I have the Focusrite Saffire Pro 14 and was getting confused with the combination of its mixer and Cubase 7. This lead me to this thread and after reading I set about it again and my problems were solved. So thanks all.
I was getting a delay, the same kind that the “Turn Global Off” option in older versions of cubase would solve. Also, each time I did anything to the Saffire mixer Cubases metronome would fall silent.
Both these issues were sorted by selecting “Daw Tracking” in the Routing Preset menu, and then selecting Asio Saffire in the Device Set within Cubase.
So,
Saffire Mix Contol > Daw Tracking
Device Set up Asio Saffire
I don’t sound like I’m playing in an empty arena now.
