[sdiy] cv schematic help

[Caleb Johnston]

Synth Experts,

I need help with a basic CONTROL VOLTAGE schematic. (I'm a novice)

I am trying to have multiple joysticks send CV out.

My schematic works for one axis output.  But when I wire the second axis 
(let alone another joystick) then the cv axes interfere with each other.

Two 9v batteries hooked up in series to each other.  So then I have a + 
volatge, - voltage, and ground (the middle).  One end of the joystick pot 
goes to -.  The other end of the joystick pot goes to the +.  The middle 
joystick terminal pot goes to one end of the jack out.  Then the other end 
of the jack out goes to ground.

Sketch it and it is easy to see.

This works great for one axis, but try adding another and they interfere 
with each other.

Any help would be appreciated.  Send me a sketch or text.  Thank you so 
much, in advance.

-Caleb
