Reply to problems mapping numark total control with traktor

Hi everyone I am having some problems mapping my numark total control to traktor!

My DJ setup is as follows... numark total control and dj/io (sound card) attached to my computer (ps I know it sucks but i had to start somewhere)

1st When I had virtual dj i could control how long the loop was by pressing two buttons right above the loop in and out! I can not seem to find this control with traktor ( there were 4 buttons total and they either shortened or made the loop longer) I would like to set this up with traktor!

2nd problem ( i want to be able to play 4 things at once . when I switch to 4D Int. Mixer it changes the settings around so i have no crossfader! i want a crossfadder to control the two top decks and the bottom two decks I only want my two jog wheels to control the bottom. for play and pause on the bottom I wanted it to be mapped out to the keyboard) basically I obviously dont want a crossfadder on the bottom I just want to be able to play random sounds using the bottom decks
Can anyone tell me how to do this or give me advice!
Thanks so much any info will be greatly apritiated
