Yes.

What are the chances that it could be a buffering problem? The firmware
update would be large, whereas control messages would be small. I'm
taking a wild guess here, and it wouldn't surprise me if I'm completely
wrong.

The device has a different number ports, depending on how it's
configured. I've just configured it for maxmimum ports, and connected
ardour to all ports, in both directions. Unit sends, but doesn't
respond.

I specifically asked them that several times. They said they did.

My next step is to get a standard midi cable and connect it that way,
see if that works.

Is there anything else I can do from a software point of view to see
what's happening?
