If you have Cynthcart, you may not know that a `paddle` enables you to control filter cutoff and assign another control on two knobs. There are a number of tutorials on this, but most of them are very convoluted with errors. So, here we go:
You Need:
- 2 x 240k LOGARHYTHMIC potentiometers*
- 9-Pin cable (female connector)**
- Enclosure
- Wires
- Soldering Iron/Solder
- Multimeter
First identify the wires that are connected to the female connector. You can do this using a multimeter and a wire placed in the relevent holes. The holes you need to hook up are: Pot1, Pot2 and +5v.
This site explains the pinouts

Now, solder the wires to the potentiometers making sure there with be enough slack to fit them into the enclosure. Both get Pot1/2 and the +5v.
Once they`re soldered, get the enclosure drilled with two holes. I used an old joystick base for my enclosure (It looks like a robots face!)
Attach the pots to the enclosure, close it and put the caps on. Test it, then you`re done!
*with 480k I found they only have an effect for 50% of rotation.
**make sure you have a connector that features the correct pins
- the one in the picture is from a C64 joystick and doesn`t have pins
for the paddle controls.
