Are you referring to changing the scale of the EQ in Edit Channel Settings, JLiRD808?
I.e. zooming the Equalizers area in towards an EQ range so that the top/bottom of the display show say, +6/-6, instead of the default +24/-24? This way, the max/min are scaled based on the zoom level and finer adjustments are easier to accomplish. Also, the EQ engine doesn’t have to be altered in any way, since it is simply the area that restrict the mouse movement within the visible (zoomed or not) range.
