How to use midi controler for a CV out (or anything else)

Hello

The sun is back for my panels I can finally work again with my studio :slight_smile: after working on all the installation

So now I wanted to affect a controller from my Akai MPK9 to a CV out but didn’t know where to search for that !!!

Then how do I do if I got for example an enveloppe to that CV out and I want to affect the midi controler to the offset of this enveloppe ?

I just think now maybe it is to do in the matrix ?

Thanks for your help
