UR824 dspMixFX

Hi, I purchased a steingberg bundle consisting in UR824 interface and Cubase Pro 9.5. With the interface it comes a mixer software zero latence that I find quite handy… IF I COULD JUST RECORD SOMETHING THRU IT ON CUBASE! That’s my problem, I don’t know how to do to make it sound on cubase, I followed the instructions in the manual and I came up with the visualization of the signal input of it but never got any sound or a track in which I could record what is happening thru it. Does anyone can help me please? Thanx in advance
