On his website, you can find free sounds * for Sytrus and Pro-53
Under "Sounds" he has made even more presets for Vanguard, V-Station, FM7, Z3ta+, Sylenth1, Zebra 2, and Massive.
* Update: The website went through an overhaul and I don't know if those sounds are available any longer but, there are a lot of new sounds there for you at a reasonable price so check them out!
Not only does he design his own presets but he produces too under his pseudonym "X-Plorations" and under his real name.
