Reply to Echo Freeze effect on DJM

Hi guys,

When I Dj with Traktor, I use the Echo Freeze effect a lot to let a song echo out. I was wondering, how would you do this on a DJM 800 or 900? Just apply the echo effect and pull the fader down? I don't own a DjM, but when I have to play in clubs, I would also like to use this effect.

I tried it once in a club on a DJM by applying echo and pulling the fader down, but I noticed the echo died out almost instantly.
