-When copying one or more MIDI regions, Ardour has to decide whether to
-make the copies refer to the same data as the originals or not. If
-they do refer to the same data, then editing any one of the copies
-will affect the contents of all the others. If they refer to a copy of
-the data then each copy can be edited independently.
