MOTM

Richard - ah - thanks so much for clarifying - my use of
"interference" was imprecise to be sure - I was using it in a very
broad sense.

We're new at this and we really appreciate your advise.

OK - well - we are also trying to be proactive - and because of that,
we probably will add another 900 eventually.  That means we need to
anticipate space for it, of course.

We're also considering moving to a somewhat narrower 39 inch wide
three-tier layout for our synth as opposed to our original 48 inch
wide two tier design.  This will leave more space for expansion, make
patching a little easier, and make the power supply seperation of
digital vs other modules a little easier to do in the context of our
layout - just in case it becomes an issue.

Thanks so much again.

Bill and Will
