I think it is most common use to use CC for this. Any CV-to-MIDI box does 
this, as far as I know.
The higher CC messages do not have a fixed meaning in the MIDI specification, 
so they are open to interpretation.

so the messages would be CC - cc no - cc value

Channels are used to distinguish between different MIDI devices, so that is 
how you are supposed to do it too. Make it configurable on your box with some 
DIP-switches maybe.

If you do it like this, you can also use your MIDI controller to control 
something like a Nord Modular, where you can assign Midi CC to (virtual) 
knobs in your synthesizer patches. And you won't even have to bring your 
computer to a gig then...
