MOTM

paul, 
care to shed some light about what exactly is going on in this scope 
snapshot?
I follow the 1200hz squarewave in and then apply a  .5v to the cv in 
to increase the amplitude.
Is it the fact that the wave no longer looks anything like a 
squarewave, and that a VCA (obviously)shouldn't do that?(especially 
not a 380 dollar one)
