Apple Logic Express 8 - Manual (Page 264)

264 Chapter 10 Working With Instruments and Effects
Important: The first thing you should do is check the manufacturer’s website for
updated versions of Audio Units plug-ins that fail validation.
Manually Enabling Plug-ins
Audio Units plug-ins that failed the validation test, can be manually enabled by
activating the checkboxes in the Logic column—but be aware that these plug-ins can
cause problems.
If you encounter problems with manually activated failed plug-ins, click the Disable
Failed Audio Units button.
Disabling Plug-ins
The Audio Units Manager also allows you to disable Audio Units plug-ins that you don’t
want to use in Logic Express, even if they pass the validation scan. Simply uncheck the
corresponding checkbox in the Logic to disable any plug-in. You can store your choice
of Audio Units plug-ins by clicking the Done button.
Click the Reset & Rescan Selection button to rescan a selection of plug-ins, after
installing plug-ins/updaters or moving components in the Finder, while Logic Express
or the Audio Units Manager are open. They will be enabled automatically, if they pass
the validation scan.
Note: If you press Control-Shift while opening Logic Express, the Audio Units Safe
mode will be used: Only plug-ins that pass the validation test will be available;
manually activated plug-ins that failed the validation test will not be available.
Warning: Use of plug-ins that have failed the validation can negatively affect the test
results of subsequently scanned plug-ins. They can also prevent Logic Express from
launching, cause it to quit unexpectedly, or even lead to data loss (destroyed project
files)!
