device_manager_device
It is defined in line 311 of denemo_types.h. It's stored in  
device_manager_midi_device[50] in DenemoPrefs.

You have to have Jack selected as audio output in preferences. Then  
you make sure Jack server is running. Then you will click start/ 
restart Jack under device manager tab. One device and port created  
automatically for you. In staff properties choose the created device  
under the midi tab. Then make sure denemorc is connected to a  
softsynth in qjackctl. To rename ports you can double click on them in  
the tree. They can be renamed but for some reason qjackctl does not  
observe the change. jack_lsp will reflect the change.
