soo i downloaded a demo version of traktor pro and it has an actual crossfader but the bar that slides back and forth isnt there and no matter what i do in the settings i cant figure out how to get it to show up. ive tried looking for some keygen sites but even with a mac im not really sure i want to download from some of those sites. i was wondering if anyone had a key or knew where a semi-legit keygen can be found
