Yes.  If you want to have only one copy of a chorus plugin (which you
almost certainly do), you want to have that as a monophonic node.  This
is what the page on the wiki is all about.

Make sure the "polyphonic" checkbox in the load plugin window is not
selected when you add the node.  You can't change it after the fact.

FWIW, I usually keep the polyphonic stuff in a subpatch, and run it
through effects in the parent patch, to keep things seperated and more
flexible in the future.  This is a better practise - there should
probably be a page on the wiki about "good Om practises" like this.
