3 Choose Region > Cut/Insert Time > Snip: Repeat Section Between Locators (or use the
corresponding key command).
The portions of all regions that are wholly, or partially, encompassed by the locators
will be copied, and pasted to the right locator position.
Repeating Regions
Logic Pro provides a number of ways to repeat a region, through use of loops, aliases,
and clones. These options make arranging faster and simpler.
Using MIDI Region Aliases
An alias in Logic Pro is like an alias in the Finder. It looks like a region, but contains no
actual data. It is just a reference to the data of the original region—a virtual reflection
of the original.
The Relationship Between Parent and Alias Regions
If the data in the original region is altered, this immediately affects all aliases of the
region. As examples of how aliases can be used:
 If a riff or phrase reoccurs throughout an arrangement, it’s quicker to use aliases,
rather than creating copies of the original region.
 If a part is not quite right, you only need to alter the original, and the correction will
automatically take effect throughout the whole arrangement.
If, however, you want to alter a detail at one point in the arrangement (a pitch shifted
verse, for example), you can turn that particular alias into an independent region (a
region copy).
Aliases do have a level of independence from their parent region:
 Aliases have their own set of region parameters.
