Using the DDJ-S1 with SSL or Traktor?

Has anyone completed or found a midi mapping for the DDJ-S1? I'd like to use my lpd8 for samples and fx controls but ITCH doesnt have midi mapping. Also, I'm interested in trying out vsl.

It seems the jog wheels are where everyone is failing.

Also a question. If I did use SSL or Traktor, would the sound be outputted through my internal soundcard or still through the S1's sound card? (i.e. would I not have headphones then?)

Thanks!
