Reply to Using X1 on Live Performance

Hey all, i hope its the right community s for that kind of question but im quite lost

im using Traktor Scratch Pro 2 on a Macbook Pro and im gonna perform live very soon just uncertain about stuff atm...i was using Timecode CDs this whole time with an Audio 4 DJ , external mixer and 2 CDJs...now i found the timecode CDs un reliable...yet, iv seen so many DJs using 2 X1 Controllers , External mixer and a Laptop with an Audio interface...

i have alot of questions of if is it possible to use 2 X1 Controllers instead of a pair of Turntables and how its being done? i.e how to Control tempo or Search between tracks? what are the advantages and disadvantages of using that stuff?

I know its possible because iv seen DJs using X1s a Laptop , audio interface and wont even use the CDJs at all their whole performance...i hope im clear, im just confused!

Thanks alot
