Midi-Ox? I think that is a program to replace midi codes by other midi codes. It sits between your MIDI in/output and Traktor. For example, Traktor cannot do anything with "Program Change" codes; only note codes and "Control Change" (CC) are usable. So "Program Change" has to be replaced by one of the above to be usable in Traktor.

That said: I've never been able to get the non-free Midi-Ox or one of the other similar programs to work.

BTW this looks like a reasonable page explaining what kinds of MIDI messages there are.
