I started MSE 6.3.1.1 with the stock OSX Music sample and viewed/worked with the mixing board.
Then I closed it out and imported a unrelated midi file.
When I opened up the mixing board I thought it would be the set to go for the new midi file.
The mixing board still showed all the tracks etc for the previous project ( BlueThing Using DLS ).
No doubt I am doing something wrong somewhere because I could not get the mixing board to refresh.
At this time I would also like to ask how can I make the mixing board show just the current tracks in the project. If I need a track I should be able to include it in the mixing board. I generely build a song one track at a time so I don't need the board showing me, let say, 24 non existing tracks. Here again I more then am not setting my board up correctly.
