[sdiy] monolithic VCO chips for FM??

[Scott Stites]

Hi,

Not to be mysterious, but I've actually got the first draft manuscript of Thomas Henry's forthcoming book on using some off-the-shelf (current production) generator chips for VCO's.   AFAIK, the book is imminent (not related to another DIY book he's doing which is further down the pipe still).  I discussed one of the designs with him about a week ago, and he mentioned that he got perfect expo freq doubling/volt linearity up through 6 kHz with one of the designs, with ~1.99:1 or so above that.  Definitely musically useful.

The designs are comparatively easy and as soon as he releases the book, I'll spill the beans a bit more (can't right now pre-release).  

Cheers,
Scott

Hi guys,
Just wondering if there is an offshelf monolithic VCO chips available out there?
It would really make the circuit much smaller and easier to make, am thinking
about building a multi VCO circuit with patching points for some FM, may be there
is a kit out there? :)

Thanks again!

You guys are an AWSOME bunch!!!!! :)

Can't wait to do some patching and knob tweakin!!!! Well, I'll need to do some
soldering first......
