Good ol' Google got you here. But further searching has thus been fruitless.
You're trying to find documentation (or vids) explaining how to set up multiple additional Master Fader 5.2 apps to access the DL16S in your rack, but only in a limited capacity.
Specifically, you'd like to know how to allow your bassist to access *only* the Aux mix to only his monitor, and how to allow your vocalist to access *only* the Aux mix in her monitor, and same idea for your drummer.
This can be done with either the internal router or with an external router.
Confiscate their phone or tablet. Download and install master fader. Using their device, connect to the wireless that allows access to the DL16S. Start master fader. Use the wireless icon to discover the DL16S. Use the gear icon to reveal "Access Limits". Use the gear icon within that page to select "All On". Then, deselect the Aux mix for their monitor to give control back. Select the lock icon. Turn your back to them and type in a number you can remember (strongly dissuade '1234'!)
Done!
Hand their phone or device back to them.
