Saving Audio Effect Racks - M4L stored within?

    May 02 2013 | 3:30 pm
    Hey, I just did some tests with saving M4L devices inside an Audio Effect Rack.
    When saving the rack and deleting the original device, reopening live and loading the rack the m4l device was still there. That's awesome, so I guess the Patch is saved within the Rack.
    However when I made two racks, that shouldn't refer to an existing patcher, and changed something in one of them, it changed for both?
    Anybody can bring some light in this situation?
