Chapter 4 Editing Regions 41
Loops
The Loop function enables you to repeat a Region automatically, without needing to
copy it. The Loop switch can be found in the Region Parameter box.
In the Tutorial song, you can see a looped MIDI Region on the ES1-2 track, between
measures 13 and 17. The loops are displayed as gray segments, following the original
MIDI Region. These loop repetitions are always the same length as the original MIDI
Region.
To switch off looping:
1 Select the original MIDI Region.
2 Click the On option, found beside the Loop entry in the Region Parameter box. The gray
loop repetitions disappear.
3 Reactivate the loop by clicking beside the Loop entry again.
4 Click on the bright blue “Kick” MIDI Region that follows the loop repetitions, and press
the Backspace key. The gap is immediately filled with further repetitions of the original
MIDI Region.
Note: A looped Region is repeated until it encounters another Region on the same
track (or the song ends). To turn off the repetitions at a desired position, simply insert
an empty Region onto the track with the Pencil tool (or by copy/pasting another blank
Region). In the following, we will use the term Stop Region to refer to this kind of
Region.
To increase the length of a loop:
m Grab the lower right corner of the original MIDI Region, and drag to the right to
increase its length by one bar. As you can see, the loop repetitions change their length
accordingly. This can be done while Logic is running, allowing you to immediately
listen to the results in the context of the arrangement.
