Hi all,

>I will have an EG (0v - 12V) and I need to scale it according to a CV.
so I can adjust the effictly the height of the EG.

How about this one. Use the CV to control the height of the assymptote
of the attack phase. Sustain can be simply a ratio of the CV. Therefore
no need for a VCA or whatever at all. All done at the EG stage. I'm sure
Oberheim did this with the later OB-Xs using the CEM3310s.
