Might be OK, but

trying to open an original native instruments mapping file (Maschine.tsi) from ver. 2.6.5 leads to the following message:

"Few of the mappings contained in the file have not been loaded because they are not supported in the selected Traktor version or contain invalid settings. Saving the file will result in a permanent deletion of these mappings.“

I think there have things to be reworked. especially because you can´t tell which mappings will be discarded.
Hope there will be an update soon.
