Hello,
The mackie MCU (Mackie Control Universal) seems to be a very sophisticated unit akin to a mixer for audio and midi (??). I've looked at a very detailed review of the device at
https://www.soundonsound.com/reviews/mackie-control-universal and to be honest I'm not much the wiser. You really need to be asking directly of Mackie at mackie.uk@rcf-uk.com or via
http://www.mackie.com.
I would comment however that it seems that a lot of the functionality of this unit related to it's use with/via your DAW, and the extent to which the DAW supports/communicates with the MCU. The review noted above suggests that this is better with some DAW systems than others. Maybe the answer to your question will depend more on the specific DAw you use, than anything else.
Have you tried connecting the MCU to your DAW using the midi/usb connector (hopefully NOT using one of the cheap Chinese ones which have various problems, as detailed here and other places), and did they communicate?
