Some Sonnox plug-ins (Reverb, Limiter, SuprEsser and Envolution) include factory presets, because we feel that you will find these useful starting points.
However, the original design team felt that presets for other plug-ins were inappropriate, given the wide range of programme material being processed.
The Oxford EQ, Dynamics, Inflator and TransMod don't include factory presets as such, only a few with EQ and Dynamics to describe some of the basic operation modes, eg. EQ curves.
We have been considering an area of the Sonnox website where users can share presets.
