Here´s an overview on the Doepfer A-179-2 Light Controlled Voltage Source, followed by some ideas and patches to utilize light controllers in creative ways.
I think you did not mention the jumper for the gate out derivation. I think for many it might be more intuitive to adjust this as otherwise the gate is always on until you move your hand near when probably you would rather have it come on when you bring your hand towards like striking a drum. Also the documentation does not give the voltage ranges.
