3 When <dfn>copying a MIDI region</dfn>, Ardour has to decide whether to make the
4 copy refer to the same data as the original or not. If it does refer
5 to the same data, then editing either the copy or the original will
6 affect the both of them. If it refers to an independent copy of the
7 data then each one can be edited without affecting the other.
10 <h2>Changing dependent/independent copying for the entire session</h2>
13 <kbd class="menu">Session > Properties > Misc > MIDI region copies are
14 independent</kbd> can be used to control the default behaviour when
15 making a copy of a MIDI region.
18 When enabled, every new copy of a MIDI
19 region results in a copy being made of the MIDI data used by the
20 region, and the new copy of the region will refer to that data.
23 When disabled, every new copy of a MIDI region will refer to the same
24 MIDI data, and thus editing any copy will change the contents of all
28 Changing the status of this option has no effect on the existing
29 dependent/independent status of existing region copies.
32 <h2>Making an existing copy of a MIDI region independent</h2>
34 <kbd class="mouse">Right</kbd> clicking on the MIDI region to be independent
35 then selecting <kbd class="menu">MIDI > Unlink From Other Copies</kbd>
36 makes it independent: the copy is now using its own version of the data, and
37 edits to the copy will affect only the copy. Other copies will continue to
42 Note that the copied data only covers the extent of the region when
43 the copy is made. If the region was already trimmed and then a copy
44 is made, an independent copy will have no access to data that is
45 earlier or later than the bounds of the region it was copied
46 from. Put differently, making an independent copy of a trimmed
47 MIDI region only retains the visible part of it.
