<< Is there a way to automatically generate all tracks in a song with a freshly selected style as soon as the StylePicker is closed by pressing the OK Button? >>

Try this:

From the StyleMaker - highlight a style and use the play using current Chord Chart Song button.
When the song begins to play, hit the StyleMaker OK button and the screen switches to the Chord Sheet Main screen without any interruption of the song playing the selected Style. There's no regeneration. The selected style is loaded onto the current chord sheet of the song and plays at the correct tempo and key signature.
