Reply to Traktor S2 Scratching

Hello DJTT

Just quick question, i made some research but did not find anything.
Recently I bought Traktor S2 and one of the things i'll try at first was scratching, i'm not into scratching or things like this but just try
Sound of scratch was very, very, veeeery how to say, digitalized, i guess, very robot like
like it has some transpose effect on it or smth (all effect are off). I try it with diff genre tracks, like dnb, dubstep, hip-hop, result is same, very digital sound.
I changed latency setting, sample rate - no result.

I'll upload video lately

Thanks
