Connection Question

Hey Guys and Gals! Fellow DJ's!

I have a question

My current setup looks like this: photo.jpg

But now i want to go for a similar but different approach Aka my new project!

I want to replicate my setup but with iPads running TouchOSC.

The problem i have run into his how i will go about connecting 4-5 iPads to my computer to run traktor with.

I currently have a Audio 8 behind my setup that is connecting the mixer to traktor if that helps.

Please help me out
