Logic Pro AI session musicians - Where were they sourced from?

Hey, I was just wondering what data the AI was trained on. How many musicians, and who. I'm wondering how limited the AI's possible generative ideas are, especially if the sources are homogenous - e.g everyones from North America (where many of Apple's studios are), and only a few are from their bases in e.g Tokyo. If the AI has world influences, it could become more creative.
