That was my assumption as well. I could pick many things in science-fiction apart until I’m blue in the face, but most things end up falling under the “it just does” category!
I was also thinking the same thing as far as Time Lord tech goes, that the Tardis, being as smart as she is, could find a way to interact with the new sonic. The Doctor would also be smart enough to build in some kind of interface to help the Tardis out.
