Toy Theremin connects well

Hello everyone,

I just wanted to share my success of connecting the toy mini theremin from ThinkGeek to my Werkstatt. I created this instructable and YouTube video of the build: and

What's cool is that the theremin outputs a 4.8V square pulse which is coupled to the output of a 386 Op Amp inside the Theremin. I figured it was safe to directly send this signal into the inputs of the werkstatt, but as a precaution I used a 10K pot as a voltage divider. As a result, the theremin easily alters filter, VCO, etc.

I bet one could use the same signal as a clock pulse for logic gates and counters, maybe further modifying the sounds possible.
