hmmm... I thought it might be some sort of on-chip interaction betweem
them... makes sense...

However, this thing dosent have to be very precise... its intended for CV
control of my modular.  Was hoping to build 2 or 3, so as not to have to
turn 3 knobs, and adjust volume, all at the same time.. 1 hand waving around
in space and 1 knob seems better to me.  :)

Any ideas on HOW I might get it to work?  I already have it built on
perfboard and dont want to abandon it as of yet... Considered building a
couple paia kits for this... also a full theremin with pitch->CV converter,
but thats too much work.  If somebody's has another (cheap, easy) suggestion
I'd love to hear it.  I'll probably mess with it a little more and go ahead
an build one with 3 seperate 4093 chips...

Christian.
