My first date with the Double Deka

"Here's a quick video made of SSL's interpretation of the Ian Fritz Double-Deka VCO. My usual caveats about lousy focus apply here too, sorry.

This is my first exposure to it in the flesh; it's literally been switched on for 10 minutes before the camera started recording! It looks much, MUCH better in person. The illuminated LEDs are a joy to behold.

What's going on: Bank A and Bank B of the DDVCO are set to 50:50 mix, but the mix is modulated at audio rate by a Dotcom Q106 VCO's sine wave output. That generates a useful FM-style buzz. This is routed through an STG Soundlabs Post-Lawsuit Lowpass filter. Initially the filter has a very low cutoff and about 50% resonance, but I dial back the resonance as I play with raising the filter cutoff level. Then it's into the VCA and out to a delay to add some echo.

There's not much else going on in this patch; about half the cables you see are from a previous setup I neglected to tear down. They don't influence the sound or provide any other control sources."
