Cubase 9.5 RME UFX II problems

I’m running Cubase Pro 9.5.41 on a Mac (high sierra 10.13) but am having problems with the new RME UFX II interface I recently purchased. The output is fine but anytime I monitor an input channel, I hear a pretty terrible digital distortion to the sound. If I monitor the input through total-mix is sounds absolutely perfect but the second it hits Cubase, I get something similar to bit-crushing or maybe even sample rate reduction. I have updated the RME drivers and firmware and again, it works just fine with core audio.

I searched around the forums but couldn’t find anything that seemed relevant. Can anyone help me please?

Thanks,

Hi and welcome,

Do you use Direct Monitoring? How is the routing in the RME Mix?
