f2v 1a

[tomg]

Well...I don't think the 331 f2v is going to work out.
It's kinda neet as a novelty. My wife and I had tons
of fun singing into a mic letting the vco track us.
But I don't think it's going to work out.. We will
see. I got most of the ripple out of the cv using
diodes and a cap on the output of the 331. But
if you sustain a note for more that a second or
two there is a beat as the 331 resets......it
sucks!

btw: if you try this remove the 10K resistor from 
pin7 to gnd. The threshold is a little screwy.
