how to get my XY pad to work on cubase 8 LE

does anybody know how to get my midi controller XY pad to work on cubase 8 LE?. I just bought this program called “Thrill” from native and I cant record any morphing or velocity of sound without an xy pad. Im using an M-audio Code-49 midi controller. I cant figure out how to get cubase and thrill to recognize my xy pad on my Computer (IMAC). any help would be appreciated, thanks.
