Display and edit aliases in the Score Editor
You can use alias regions to mirror existing MIDI regions or folders at different positions in the score. An alias points to the original MIDI region or folder from which it was made. For information about using aliases, see Create aliases of MIDI regions in the Tracks area.
Aliases are displayed in the Score Editor, and when you print the score. You can assign a staff style to an alias different from the one assigned to the original region—for example, if you double a unison melody on several instruments with different transpositions (such as a saxophone or brass choir). (For information on staff styles, see Staff styles overview.)
You can allow direct editing of the notes and symbols in an alias. Editing an alias changes the original MIDI region (and all aliases created from it). If Allow Alias Editing is turned off and you try to edit an alias, a dialog appears, asking if you want to either enable editing of aliases or create a copy of the region. If you choose to create a copy, you can edit the notes independently of the original MIDI region.
