Different Voice for Melody in Theory Course Examples?

New user/student. Maybe the audio examples could be updated so that melodies are in a different voice(instrument) that the harmony (chords). In several examples, especially on strong beats, using the same piano sound makes it a little difficult to hear the melody distinctly. Little nit pick–the material and the way it is presented are excellent. Much better that my college music theory one course and instructor–haha.

Thanks!
