<DIV>I'm looking to start experiments with VCOs. I've put this off for sometime due to the seemingly precise nature or temperature compensation and my lack of understanding.</DIV>
<DIV> In my setup right now I have dosens of modules (VCFs, VCAs, EGs, etc.) but only 2 VCOs (Synthesizers.com) capable of accurately tracking the keyboard (V/oct). I'd like to build four more, though not necessarily the same designs.</DIV>
<DIV> I've been looking at a T. Henry VCO <A href="http://www.midwest-analog.com/vco1.html">http://www.midwest-analog.com/vco1.html</A> and the Ray Wilson VCO http://www.musicfromouterspace.com/analogsynth/August2003VCO.html. I have a couple of tempco resistors (Midwest Analog) which both circuits (can) use . I'm most interested in the Patchell VCO that looks tempco free, which appeals to me. I would also like to add accurate tracking to my VCFs, again, tempco free. </DIV>
<DIV> I've seen some info on temp comp but any links and/or info would help a lot. Also, suggestions of VCO designs and experiences would be greatly appreciated.</DIV>

<DIV>Thanks,</DIV>
