I just did a quick test that relates to the "port" meta-event using 
Cakewalk Professional 3.01 (1994).  I would hope its the same on 
Sonar. 

I saved a multi port sequence as a smf.  Then I loaded the file back. 
The port assignments were intact.

E-Loader's file viewer confirms a port event for each track.  I 
haven't yet tried sending the file to the E-Mu and then getting it 
back.

Track 0 event has the port events for the sysex banks.

Hope this helps.
