Strange behavior with EFX: Delay

I cannot say that I got this issue before, since yesterday I have this strange thing.

Deck 1 is playing, I enable the effect 'Delay' and stop the deck when the effect is still enabled. Right after I start deck 2 and then the strange occurs.

Deck 1 gets this 'wobble scratch' sound, like a record is stopped and started within a half second. It is not controller related and not mapping related, because the video I recorded is made with no controller and mapping installed and the GUI is controlled by mouse.

The video shows the error twice, please check out what I am doing and listen carefully.

Traktor 2.10.013 on Win7.

 

Not making this video private would help.

 

I changed it, thanks for the info

 

That's normal with auto master tempo, you have a 130bpm track and a 78bpm track, the feedback is automatically adjusted from 130bpm to 78bpm when the master tempo change.

 

Thats it!
Disabling auto solves this problem. Thanks!

 

I was answering on youtube but hey cool you got your answer.

 

But if you disable the auto master tempo it wont change unless you "TAP" your tempo, so if you press sync the track will take that tempo. The auto behaviour takes the active deck tempo, thats is whats happening in the video the moment you stop the deck the master tempo changes.
