This is what the external CV gate mod for a Polyvox (Polivoks) looks like.

It works now. I had a problem with mine but we were able to trace it to a defective scale pot that was used for the mod and a mistake in the first set of mod schematics (since corrected).

A HUGE thanks to Vladimir Kuzmin for drawing up the mod and then troubleshooting it.

And a big thanks to Shawn Cleary (who sold me this synth and then worked with me when there was a problem)
