MOTM

A signal wire combined with a ground wire in a twisted pair won't make much
difference as far as signal quality goes.  The twist just helps with
cable/wire management.

MOTM tends to ground through switched jacks highly sensitive or precision
unattenuated CVs such as 1V/octave inputs.  It is overkill for anything
else.  As far as I can tell, you may not even notice a difference if you
don't ground the precision inputs.
