VCO out should go to the audio in of the Wasp filter. The out of your Tilt should go to the CV input of the Wasp and Gristleizer (for a classic subtractive patch). Out of the Wasp into the Gristleizer input. Gristleizer output into your mixer. Adjust settings of Gristleizer bias and Wasp level and frequency to taste.
Have fun!
