Cheers- Yesterday I had the chance to mess with a Zerocillator at analog haven.. needless to
say I was underwhelmed. I had grandiose ideas of it's FM and what it would sound like.. 
hmm.. I'm searching for that classic square wave sound of the CZ101 range of gear.  I think 
they used a slightly different Phase Distortion type of FM, and that may be why the sound was  
so good.. anybody else make a FM module?  

Thanks -Coleman.
