To reconfigure the memory
µ
Click the Reorganize Memory button in the Project Information window.
At the same time, the current project is checked for any signs of damage, structural
problems, and unused blocks.
If any unused blocks are found—which normally shouldn’t happen—you will be able to
remove these, and repair the project.
Note: This reorganization is also carried out automatically after saving or loading a project.
A common (and good) use of this feature is to free up memory after closing a project, if
two or more projects were open prior to the close operation.
Setting Project Properties
Following the creation of a project, a number of project properties should be checked,
and changed if necessary. This is a great working practice as it will limit any morning-after
corrections that will need to be made later, such as sample rate conversions on a hundred
or more audio files. This section outlines the project properties that you should take into
consideration before beginning any work.
Setting the Sample Rate
The project’s sample rate determines the number of samples Logic Pro uses for audio
playback. When you add or record audio files to your project, the sample rate of these
files is automatically matched to the project sample rate.
Important: The “Convert audio file sample rate when importing” project setting must be
active for automatic sample rate matching. You can turn on this setting in the File >
Projects Settings > Assets pane.
To set the project sample rate
Do one of the following:
µ
Choose File > Project Settings > Audio (or use the Open Audio Project Settings key
command), then choose the a sample rate from the Sample Rate menu.
