**MF Echo Freeze Help** Need some Help DJTT Forum. I recently watched this video posted on DJTT a while back. It is about switching tempos using echo freeze then applying a filter to the echo. ![](https://us1.discourse-cdn.com/flex001/uploads/techtools/optimized/3X/b/0/b021827071c4d263f8b212a11482954b0464b5c6_2_690x431.jpeg)https://www.youtube.com/embed/7w18hImPt8U?feature=oembed&wmode=opaque&list=HL1325858452 Using Traktor Pro 2 and my midi fighter Instant Gratification, I press Echo Freeze, stop the track as Ean advised so just the Echo continues, but then when I apply a filter or any effect using the midi fighter or my other midi controllers, nothing happens? How do I get Traktor allow me to apply filters to the Echo? What am I missing from the video? Thank you. ---

it can’t be done the echo cannot be altered after the fact, as it’s a small loop with the effect the filter should work if your using the knob on the mixing panel ---

> [@HerbStrike](#): > > it can’t be done the echo cannot be altered after the fact, as it’s a small loop with the effect the filter should work if your using the knob on the mixing panel Not quite sure I follow. First you say it can’t be done? But He does it in the video? Then you say it should work if your using the knob on the mixing panel? > [@](#): > > there was some traktor version where the fx where post EQ/filter.. was fixed some time ago.. so make sure you have the latest traktor version I just got the Traktor Pro 2 upgrade in December so that shouldn’t be the problem. Thanks for the suggestion. Is there a way I can check this in the Controller editor to make sure the fx are setup properly just to be sure. ---

Is there a way I can check this in the Controller editor to make sure the fx are setup properly just to be sure. that’s odd. what version of traktor are you on? 2.1.2 is the last one. it has nothing to do with the controller, it is traktors internal audio routing, which was screwed up for some time..
