Mike,
The styles used in the Registrations link to the Presets.
But have you looked for styles directly in the Superior Pack folder within the Expansion folder?
Those styles do not have Genos Preset names although not having explored them in much detail I can't vouch for how differently they sound from existing ones. I feel there are some useful ones in there worth spending extra time on, (and I don't normally feel that way about Yamaha's efforts outside of the keyboard presets) .
Plenty of EDM and Schlager/ Alpen if you like it
