Question about Sound of stereo

Hello,

I have a question about Sound of Stereo their set at I love techno...

When they hit "Doop (Dolby Anol Hard 90s re-LOL Edit)" into "Zombi nation" the first song kinda slows down before zombi nation starts.

I've tried it on my pioneers with Doop (Dolby Anol Hard 90s re-LOL Edit) Looped at 2:36 en then slowed it hard down with the WIDE pitch. It's the same for 5sec but then the awefull hitchclap comes from Doop (Dolby Anol Hard 90s re-LOL Edit) so it kinda messes up the mix

anyone got a tactic for this one?

You can hear it at +/- 1:50:50
