It's not clear what you are asking here - what kind of array do you mean? But if you are trying to write a program to create a score, the supported way to do that would be to simply write a MusicXML file - that spec is public, and MuseScore can import files in that format.
If you need further assistance, best to ask on the forum where tons of people will see it, not here in the issue tracker.where it won't really be seen at all unless it's a bug report.
