It's something i've been hearing a lot lately.. They beatmatch and phrase match two songs, when Song A is about to hit the breakdown they cut it to Song B, so you get song B's breakdown, but then on the buildup they start adding lots of effects and shit and they eventually go back to Song A but because of all the effects on top of the songs you don't really notice until song A drops again.
It's the effects and the EQ'ing i wanna know about..it's not like super colorful effects that bring the audio all the way up..and that's what i don't get..
I know they use pioneer equipment, and pioneer's effects are different than traktor's but it shouldn't be that much different.
You can hear an example here:
