It's very funky but I have no control at certain moment on this player.
I create rythm part(Style Phrases) then copy it to double, it won't play the same chords position and to ramdomly

 

I can't help you with Macintosh, but in Windows works well, I'm using it right now

 

It's more a problem with the articulations option. some licks (Style Phrases) are more regular if the command is integrate in the note's parameters ( only Logic

), sometimes it's better the classic way key changing.
