FabFilter Micro Help
You can easily extend the included presets with new settings to build your own library of presets for FabFilter Micro that you can reuse in various projects. This is also a good way to copy settings across multiple instances of FabFilter Micro in a session.
To save the current setting as a preset, click the preset button, and then click Save As. A standard Save dialog will appear. Type a name for the new preset and click Save to finish.
In the Save dialog, you can also rename and delete existing presets and create a new folder to store presets in. New folders will show up as new categories in the preset menu. (On macOS, this should be done with the Finder.)
See How presets are stored to determine the preset folder location and learn more about factory presets.
