3. What Is A Rhythm Jogger?  The Rhythm Jogger's main purpose is to keep track of a user's jogging pace and play midi songs at the proper speed to give a more enjoyable jogging experience.  No pitch change requirement –Use Midi (for simplicity) –Very high quality music still possible  Both tempo and phase matching important
