Yeah – very confusing at first. The Mackie Control thing can be messy, since it’s effectively a re-mapping of various midi events including notes across potentially all 16 midi channels.
When it was first invented, that never caused a problem, because the early midi control devices were only control surfaces (i.e. faders and buttons and knobs).
But with many modern devices, we now have a lot of combination devices that are both: playing an instrument with keys or pads AND a control surface.
So I’ve pretty much stopped using the Mackie Control protocol, and use the Generic Remote, when I want to use the knobs, buttons and faders on a modern keyboard controller or drum pad based controller for Cubase commands.
