You can cut or copy regions in the Tracks area, and paste them at a different position. You can also paste a copied region at the same time position, to double the content of the region to use on another track. You can quickly double a region or cut it in half at its existing location.
In Logic Pro, select the region, then choose Edit > Cut (or press Command-X).
In Logic Pro, do one of the following:
Select the region in the Tracks area, then choose Edit > Copy (or press Command-C).
Option-drag the region.
When you copy an audio region, a new region is automatically created in the Project Audio Browser. The new region retains the name of the original, followed by a sequential number. For example, for a region named MyLoop, the first copy is MyLoop.1, the second copy is MyLoop.2, and so on.
In Logic Pro, move the playhead to the point in the Tracks area where you want the region to start, then choose Edit > Paste (or press Command-V).
In Logic Pro, select the track you want to paste the region into, then choose Edit > Paste at Original Position (or use the corresponding key command).
The copied region is pasted into the selected track, at the same position as the source region. This is useful if you want to copy a region to the same spot on a different track, to independently process or thicken the part, for example. This function is also ideal for creating layered MIDI or instrument parts.
In Logic Pro, select the region.
Choose Edit > Repeat Multiple from the Tracks area menu bar.
In the Repeat Regions dialog, do any of the following:
Enter the number of copies to paste in the Number of Copies field.
To have the copies snap to a particular grid value, choose a grid value from the Adjustment pop-up menu.
To paste the copies as regions, click the As Copies radio button.
To paste the copies as aliases for MIDI regions, click the As Aliases radio button.
When you cut a region in half, the region is cut at its center and the right half is discarded, leaving only the left half.
In Logic Pro, select the region, then choose Edit > Length > Halve.
When you double a region, its length is doubled and the contents are repeated in the right half.
In Logic Pro, select the region, then choose Edit > Length > Double.
You can change the length of a region, cell, or event by an exact amount.
In Logic Pro, select the region, then choose Edit > Length > Change.
Choose the amount to shorten or lengthen the region from the Length Factor pop-up menu, then click OK.
The Length Factor pop-up menu includes a variety of set values, ranging from 0.25 to 16.
