Unless you have the Studio One Professional version I don’t think you can. See https://www.presonus.com/products/Studio-One/compare-versions

I went off about this last week. I could not believe the Presonus will not let you use VSTs you own. And when you say something about this they most likely get upset.

If you have the Artist version you can pay about $100 or so to get an upgrade that allows one to use VSTs. IMHO that stinks.
