Which logical operator do i need for this problem
 
I want to create a polyphonic/paraphonic synth of 4 voices. I'm getting 4 SE oscillation, a not yet decided wavetable osc (either 4ms spherical wavetable or SE Quadnic). I also have the SSF quantum rainbow for different noises. Now, I don't see the reason to get 4 of them, so what I want to do, is using the gate signals from the midi interface to if one of the 4 keys are pressed, or multiple are pressed and released in different order, I want to keep the noise VCA 'open' until all keys are off. Ideally, it should be able to follow one envelope.

Am I right to use the AND operator or should I use OR here?

My developer guts say AND, but OR seems also possible.

What would you guys/girls advice me?

This isn't what modular is for. I'd buy a nice poly to integrate into the rest of you modular stuff instead ... you'll save money and prevent lot's of headaches in the long run.

Well, the beautiful part is that want or not, you can do it. The other oscillators are covered and ill be fine. Just want to know if above will work, if or if not, how/why.

You'd use OR. With AND all of the gates would have to be high for the output to be high. Refer to this table I stole from the Internet...
