Reply to Need help setting up my modular set up with Traktor

Hello DjTechtools, so after months of researching about djing and djing gear I finally took the plunge and bought the pieces for my modular set up. Picked up all my gear used as I'm on a budget.

My gear:

• KORG KM-402 4 channel mixer (to mix everything down)
• NI Kontrol X1 (for decks A and B transport control)
• Native Instruments Maschine (because I've started with producing and believe it would be fun to incorporate some simple live playing in)
• Traktor Pro 2 Software

So question!: Notice, I do not have a soundcard!! I am asking is there any specific soundcard I need? Or since I'm using Traktor I have to get NI soundcard? Also when I do have this soundcard, how would I set it up so that I can use the internal decks via Traktor Kontrol X1 and mix externally via Korg KM-402. Also how to fit the Maschine in with all of this?

I have done a lot of research but googling how to use external mixer with internal decks has only led me to how to operate timecode, which is not part of my question.

All tips or walkthroughs for how to get my set up, well set up would be so appreciated as I can't wait to finally just get down to playing on all this gear I've worked had to select and gather!

Sidenote: The NI Maschine I bought used on this community , I was just finally able to try and both of the LCD screens are showing very bright with almost no contrast making them not readable unless you're eyes are right at them, does anyone know what this problem may be?
