You can control the Main mix and the two Phones channels via the UFX Volume knob.[/quote]
I am aware of that, but you have to push the volume controller in to switch from Phones1, Phones2, and Main (which controls both speakers A and B). So with that setup, I couldn’t do a quick A-B-C comparison. I can do a quick A-B comparison, but in order to listen to C, I would have to turn the main volume all the way down, press the volume controller to go to Phones1 (where I would have monitor C connected), and then turn the volume up. Although that can work, that really isn’t a feasible way to do quick comparisons.
If I were connected to the Cubase Control Room directly, I would just have to press one button and the volume would stay the same on each monitor pair. I just wouldn’t be able to use the volume controller on the Fireface UFX.
