How do you call up Audio Effects in FCPX?

Lets say I have adjusted a piece of audio and I want to then copy that or use that template that I have saved - where are they?

I know how to use the save effects button, but I can't find where the effects or presets I have made are when I want to apply them to a new clip???

When you click the Save Effects Preset button, you're presented to give your custom preset a name, and assign it a category.

To find it, go to the Effects Browser, to that Category, in either the upper Video section or the lower Audio section, depending on which type you created.
