Create aliases of MIDI regions in the Tracks area
You can create an alias for a MIDI region or a folder. An alias is a reference to a region, and looks
similar to a normal region in the Tracks area. If you alter the original region, all aliases of the
region are similarly altered.
Aliases can be useful when you want to repeat a phrase or riff in different parts of an
arrangement. If you make changes to the original region after creating aliases from it, the
changes apply to all its aliases throughout the project. If you want to edit one of the aliases
without changing the others, you can turn that alias into an independent region (a region copy)
and edit it independently.
Aliases do have some differences from their “parent” region: you can give each alias its own
name, and edit region parameters for each alias independently.
Alias names appear in italics to distinguish them from normal regions. If you name an alias, its
parent region name is shown below the alias name (provided that the zoom level is adequate).
Any changes made to the parent region name appear on all its aliases.
Create an alias
Do one of the following:
m Option-Shift-drag the region to the position where you want the alias to start.
m Select the track you want to create the alias on, position the playhead, select the region you
want to create an alias from, then choose Functions > Region Alias > Make Alias (or use the Make
Alias key command).
You can also use the Repeat Regions command.
If several regions are selected, their relative time and track positions are retained. The selected
track is the destination track for the first region along the Tracks area.
Reassign an alias
You can assign a new original region to an existing alias. This is exceptionally handy for arranging
tasks where the structure is right, but the part is wrong. You can copy a region to a new track,
create an alias, mute the existing region, and click Play, or use the far simpler method below:
1 Select both the alias and the intended new original region.
2 Choose Functions > Region Alias > Re-Assign Alias (or use the Reassign Alias key command).
Search for an original region or alias
If you forget where the original is for a certain alias, you can search for it. Do one of the following:
m Select the alias, then choose MIDI > Alias > Select Original (or use the Find Original of Alias key
command).
m Choose Functions > Region Alias > Select Aliases of Region.
