Reply to Traktor Kontrol F1 and some other basic questions

Hello DJTT! I'm new to the community s and even DJing as a whole. I recently got into finger drumming when I saw a video of Mad Zach and some guy playing with MIDI Fighters. After a LONG debate on a MIDI Fighter Spectra or a Traktor Kontrol F1, I chose the F1. So far, I love it, but one thing is bothering me beyond means: I can only control one column of a remix deck at a time on the Traktor Pro software. This led me to try out Ableton. Now my problem with Ableton is that after several hours of mapping/guides/etc, there's a delay in my button presses and my audio clips tend to loop unnecessarily. My latency is at 15ms so I don't THINK that it's bad. Can some one tell me what I have to do to just finger drum? I want to be able to use ALL my buttons at once without buttons from another column cutting out, that's all. I don't see myself doing heavy DJing and I just want software/options/configurations to achieve this. So far it's been a bigger hassle than a pleasure /:
