I apologize because I'm a total noob with this stuff... but I can't figure out how to open Helix Native in logic at all. I don't even know where to look for it so I can do any of these other steps. It comes in preferences>plug in manager, but beyond that I can't access it. Is there another piece of software I need to make it work? Or is there something I'm missing in Logic? I've downloaded and reinstalled multiple times. No change.
