I'd like to say first that I just started with Ardour, and that I am really impressed...
The situation I'm in at the moment is as follows, I have two tracks of acoustic guitar that I want to mix, but there is one note that is not precisely in sync.
So what I want to do is copy the lagging one, and paste it a fraction earlier, and then with some (fast) crossfades, it should come out perfectly in sync.
I think that this should be possible with Ardour, but I couldn't figure out just how to do it. Anyone want to help a total noob?
