No, it moves smoothly. Get to the _one_ end of its range too soon, and to 
_another one_ too long. I've tryed to set "volume" slider to the filter 
control, and the same result. It seems like Center is shifted. So the control 
becomes not linear.

Knob:
VR8 - CC23 (17 hex) (ch1) 
VR8(CENTER) - Note F-0 (11 hex) (ch 1)

Volume: (to compare)
VR2 - CC 12 (0C hex) (ch 1)

Different? I hope they are not. =)
All of Windows DJ-software recognize Filters knobs properly.
