Logic’s Music XML feature only does export, not import, which makes sense – you’re likely not bringing music into Logic to clean up the notation. You can import .smf from Sibelius or Finale for file transfers if needed.
To access the Export feature, you need to have the Score Editor open and then go the main File Menu>Export>Score as MusicXML. This will be greyed out if a Score Editor window is not open.
The score display is what is exported – make sure you have the correct tracks and number of tracks displayed. With that in mind you could do a score set of e.g., just strings and export those.
Once exported you’ll find the file with a .xml ending. If you just click to open you’ll likely not get it opened in a notation program – you can import / open via Finale / Sibelius or select one of them to open the file.
What it does better than a Standard MIDI File:
Notes come in more faithful to the Score Editor display regarding note duration and placement. See my article on Logic 9 for reference on how the Score Editor display does length and duration quantization. There doesn’t seem to be the certain need to go through the steps mentioned in that article, although it can’t hurt.
It will bring in articulation and phrasing marks (.smf doesn’t).
What it doesn’t do:
No chord symbols.
Properly place region start if not on 18.104.22.168. If your first region on a track is not at 22.214.171.124, that’s where the XML export file puts it, and all ensuing regions move forward in time an equal amount. You need to have the first region of every track start on 126.96.36.199. You can drag the region’s leading edge to the left, or, if needed, create an empty MIDI region at 188.8.131.52 (this region name will be your part name, see below). Then you will get rests where appropriate (areas of no regions and/or empty bars) and music starting at the correct measure.
Part names are based on Logic’s region names, not track names. The first region name of a track determines the part name.
I’d recommend quantizing notes before you add phrasing marks, certainly so if you use Logic’s key commands to add them. Their placement is based on note selection and therefore the position of the note. I’ve had them come in one note late when importing in my notation program of choice because I didn’t quantize.
Go into the Score Set window and correctly set the bar lines in the score. Logic defaults to having the bar lines run through all parts, generally not what you want. It can be fixed in Finale and Sibelius, but doing it here saves a step later.
