Hey, I’m new to unreal 4 and this could very well be that I’m an idiot and missing something but I’m trying to get into the DMX side of unreal but every tutorial i watch when they go into DMX library they have a tab called controllers where you can create a new DMX controller but in mine it isn’t there and i can’t find a way to get it. If someone know how to fix please it would be helpful to me. Thanks
I have the same problem. 
did you find a solution?

Where on earth do you get the GDTFs. See point 4 here:
Hey, so I’m very new to the DMX side of Unreal, and wanted to share that I was doing a little digging after running into this same issue. I noticed that in 4.27 the DMX project settings are dramatically different. It looks like you control the amount of universes as well as protocol name there instead of a controller panel contrary to what the documentation says

Hey, I did not see this until just now, but eric is correct. The controller tab was removed and instead we have project wide “port” settings for DMX so you don’t have to set them per library. You can then select which port you want to use in the library. This will continue in UE5 and there are some expanded settings for locally over-riding the IP addresses, etc… through command line.
