Introducing the uVCF state variable filter.

This is another great David Dixon filter design that has been on the workbench for a while. It is a very clean and precise filter that also doubles as an excellent sine VCO.

It responds very well to FM and the small size should make it a nice choice for smaller systems/lunchboxes.
