MIDI is NOT RS232. Electrically speaking MIDI is a current-loop, basically you are driving an LED in an Optoisolator. You might be able to get it to work with an RS232 port, I don't know I have not tried, but I doubt it would be reliable. For more information on MIDI protocols try the MIDI manufacturers association. http://www.midi.org/techspecs/midispec.php
As for finding an AXB-MIDI, they show up on Ebay periodically. There was also a thread about using an RS232 to MIDI converter recently.
I've actually gotten it to work. This was with an old AXB-232 box. It may well not work on an NI's serial port. I knew the baud rate was different but it worked for some reason. As for the opto-coupling. I think I got away with it due to my cable being less than 6". Here again the AXB might have been a factor.

MIDI is nothing more than good old rs232. The baud rate is 38400. You can google the protocol. It's hex but it's not bad.

I haven't used these, but they might be an option: http://www.kissbox.nl/products_new.html#midi
