Hi all,
This is my first post and I’m a Cubase newbie having just bought Cubase 6.5 and using it on Windows.
I’ve a few scores in MusicXML format. I mainly use Kontakt within my DAW as a host for orchestral samples to create mockups. How do I use the MusicXML score file I have?
Sorry for such a newbie question!! 
Hi, and welcome in the forum!
You can import and export MusicXML files into/from the Cubase.
You can find more information in the Operation manual on the 660 page. There is list of events, which are imported, and which are exported, same as description of process, how to import/export MusicXML files. There are 3 pages only, so it’s quite short. 
Good luck with your new Cubase!
