Logic Pro supports the Euphonix “Open plug-ins on workstation when editing” and “Close plug-ins on workstation when exiting” preferences.
If the Link button is enabled in an open plug-in window:
“Open plug-ins on workstation when editing” does not open a new window when a new plug-in is selected, but replaces the open window’s contents.
“Close plug-ins on workstation when exiting” does nothing.
If the Link button is disabled in an open plug-in window:
“Open plug-ins on workstation when editing” opens a new plug-in window.
“Close plug-ins on workstation when exiting” closes the plug-in window.
