[sdiy] XR2207 VCO

[James J. Clark]

Hi everyone, this is my first post here, but some of you may know me from
the Nord Modular or Reaktor lists.

I have been working on a number of DIY projects building some Doepfer
format modules. I have the details (some still sketchy) on my web page:

One module that might interest you is a VCO based on the XR2207 VCO
chip. I had a bunch of these lying around and thought it would be fun
to try and make these into a synth VCO. As it turns out, they make quite a
respectable VCO, with a very high quality triangle wave. The linearity is
sufficient for synth purposes. I have some comparison of the VCO with the
Doepfer A-110 on my web site.

Of course, any comments would be welcome!
