FX PRESETS - Unit Presets
An FX Unit Preset consists of the complete customized parameter settings of a specific FX Unit, which allows for “total recall” of that one effect. It's very useful to build a library of FX Unit presets that you like, since you can quickly experiment with trying Presets that were created for one purpose, but using them for a completely different purpose.
FX Unit Presets are organized so that only Presets relevant to a particular unit appear in the Preset List. For example, in the picture below, the Retroplex Delay has it's own Preset list.
This makes working with FX Presets very easy and clear. You will only see the Presets that pertain to the FX Unit you're working with.
Patches are saved in the Omnisphere/Settings Library/Presets/Effects/ directory.
You can create as many sub-directories for patches as you like, as long as the folders are nested in the specific directory for that unit on your drive. FX Patches have the extension .fxp_rmx
