Hey @LeeFX
First, thanks for the answers on the marketplace page, much appreciated! 
I’m still evaluating things at the moment, but I’d like to get a Muse 2 because: a) it’s cheap! - b) it’s a great, sleek design.
I’ve done some research in order to get a deeper understanding and I might have found a solution,… not sure tho, so any feedback is welcome!
Assuming OpenVibe really works with LSL ( http://openvibe.inria.fr/how-to-use-…r-in-openvibe/ ), this little tool could help maybe? https://.com/kowalej/BlueMuse
LSL+OpenVibe+BlueMuse+BCIUE4 = WIN! 
I found this too: https://.com/labstreaminglayer/plugin-UE4 - just not sure if it fits in the picture…
Cheers
Alex
