That would still mean at least one key is down. In the CV/Gate realm 
there are no really events, just voltages.

I disagree. I'll leave polyphony aside since I doubt that Girts has a 
polyphonic synth with a single pair of Gate/CV jacks. :-)

If you "mix" CVs by adding them then you can OR your gates. Since then 
the MIDI input and Keyboard really transpose each other. So you want 
sound when either source signals a key is down. The other option is to 
take the maximum or minimum of the CVs, then its still reasonable to OR 
the gates. This would be like on a monophonic highest (or lowest) note 
priority keyboard, with more than one key down.

Cheers,
  René
