I can't update in my rack, theres only a 2" hole in the back for cords to go in, I cant get my hand in to hook up the computer cable! If that's all it is, then I wont bother. Would it be possible in the future to update it so when your programing and you move a slider it gives you a numeric value for where that slider is set? This could be very usefull for setting speeds and colors etc... Is this something that would even be possible to add?
