I roll my own out of guitar cables I have laying around that I cut up.
Usually Belden, but for patch cables it's important to have the heavy rubber
cover, and a woven copper mesh ground, not the foil and drain wire kind of
ground. Also, for me it's important to find a cable with wire that solders
easily. Seems like a silly requirement, but I have seen some cable that
absolutely refused to take solder.
In other words, get something similar to what would be used to make a high
quality guitar cord. SOrry I don't have specific wire numbers.

The 6th lug is probably a chassis ground. Don't use it. One of the points
about MIDI is that it avoids connecting the chassis grounds of the two
devices it is plugged into. MIDI only uses 3 connections. I don't have the
connector pinout in front of me, but it is the middle 3 pins of the 5, with
ground being the middle one. So your cables only need 2 wires plus ground.

I'm going to build a panel for my Expressionist also. I'll be adding gate
lamps to the 8 gate outputs, and will build the LED drive circuits on one of
Paul's breadboard kits, if I can figure out how to cram everything on the
panel and still leave room to mount the circuit board support legs.
