Pitch adjustments are sluggish/gradual instead of instant

[Landsnark]

Any clue on this one?

On my left deck (deck A) on my S4, when I adjust the pitch, it doesn't immediately change. It gradually moves to the pitch that I set. It acts almost the way that timecode does, when you adjust the pitch and Traktor's BPM indicator "catches up" to what it should be. (For the record, I AM using Traktor Scratch since I sometimes use a timecode system as well. However, it's not in timecode mode.)

This doesn't happen on the right deck... it adjusts instantly, just as you'd expect.

Any ideas??

Sounds like a dirty fader maybe.
