MacTron ,

My mistake, Apple Midi Manager was parked in the wrong place in System folder.  I finally realized that  when I launched Ballade and it did not show signing into Apple Midi Manager. For some unknown reason I thought it should be in the Extension folder with Midi Manager. Another clue i missed was when I launched Apple Patch Bay there were no virtual midi cables between Ballade and Apple Midi Manager. Whereas if the Apple Midi Manager and Midi Manager are placed correctly Ballade will make the correct corrections.  Now we hear music. Thank you for your subtle clue.
