As the title says. Is this possible?
The FMOD for Unity plugin comes with a Find and Replace tool, which you can access via FMOD → Find and Replace. Using this will allow you to search for events by name and find all Studio EventEmitters in a scene that make use of the event.
Note that this feature was unfortunately bugged before 2.01.23/2.02.14 - if you’re using an earlier version of the plugin, you’ll need to update to one of those versions or higher.
