Need support for Midi Device Plugin in UE4.14

Could anyone lend some advice on my current blueprint? I have managed to print out the device name of my midi controller, so i am sure it is recognizing, but I cannot for the life of me get it to print the 0/1 of when I hit a button. I think my problem lies with the SET node (I used promote to variable from create controller) but it could be the event nodes too. Any help wold be appreciated, as I am running out of time unfortunately.
