How do I use Playback markers to change patches?

Q. How do I use Playback markers to change patches?

I have looked all over the net and nobody seems to have found a solution to this... at least in MainStage 2.**

But we are on MainStage 3 now and I would think this has been addressed.

It seems that since there is midi info enough to 'Cycle' between Markers then we should be able to harness this info to change patches as needed.

I am currently using MainStage 3 on a MacBook Pro (mid 2010) running Mavericks (IMO MainStage 3 behaves better in Mavericks than in Yosemite)

Thank you.
