There is no need to design anything, MIDI light control is already available from any one of at least several sources.

It can get pretty complicated in a hurry, though, and I don't recommend trying to implement such for a one man show anyway. YMMV

For a one man show, there are likely only going to be two to three scenes that work well, tops. This can be handled with some rather simple footswitching.

Of course, if one wanted to utilize currently available MIDI light controls for that purpose, it could be done, but I think I'd still want to keep it separate from the songfile playback used during performances, I'd likely use a programmable separate MIDI footpedal device to fire the lights. And, it would be more flexible in use, as you could pick the scene to fit the venue rather than be locked into scenes painstakingly programmed into the songfile sequencer.

But at that point, the two or three scenes for a one man show could easily be handled by hardwired footswitching...
