I'm trying to learn my synths a little better, and am practicing creating SFZ files for Rapture Pro. I'm following along with the book, "Cakewalk Synthesizers" by Simon Cann, which I know has been around a few years, so maybe some info is outdated. That being said, as a person attempting to create an SFZ file for the first time, to be used in Rapture Pro, which version of SFZ should I be looking at, version 1 or version 2?
