here's a site with all the MIDI specs: -- click on HARDWARE for interface.

From the little I know about stage lighting - they use a dc voltage
(0-10v) to control dimmers. So to begin, you'd need an A-D controller
that can work with REV, such as the one describe earlier last week:
One whole bunch of dimmers I control, in a big house, use 0-10VDC
per dimmer which we make in other ways. Another whole bunch of
dimmers I control, in a theater, can use DMX-512. That is a looped,
multiplexed, time-divided system (each device has an address (0-511)
that determines its time slot. For all I know, common DMX-512
interfaces may have 0-10VDC outputs.
Like Stephen says, its pretty easy to get at MIDI if you can do
serial. Old mac serial ports could do it directly, but I haven't
since.
