For me, the onboard styles provided with the keyboard are more than enough... if you spend some time to tweak and change some things in them, add, take away, re-voice and so on. I know many users prefer to use something existent already - why waste time creating something new? - but for many other users that's the whole point: to create or re-create something of their own and use it in their performances.
Me, being a minimalist in aproach, I think we're trapped quite often in Acquisition Syndrome... Styles, sounds, vsts, vstis, DAWs, gear... In fact, today's equipment, even in the basic form is most of the times enough - just the personal abilities must become better.
44.000 tousands styles?!?!?!

I understand the wish of getting all that is available (?!) but in real, do we ever use more than 200-300?
Blessings,
