+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. +

+ independent can be used to control the default behaviour when
+ making a copy of a MIDI region.
+
+When enabled, every new copy of a MIDI +region results in a copy being made of the MIDI data used by the +region, and the new copy of the region will refer to that data. +
++When disabled, every new copy of a MIDI region will refer to the same +MIDI data, and thus editing any copy will change the contents of all +of them. +
+Changing the status of this option has no effect on the existing + dependent/independent status of existing region copies. +

+ Other Copies. The copy is now using an independent version of
+the data, and edits to the copy will affect only the copy. Other
+copies will continue to share data.
+
Note that the copied data only covers the extent of the region when + the copy is made. If the region was already trimmed and then a copy + is made, an independent copy will have no access to data that is + earlier or later than the bounds of the region it was copied + from. Put differently, if you make an independent copy of a trimmed + MIDI region, you cannot "untrim" it to a larger size. +
