A problem with the regulators in the traktor pro 4 software

DJ_Vladyzes

When I turn the volume control Gain or the EQ controls in the mixer using the computer mouse,left or right their,then they increase or decrease the signal by a few percent at once when I turn them, not step by step, not 1 decibel more or less at a time, which is not convenient, somehow it can be improved, these extra parameters do not work on the regulators,which are marked in the screenshot.For example, I need to set the gain to -30.0 decibels, I turn the knob up and down, but I can't exactly set it to -30.0, I get -25.4 decibel control knob jumps, so I don't have enough sound already, and so on.I give a little more - another - 30.0 I give, it is already too loud, above the master, the sound distortion has already gone, the sound is not of high quality then.
