Been using M=PC for control of movers via a Beringer midi unit, alongside a venues FatFrog. All live bands on the fly busking. Want to be able to use the DMX out of the FatFrog i.e. use the control surface to interface to DMX in on m-PC. What licence do I need to have to enable DMX in from Entec Pro or do I need to buy a M-DMX ?
