UR-RT2/Cubase artist/mac problem with sound


I just switched to a new audio interface and ur-rt2 works fine, I can hear what I’m playing with my external keyboard but when I open Cubase artist sound disappears. Also artist lets me hear pre-recorded audio from my old files but not midi, though midi info gets through, sound does not. I can also record audio playing or singing but hear it only on playback. It may be some simple thing but can’t figure it out.

Hmm, when I select from cubase device setup asio driver the “built-in audio” I can hear midi sounds through speakers connected to Ur-Rt2 but audio sound comes from mac built-in spekers but when I choose “Ur-rt2” I hear no midi.
