Hiding and Showing Extended Parameters
Some Logic Pro plug-ins may have additional parameters that don’t appear in the Editor
view (the graphical interface of the plug-in).
This is indicated by a disclosure triangle that appears at the bottom-left corner of the
plug-in window.
If no disclosure triangle is visible, the plug-in has no additional parameters.
To hide or reveal the extended parameters
µ
Click the disclosure triangle at the bottom of the plug-in window.
