How do I get Cubase 9.5 to recognize my Motu Interface? It only recognizes Built Inputs and Outputs.
Is a MOTU Interface suppose to work with Cubase? It works with Logic 8, I Tunes, Audacity and Logic.
Yes it should work.
Please list your Cubase version, computer operating system, Motu model.
If you are on a win 10 pc, do you have the latest motu asio driver installed?
Regards. 
This is actually more a question for Motu than Steinberg.
But presumably you need to download their “Audio Installer”
