Can Cubase do this and I'm missing it?

You mean an alias version of Ctrl-D? No, there isn’t. The best you can do is Ctrl-K where you can set up multiple copies, shared or not. It’s not as slick as what you’re looking for but better than nothing. I think it would be a good request, though. I’d vote for it.

You do mean Part, don’t you, and not Event? No, audio parts auto-size to the extent of the audio events they are created from. MIDI parts and audio events can be drawn to a snap value but I don’t think that’s what you’re talking about, is it?

And yes, make your case in the FR forum.

Hope that helps,
