[sdiy] modular theremin or modular VCO

Howdy,

 Naturally there is going to be all sorts of interesting things going on as 2 ultrasonic waves produce an audible beat frequency. There is going to be all sorts of phase shifting all the way up the ying/yang, the effect of 2 frequencies you (theoretically) can't hear but, psycologically, they are doing some subliminal fol-de-rol in your brain via your ear parts. as far as harmonics generated when 2 such waves interact, I don't know, but I'm sure threr's something going on there also. The Frostwave beam controller is cool, I got one somehow when I bought one of their sequencers. It does not compare to a genuine beat frequency machine. Get the Paia. You may want CV only for now, but sooner or later, you WILL want to do "more".
