Managing System Components in the System Component Information Window
To make a plug-in available for selection, activate the checkbox in the left column.
Only the activated plug-ins appear in the effect selectors.
To see where a plug-in is used, click in the Instances column.
NoteA plug-in may be in use even if it is not activated in the left column. The left column only determines whether or not the plug-in is visible on the effect selectors.
