Seemingly out of the blue the xfade function stopped working.
Deleting the preferences, safe mode, modifying the UsePreferences.xml, nothing worked.
Then I saw that on the popup xfade window, the range was set to 0.0 for some reason, and that seemed to have become the default value. All I had to do is to change that value to something greater than 0.0
TBH, if you select the overlapping part of two events, it doesn’t matter what are the length settings, the overlap is the length. And if no overlap, then no cross-fade.
You are missing my point. Xfade would not work at all, overlapping or not.
On your screenshot, the cross-fade editor is empty…nothing selected, no length.
I was actually trying to reply to an older thread where many people had the exact same problem, but somehow a new thread got opened.
I can’t link it here, just Google:
Cubase 11 Crossfade greyed out.
Maybe that will give you a better understanding of what I am talking about
Oh, yes I know that thread. It’s closed now. And I contributed to it.
To sum it up, it wasn’t entirely clear that it was a bug or something similar.
At the end, we could not reproduce the issue.
What I usually do: I have the settings on “delete overlap” , i pull 2 audio files together to where i need them to be, then hit “x” to crossfade with a default setting. they don’t have to overlap in order for the crossfade to work.
In my case the other day I would hit “x” and nothing happens. then i click on the audio file, and the xfade menu opens, as shown above. What I can’t actually recreate is the value just being empty, not even showing 0.0. which is what happened.
thinking of it, I actually don’t know how that xfade menu opened, since it was also giving me an error message saying that there is nothing to be crossfaded.
Anyway, after I manually change the xfade range in that menu, everything is back to normal.
I hope that was not too confusing
The reason I was posting this is because non of the suggested fixes in the thread mentioned above worked for me.

Cross-fades working on overlaps only. Otherwise, it’s a fade in and a fade out.
That’s wrong, as already stated.
Well, I challenge you to do the following:
Take 2 audio events, line them up back to back, not overlapping but touching , select both and hit X.
Let me know what happens
