Logic Pro and Logic Express 7.1: Loop Type options may be unavailable when adding regions to the Loop Library

Logic 7.1 allows you to add audio regions from audio tracks or MIDI regions from audio instrument tracks to your Loop Library. To do this, highlight the region you wish to add, and then from the Arrange window's menu bar, choose Region > Add to Apple Loops Library.

A dialog appears, allowing you to set the tags for the loop. You can set the loop Type by selecting either the Loop radio button (the loop will conform to the tempo of the song) or the One-shot radio button (the loop will maintain a fixed duration, ignoring the song tempo).

However, sometimes these radio buttons may appear dimmed, with the Type set to One-shot.

This can happen if the selected region is not precisely trimmed to contain a number of whole bars. Only regions that are set to whole bar lengths will give you the option of selecting the loop type (either Loop or One-shot); all others can only be added as a One-shot. There are several ways to work around the issue:

• Trim the region so that its length spans a number of whole bars at the current song tempo.
• Change the tempo of the song to conform to the region.
• Add the loop using the Apple Loop Utility application. You can do this from within Logic; just highlight the region and, from the Arrange window's menu bar, choose Audio > Open in Apple Loops Utility.

  

Apple Loops Utility allows you to define the intended length of the loop, regardless of the song tempo. Please note that the utility only works with audio regions—not with MIDI regions on Audio Instrument tracks.
