Florian, I see that the second possibility would mean also to spare a VCA (which are never enough), though I still believe that it would be necessary to adopt a VCA with «two» cv inputs, that is to have two control voltage inputs on the VCA module in order to modulate the amplitude through both EG and velocity voltages. Or there's a step I missed in the understanding of the patch? Maybe you just intended to mix the two signals... 


Best, Diego

As for the velocity to modulate amplitude besides gated envelopes, do you mean that the velocity voltage and EG voltages should be mixed together and the sum sent to the unique VCA control input? If I am correctly following, I believed that this way they would mutually affect the result of each other. That's why I was thinking to rely on a 2 cv inputs VCA, one for the average amplitude (velocity) for each gate, the latter for more detailed amplitude “drawings”… Maybe it would be just the same result... 


if you mix the velocity voltage with the envelope voltage and feed the sum into one VCA, it will cause the VCA all the time a little bit (according to the velocity voltage) and the evnelope will add on top of this basic level. 

You have two possibilities: 
1.) Use the envelope and a first VCA, as you do it always, and then add a second VCA after the first one which is controlled by the velocity. 
2.) send the envelopes voltage through a VCA, and control this VCA by the velocity voltage. The result will be an envelope voltage whose amount depends on the velocity. With this modulated voltage you can control again the audio VCA as you are used to do. 
The advantage of solution 2: you send the audiosignal only through one VCA, which will be better for the audiosignal.
