MOTM

I am running the + out from my EG into my VCA and - out into FM1 of my 420
and everything works fine.  I don't have any way to reverse the polarity of
the - out, so I ran the + out into the mult and then took two signals from
there.  No good!  Neither the VCA nor the filter respond to the EG when it
is set up like this.

What gives???

Thanks!
