The first method that comes to my mind is to use a comparator at the 
gat input with the negative rail tied to ground, the positive rail at 
+12V or +15V, with 4V at the negative comaprator terminal and connect 
your gate in to the positive terminal of the comparator.

I need to make a bunch of these for my modular, too.  I've got 7 VCO's, 
5 VCF's, 5 VCA's, but only 2 EG's (ouch).

Just messing around with the attached circuit over here..   it seems to =
give a more desirable range when i present 12v on the gate..   how can i =
mod this to accept 5v? =20
i've tried a few experiments with a transistor (which i'm almost =
positive is the answer), but i don't know enough about them to make it =
work..  anyone, anyone?
