How come the echo freeze transition goes wrong in traktor ?
When i do the echo freeze, it works perfectly, but when i do an echo freeze transition it goes wrong and the echo freeze sound becomes ugly ?
I’m not an expert but more a kind og beginner 
You do you mean by ugly ?
Could it be due to the difference in BPM between your two tracks ?
Because once that you have hit the play button in order to stop the deck on which the echo freeze trick is happening, the echo will use the BPM of the new incoming track as a reference.
when i do that the SYNC function is not ON.
(but yeah the bpm difference is huge (86 bpm to 128bpm)
ohhh ok the master bpm changes so the echo freeze bpm changes too.
ok thanks dude !
