The MIDI samples were a really poor choice to introduce the program's compositions, but those snippets do sound a lot like Bach chorales stylistically, perhaps at the level a competent (if uninspiring) student of harmony.

The chorales exist online in machine-readable formats at http://www.jsbchorales.net/ (a great resource for doing comprehensive analysis on chorale harmony -- wouldn't doubt if the same data served as input for the Emmy program).
