MIDI Controllers tend to be very flexible in how you assign knobs, sliders, pads, etc. In Pro EQ it's super easy to configure a mapping between a controller and an EQ parameter. For instance, here you can see that I right-clicked the Gain knob for the LF band in Pro EQ. I then assigned it to knob 13 on my Xboard controller. Now I can increase or decrease the gain of that band with a knob 13 on my Xboard controller. I could go through and assign all of the knobs on my Xboard to all of the parameters in Pro EQ if I wanted. When you choose a MIDI controller, choose one with lots of knobs or sliders that can be arbitrarily assigned to any parameter.
