The elysia preset package contains files in the .tfx, .aupreset, .fxp, .vstpreset formats. They can be used with Pro Tools, Logic and other AU compatible hosts, and Cubase as well as other VST and VST3 compatible hosts on Mac OS or Microsoft Windows based machines.
All you need to do is locate the correct file format for your host and copy the preset files into the corresponding folders on your machine. If you have not saved any presets with the plugins before, you should do so in order to create the preset folders automatically. Some hosts alternatively offer to import preset settings directly from the plugin user interface (like the “Import FXP/FXB” function in Cubase).
