Reply to How do you achieve these build-ups?

For a while I've been playing with a Pioneer DDJ-T1 and Traktor, but a few months ago I started with CDJ1000's and a DJM600 mixer as well as I find it important to be able to DJ on all major options. Beatmatching and timing is going better progressively, and playing two tracks that build up or drop at the same time is nice. With the DJM600 using the Echo effect at 1 makes a nice sound during the build-up as well. But something I have never managed to figure out is how some DJ's get these incredible build-ups. Is there someone who can help me out with this?

Some examples:

Ladi Dadi - Tommy Trash instrumental mix, the build-up is longer and sounds different than the normal one. How does he do it or is it a home-mode edit?

Firebeatz - Here we go, same thing, the build-up with loads more of drama. Any explanation is very welcome!

Sorry for it only being Hardwell build-up's, however, many DJ's manage to add the same amount of drama to build-up's like these as well. I'm really curious as to how they do it and I can't find the specifics so I'm just hoping someone can explain it (partially) to me. I'm just trying to improve my own game. My apologies for this being my first post here, have been visiting for a while now and without this site I probably wouldn't even be able to turn on, let alone work with dj-gear
