on this type of dmx controller it is really just for playback. i believe you cannot adjust DMX values on this unit you have to have another controller to adjust the values on and then save the scenes into this controller. this is merely just a playback/edit sequence type controller. also these are discontinued. as far as hooking it up to a PC maybe in some way Compuware if u have it. but if u have it then might as well just use it. peace! jingles. any questions feel free to ask. welcome to the forums!
