I yesterday I purchased the newest Traktor version. I updated the newest firmware for the controller und the newest asio driver.
IT WORKS! The only thing you have too keep an eye on is to restart the controller everytime you restart Traktor. Otherwise all the mappings and functions are messed up.
So as far as i experienced it, you do not neccessarily need an older traktor version. But it is important FIRST to install the driver, then to install the firmware and then install traktor and import the mapping (in thsi order)
Hopefuly this condition will last. If it changes i will post it here!
