The MIDI file specifies a port number, which ist just a number from 0 to N-1; it's the player's responsibility to map this to actual ports. Because of this unpredictable mapping, the MMA has declared the port number meta-event obsolete. Officially, one should now use the port name meta event <FF 09 len text>, but the mapping of the MIDI file's port names to the playback device's port names does not happen to be any less unpredictable ...
