Are you talking about multiple ‘takes’ on the same audio track/lane? Or are you talking about effects?
If it’s multiple takes you’re referring to - as it seems at least in your thread title - I believe this began with Cubase SX…I can’t recall exactly, but it’s something on the transport bar that allows you to do this, I think on the left side there’s a ‘stack’ ‘mix’ ‘combine’ modes, etc…which as I recall is for midi or audio, to allow you to have the multiple waves on an audio track…or multiple midi bars on a midi track.
If it’s something else you’re talking about, I don’t have a clue.
As far as printing effects, not sure about all versions, but I do know VST 5 gives you the option of printing effects or not when you export in that dialog box. I’m sure that all versions must have this option ‘as you export’.
