From what I have seen in the different Cubase 14 Operation Manual versions, it seems that only the Pro and Artist ones have the Event Volume Curves feature implemented.
More or less, yes, but from what I have seen, the difference is that the overall volume clip in Elements is only controlled with the new event volume fader, reachable on the bottom left of it. Pro and Artist have the added Event Volume Curve, usable with the Draw tool.
