Agreeing with the others....
The Mobius (or FR777 version) is an excellent way to control some Serge
modules. I *haven't* had to do anything special to ground the two.
The grounding issue seems to vary a lot and often from day to day. In my
case I've used the FR777 may times with my Serge and just run cv and gate
cables to the banana/mini jack adaptor strip I had Rex put on the space next
to my Frequency Shifter.
