What i need help with is what exactly do i need
i have downloaded the software and it seems simple enough to use / Im an IT guy

seems i need a usb to dmx controller here is where i have no clue what i am doing. i suppose what to get depends on what i want to do. well i simply just want to be able to control my lights.
I have purchased 4 mini spots from ebay. upon doing research they seem to be the same thing as the minspot by chauvet.
My main goal is to be able to control there function. and possibly add some of my other lights but thats later on
i also have these lights that are dmx capable colorail,kintax,fallout .
So if your still reading after all of my crappy writing skills lmao i would like ot know what else i am going to need - links to products would be great!!! as i have no clue what usb-dmx controller i need
