So just for laughs, here is my start up sequence:
One iPad is docked….
Power up airport express, wait for it to boot.
Power up DL, it then makes the iPad power up.
Load Master Fader 2.1.1 on docked iPad. It then syncs with the DL (get pop up window announcing sync)
I then load whatever saved scenes I need to use.
Power up remote second ipad, make sure it’s connected to airport express wireless, load Master Fader on this iPad. It syncs to docked ipad or the DL itself. (Not sure which)
This has worked every time. Of course this all has not been used in the real world yet, so I may be in for a lot of fun dropping sync etc. when I do a real gig at an important venue.
