Sure. Go ahead. I have to work most of the day and will have little  
time later. When I have time what should I try to fix next? I noticed  
some music games are not working fo some reason. I will need to fix  
that before release.

We also need to create the device/ports in Jack. When they are created  
in Jack they are supposed to appear in the gtktree. This was my  
intention. If device or port is not able to be created then it returns  
-1. If -1 is returned nothing is added to the gtktree. I have not  
thought out the case if Jack was not initiized and the prefs load up  
before Jack gets initialized. I suppose this would be a case for  
putting the port name list in the denemo file. Then when users launch  
denemo with "last file" or pass filename at command line, Jack will  
not be initialized. So we need to store the port name  lists somewhere  
and or initialize Jack on startup if Jack server is running. I am not  
sure how to do that exactly. I can attempt to initialize Jack  
(different from launching Jack server) at startup. If it fails it  
fails. We will probably want to display a message or have the device  
tree be empty if that is the case.
