With a true stereo panning control like the pan controls in NOTION 3 and NOTION 4, if you pan the Master stereo output to top-center, then you have a monaural output, where the technique is to move the Left and Right dots to top-center (or "0"), really . . .
Really! 
P. S. There are three dots (Left, Center, Right), and they need to be set to "0.0 pan L", "0.0 pan C", and "0.0 pan R", respectively for
monaural, except that you only need to set the Left and Right dots, because the Center dot will be in the middle automatically when you set the Left dot to "0.0 pan L" and set the Right dot to "0.0 pan R" . . .

P. P. S. This only works with a
true stereo panning control. It does
not work with a balance control, since a balance control only adjusts the relative volume level of the left and right channels rather than actually moving the panning location of the channels. And as noted, NOTION 3 and NOTION 4 have true stereo panning controls,
not balance controls. This is easier to understand when you know that the Left dot is a monaural panning control for the Left channel, and the Right dot is a monaural panning control for the Right channel . . .
