Enigma by M-Audio is a software that allows users to edit all controllable parameters of Evolution products (MK425C, MK449C, MK461C, UC-33e and UC-17 X-Session). Enigma is easy-to-use : your Evolution keyboard or controller is actually shown on the screen. To assign a knob, slider or button on your Evolution product, simply drag the parameter from the list and drop it onto the controller you wish to assign.
