Thomas Henry Strikes Again Subject description: Another very cool VCO by the Man from Mankato
From way up north, Mankato way, land of a thousand lakes and even more synth designs, comes a new VCO design from Thomas Henry. Grab your spare 3080 and put it in a safe place.....
Thomas calls it a workhorse VCO - Expo FM, Lin FM, triangle, PWM and one hell of a pure sine wave. On top of that, in typical Thomas Henry fashion, it is an elegantly simple design - I was amazed at how quickly I breadboarded it. But, don't let the simplicity fool you - this thing has got an *amazingly* accurate 9 octave range and it plays beautifully. I love this little VCO already. Page to come, schematics, PCB layout, the works.
Here's a quick sample of it - no big musical event, just the VCO piped through the Mankato filter I've had on breadboard since the summer of 2004. I modulate it here and there with an LFO, and the PW is modulated by another LFO (the wave heard is the PWM wave). And, of course, I use my patented Too Much Reverb(R) effect. Of course, it's the Thomas Henry keyboard controlling it.
Remember, this is with no tempco with a patch held together with alligator clips. I spent about three minutes tuning the VCO (it tuned easier than any VCO I've ever dealt with, don't know why - of course, I haven't tuned it to the gnat's ass yet - I'm having too much fun ).
Coming soon to an Internet Near You.

Hi Scott. Let me tell ya, that sample you put up sounds absolutely beautiful! I gotta build this new VCO and the Mankato filter. I have a decent stash of 3080's, about 30 of them! Its time to use some.

I get this feeling that I'm the unlucky copy of myself that got stuck in the parallel universe that never had the Henry synthesizer sitting next to the Moog in Tomita's studio. Or maybe I'm the lucky one - I can afford this synth
I'm thinking the web page will be very soon. Thomas sent such a wonderful narrative, I don't think I should alter a word of it - I'll probably concentrate on formatting it for the page and let you all read it as it should be read - I just got done reading it myself, and walked away with a much clearer understanding of expo converters and transistor based Schmitt triggers than I ever had before.

It's OK, Photon, I got this one..."Oh, the pain, the pain....."
Indeed exciting news, Bill! In the meantime, I'm off to check what this UD-1 business is all about.

I'm hoping to have a usable page up by the end of Monday, just to keep you all on your toes

I'm unfamiliar with "gnat's ass" tuning.
It has been proven that the frequencies produced by the flatulence of the common midge (often referred to as a gnat) at sea level closely follows the mixolydian scale, in very, very high C. This is opposed to the stepped range generated from the expulsion of methane by the common fruit fly, which is generally pentatonic, though there is considerable variation among species. However, it is the midge that is consistently mixolydian across all species. Thus, the reference to "gnat's ass tuning".
This is also explains the common term "I'm gassier'n a mixolydian fungus gnat", made famous by John Wayne in the 1962 Paramount Pictures release "Chitin and Git'in".

I also liked the definition from the urban dictionary, which states that a gnat's ass is about one tenth of a skosh (which is equal to approximately one nudge of the dial, amounting to something much less than a pussy hair).
