Paul will tell you that distributing audio signals on a buss is asking for
noise and crosstalk. Control voltage signals would be less sensitive - you
might think of distributing kbd and gate information. You still might need
to drive the signals with a simple op amp unity gain buffer.

Should work fine. I plan on having an angled front cabinet that is 26 units
wide and 10 units tall. The middle will be supported by 2 L shaped rails
fastened together either to form a T or a U (T is easier but I'm not sure if
the hole spacing between the 2 rows will allow for it). L brackets on the
end is what I was going to use, but not the flimsy ones you buy at the
hardware store. And avoid bolting them through from the outside - you don't
want a bolt head messing up that beautiful piece of hardwood you paid dearly
for, now do you?

BTW, folks should avoid aluminum for the rails - it's too soft to tap good
sharp threads into, and won't last if you move your modules around much. Use
iron or steel.
