Regardless of the version you are using,
here are the steps to follow to use the plug-ins within Analog Laboratory.
- Enable the plug-ins in the preference panel (PREFS button in the toolbar)
- Restart Analog Laboratory
- Select Sound Mode
- Select a preset
- Click EDIT
- The button OPEN should now be enabled, unlike when the plug-in was not enabled
- Click OPEN
-> The plug-in should open.
Hope this helps
