a2jmidid shows correct names in a form such as:

'rosegarden [129] (capture): out 1 - General Midi'

Aj2midid does react to deleting and creating a new MIDI out port (i.e. 
'device' but if you create one when it has already been started it won't 
ever pick up the correct name. On the other hand if you load a 
rosegarden file which already contains multiple midi out devices with 
different names it will indeed pick them.

Best,
