Faderport questions


I’m thinking about picking up the PreSonus Faderport and was hoping someone who owns one can answer this.

Is the “output” button dedicated to the master channel (stereo out)? I basically just want to use it as a dedicated master fader and transport controller.

If there is a work-around through Cubase that would be great too.

Thanks for any insights.

edit: looking through the manual

“The Output button access to your main output bus fader (Cubase/Nuendo only).”

“The FaderPort will also follow the channel selection
within the DAW via keyboard or mouse.”

Now for my needs, is there a way to disable channel selection via mouse and have just control of the master at all times?
