I'm at 24GB, about to be 32GB tomorrow if I actually take the time to do it. I started with 16GB, but definitely had some issues. 24GB was nearly enough for my current project, 32GB will do the trick, although I've avoided using my Embertone Walker 1955 with my other patches because I can tell my system won't be able to handle it, probably not even with 32GB. That thing is a resource hog. I'm just settling for rendering audio in a separate project and importing.
