A Modification for the people who are not so much into that "holy original" thing...
Just checked the envelopes with the scope. The AR is pretty slow at the rise (around 7ms rise time), and pretty fast on the fall time.
That is as designed - but I just don't like it.
If you have such short envelope times as the ARP has (with its 1uF cap), than they should be capable of having a short attack.
It is adjustable back to what the original timing was, just move the fader up a bit. So no jump from "next to zero" do "several ms as soon as slider is moved" as you often have on synthesizers with 10uF envelope caps.
add a 2n3904 instead of 1n4148
connect the 2n3904 collector with a 1k resistor to +15v
base and ermitter instead of 1n4148 holes /see picture
