On your software, in the presets>my preset tab, you will find the presets you have saved. To the right of the name you have given to your preset is an icon with an arrow, by pressing this arrow you will be able to export the selected preset to the location of your choice.
Once saved (file with the extension “yourpresetname.xml”) you can send this file to your friends, which they can load from the “import preset” section of the presets window.
