So I just finally figured out to do this after seeing it in a video! I remember hearing about this feature but could never figure it out. Not sure if Im seeing this correct tho, but are you able to change the slope in the eq section while using the view with the knobs? Im only seeing the option while using the view with the value bars. I much prefer the view with the knobs
Right click on knob and select from context menu.
FYI: Although the slider view has a select button at the right, the context menu is also available in this view as well as in the Pre section of the mixer.
