Reply to send midi data out with s4?

prior to the s4 i was using an xponent and using osx's built in "audio midi network" utility to send midi data out over a network to a friends computer so i can could trigger video samples on his computer simultaneously while triggering audio samples in traktor on my machine.

i know by default the s4 isn't in a midi mode, but even when i switch to midi mode, i cant seem to send midi data over the network like any other normal midi device. to work around this i am temporarily using a korg nano pad mapped to the sample decks in traktor and this works great. i just want one less piece of gear does anyone know if i can do some configuration in traktor to get the s4 itself to successfully send midi out? thanks and hope this makes sense!
