Analogue-sequencer

Thanks,
For those who don't know, at RMI's recnt gigs there have been little
gooseneck lamps attached to their gear.
(see http://www.modulator-esp.co.uk/images/photos/misc/HJ4/rmi/02.jpg for an
example)
I thought it looked like they were connected to the midi outs of the
equipment and that they looked really useful. I looked high and low before
asking Duncan where he got them and had a sneeky feeling he might have made
them himself.
So would it be possible to do this with midi?
Cheers
Jez

OT- jez- rather a convoluted route to answer a simple question, but
here goes: the little lights are from a computer shop (e.g. maplin), &
come with a USB plug on them.
it's a tricky operation, but you can replace the USB plug with an XLR
& then add a corresponding socket to the back of y'r controller
keyboard. find the 5V regulator & take a feed off that via a
several-hundred-ohm resistor. the hard part is trimming back the
spring-steel goosenecky stuff to get at the wires inside.
emu saw fit to provide a bnc connector on the command stations for
such purposes- I wonder if colin could be persuaded to add one to the
p3..?
