Apple Logic Pro 9 - Manual (Page 892)

An alias can be assigned a staff style different from its parent region. (For information on
staff styles, see
Working with Staff Styles .) For example, imagine a melody that you want
to be played in unison by several instruments:
• You can set up a melody to be played in unison by several instruments by creating
several aliases of a regular MIDI region (the melody).
• Different staff styles can be used for each of the different instruments, including
transposing staff styles (for example, Horn in Eb, Alto Sax, and so on).
• If you decide to change something in the melody, you don’t need to edit all copies
(aliases) of it. Just make the change in the parent MIDI region, and the change is reflected
automatically in all aliases.
Editing Aliases
You can directly edit the notes and symbols in an alias if the Allow Alias Editing checkbox
in File > Project Settings > Score > Global is selected.
Note: Changes to aliases alter the data of the original MIDI region (and all aliases created
from it), because only the original region can actually contain MIDI data.
If Allow Alias Editing is turned off and you try to edit an alias, you will be asked to either
enable alias editing or create a copy of the region. Choose the appropriate option, as
follows:
• Cancel: The aliases and original MIDI region are not changed.
• Enable Alias Editing: Alias editing is allowed; remember that this actually edits the parent
MIDI region.
• Create a Copy: A copy of the original MIDI region replaces the selected alias. You can
edit the notes independently of the original MIDI region, as the selected alias is now a
real region.
Changing the Graphical Position of Objects in the Score Editor
You can change the graphical position of objects to improve the layout of your score (by
creating space for a grace note, for example).
