Actually midi seems to be something that drives an led inside the opto-

As long as the two "signals" are not connected to anything besides the opto-
coupler in the receiving device, all is well.
The book on my desk with electronic-nifties for studios labels the two pins
used by midi as signal+ and signal-...

Why do you want to carry 5V? According to my
docs, Midi is just Signal+
and Signal- and shield. Which, when carried over Cat5, should be all on
the shield.
any midi has to carry 5v iirc. and midi is not balanced, so there is
no
signal+ and signal-. would be cool if there was - then 100m would be no
problem :)
