to me,
there has always been.... until recently,.... some confusion that Master Fader suffers with in this regard, and it has been the "accurately displayed" snapshot dilema.
For a long time, during a show and while I was mixing, I would create a new snapshot and give it a time, let's say 9:30. I would expect immediately affter naming the new snapshot, that the display (upper right-hand corner) would be updated to show the current running snapshot. But for quite a few years now it hasn't. I have gotten in the habbit of creating and naming a new snapshot, and then immediately hitting "recall snapshot" to force the window into displaying the correct snapshot. I do not know what versioin it was but this odd behavior has gone away and acts properly now.
So, It has been too long since I have had a DL1608 and don't miss the issues related to the "docked or not" iPad. Apart from my experience with this problem, it has no longer been a problem.
Now,... for a 1608 user, and in my opinion, the docked iPad should NEVER even have the ability to run a different show than one that is already connected wirelessly and is succesfully running the loaded show/snapshot.
If for some reason, you are experiencing a different show running on a different iPad, and it failed to give you the pop up window "the DL is running a different show that this iPad.... blah blah blah... that is scary. I would for sure contact Mackie via phone and ask them if in fact my help here has not answered your questions.
