It loads any Rigs from the big brother. I'm presuming that whatever effects you have in slots A, B, Del, and Rev would, and the relevant Rig settings would be dialed up on this Player. While anything you have in C, D X, and Mod from the big boys would be missing, and of course any effects the Player doesn't have.
It loads any "profile" from the big brother. For the rigs, it will depends on the effects used. You will probably have to rework your rigs one by one.
Also it can't load performances !
