Reply to Rotary encoders on DIY midi controller and Traktor PRO

I am having difficulties with understanding how does Traktor interpret MIDI data coming from rotary encoders. I am building my own MIDI controller and my encoder works fine (atleast I believe):

No pitchbend: 0x00 0x40
Max pitchbend: 0x7F 0x7F
Min pitchbend 0x00 0x00

So, I mapped that encoder to "seek position" function in Traktor PRO but it acts all jerky: I spin the disk fast and position marker goes all crazy, left to right. No, it's not encoders fault - I analyzed data coming from encoders and there are no skips. The only reason I can believe off is that I need to code different counting mechanism for that encoder.
