Mackie MCU pro newbie

I just acquired a used Mackie MCU pro surface, and I’m a bit puzzled. The controls appear to be working exactly as I would expect, but when I select a track (or bus), and hit the EQ button, the surface says “no EQ in the track/bus”. After I add an EQ plugin (the one that comes w/ Ardour5) to one of the tracks, it still says the same thing.

Also, I would expect the plugin button to do something, but I’m not sure what or if it’s doing it correctly.

I’ve read the manual, but on operation of the surface, it’s pretty sparse.

I’m using the following versions:

Ardour 5.12.0 (64-bit) on Ubuntu 18.04
Mackie MCU Pro v3.0.0

At this time, the only eq it recognizes is the Mixbus eq. You will also notice that it does not do plugins yet either, which would also allow eq adjustment. I don’t know when such function will be added.
