My good friend, a few years ago, controlled 20 slide projectors, independently, with a Commodore 64, something everybody said impossible to do. He, to this day and age is the go to guy for computers in our community. In Ninth grade, he wrote the computer curriculum for the local School board for all High school grades. His Aunt and Uncle won 13 million, gave him a 3 Million trust fund, for nothing but computers, at the age of 11. I suspect you have no similar story.
Your best bet, visit a quality Music store and see what they recommend. Most bands have that done at the Mixer stage, out in the middle of the audience, with production house rental equipment.
