Hi, trialing Traktor pro after endless frustrations with other softwares Midi Mapping options, after a rocky start due to a very strange bug in Traktor install ( play wouldnt work properly, had to delete application support files and reinstall to fix ) was finally able to get traktor pro 3 installed, however none of my midi mappings seem to be able to do anything . this is problematic for me as the only way I can know if Traktor is adequate to my needs is by testing the midi mapping functionality as that is where every other DJ software on the market has let me down so far. if this is an intended limitation, please make that clear in the options, and if it is not please fix so that users can test midi mappings in the demo
