Apple Logic Pro 9 - Manual (Page 282)

When the Link Button Is Switched Off
You can open several plug-in windows simultaneously, and these do not update to reflect
any track or plug-in choices you may make. Each open plug-in window does, of course,
continue to show all parameter updates and changes.
Turning Link off is handy when you want to compare the settings of two plug-ins, or
adjust the parameters of several open plug-in windows at the same time.
Bypassing Plug-ins
If you want to deactivate a plug-in, but don’t want to delete it or remove it from a channel
strip, you can bypass it. Bypassed plug-ins do not drain system resources.
To bypass a plug-in
Do one of the following:
µ
Click the Bypass button at the left side of the plug-in window header.
µ
Option-click the appropriate Insert or Instrument slot on the channel strip.
The Insert slot of the bypassed plug-in turns from blue to gray, indicating that the plug-in
is currently bypassed.
Getting to Know the Settings Area
All current plug-in parameter settings are stored with the project file, and are automatically
recalled the next time it is loaded. You can also save and recall any changes you make
to plug-in parameters. These are stored and recalled as individual settings (or presets, if
you prefer) via the Settings area.
