Stop guessing and start testing.  Begin at the VCF CV input and work back.  Check to see that if you hold a key with the VCF EG amount set to minimum that it actually holds a steady voltage.

The joysticks seem to lose their dead zone and go noisy.  This makes the pitch bend, VCF mod and VCO mod go apeshit.
