Motorized volume of Midi Keyboard Controller

Hi guys.
Are one new electronics I need your advice.
I make music with your DAW Logic Pro 9 and using it to play live with 3 controller midi Behringer UMX. So far so good, but I would like to replace the volume manual of my three controller with motorized faders. How can I do?
I am attaching a picture of the card where is the volume with manual faders.
Thanks for collaboration!!!
Roberto! :confused:

That picture is not very instructive. Try to find a data sheet of the module.

Also explain what the motor should do. Letting a motor turn some knob is a mechanical issue, not related to an Arduino. It may be simpler to replace the manual controls by an Arduino that outputs equivalent MIDI commands.
