Look at Thomas Henry's site at his 8038 circuit.
http://www.midwest-analog.com/diylvco.html

The same approach to making an 8038 not suck can be applied to the 2206 and
as mentioned before on the list there is an upcoming book from Thomas Henry
about abusing the 8038 and 2206.

I've built several of the 8038 vcos to play with.  The waveshapes are nice,
but the chips are relatively expensive and since I make PCBoards anyway the
minor additional wiring of just building a 4069 based VCO makes it
preferable.

I do have some XR2206 VCOs, they are plain-jane Jameco function generator
boards which I use as LFOs.
