I have similar experiences to Nev with LX programmers. Most of them don't mind adding a blank cue or two to allow a bit of conducive MSC triggering, but that is generally as far as it goes.

Medialon is a big hammer to crack a small nut - most modern moving light desks do MSC quite well. I've used Medialon very successfully to control Catalysts via MSC, but it is a very expensive solution.
