I have a brand new Macbook Pro with El Capitan OS. My interface is a Steinberg UR824. I was a Pro Tools user for about 5 years, but I've decided to switch. I downloaded the trial version of Cubase and Studio One. I've downloaded EZ Drummer, Superior Drummer, and many Waves plugins. All of those are available in Cubase, but none are showing up in Studio One. Is that because I've only downloaded the trial version?
