Long story short it is possible to have full control of your CTRL49 faders and fader buttons, just download the Dulplex tool go to settings in the Dulplex: Device/Configuration turn on Mackie/HUI for the in and out or to your preference and that should cover it, also in the CTRL49 I noticed you can have your MIDI set as “none” which is if I’m not mistakingis like Mackie/HUI or in Mackie’ that should give you full control of your controller. hope this help.
