audio-rate modulation of some sort -- say a fast LFO, or a weird quickly moving control source (wogglebug). With something like Reaktor, you can use and audio input and an envelope follower to convert an audio-rate control signal into something it can use internally.

I tracked down more on Volta, btw; seems both expensive ($200+) and old, as well as unlikely to be really universal.

I've always wondered whether the most straight-forward application of some more cash towards this goal mightn't simply be some cheap-as-possible DC-Coupled hardware interface that could easily pass what's routed out to it right back inside for virtual distribution. I'm also hoping that Bitwig Studio will have some useful tools as well, as my Reaktor inquiries have suggested that BW works easily with CV/Audio straight out of that.

Been getting cool results with Dialog Audio's new MIDI FX plugins inside Logic (MIDI only, so far), btw; highly recommended if you're using Logic.
