There is no way to ensure that the current is split evenly. Also you are
still disapating all the current in one IC package unless you use two ICs.
I just discovered my ADSR is not on my website, I'll have to fix that. I
used transistors as the charge and discharge switches. They handle more
current than a 4066 and cost less. 2N390x are less than $.0.10 each.
