Have only tested on one machine (MadMapper 3.7., but MadMapper seems to work well. Have tested multiple quads, video codecs. Only tested one output though.
Only issue seems to be the cue system / panel. it seems to function, but the GUI is unresponsive until you resize the window. At that point it will update values BUT you can't enter stuff in live or see the GUI's response in real time. Otherwise, works great.
Will keep ya posted on here.
