I always see loads of preset packs on the sister site so I presume there is some kind of demand, but I can't imagine people really paying for them (especially since a lot of the preset packs sound pretty rubbish).
I have loads of presets I've made for various projects, plus I quite enjoy pushing synths to see where they sound best, so I figured I might try to put one out myself if it's not a waste of time.

 

I no longer buy presets and have been making my own presets since 2011.
