That makes my unit /dev/snd/midiC3D0 at this time.

I changed my /etc/ardour2/ardour_system.rc and ~/.ardour2/ardour.rc
files to specify:

When I start ardour2 now I get this on STDOUT:

The BCF2000 doesn't work. But, I don't expect that it would given
the above INFO regarding that unit.

Before looking at the website instructions I did not have that option
defined, and this was my "mcu" tag line:

With that setting for the "mcu" tag line I get this on STDOUT when
starting ardour2:

In that case nothing seems to fail in the INFO for the control
surface. But, the control surface still doesn't work.

I tried a few different combinations of settings in ardour2 through
Options -> Control Surfaces, including Generic MIDI, Mackie, and
Feedback. No setting there changes things for me.

I did manage to get ardour to lock up by unchecking the Mackie
option then rechecking it. Control-C was required to abort
ardour. Trying to restart ardour resulting in hanging; I forget
if that was before or after selecting my project. I fixed the
hanging on start-up issue by removing my ~/.ardour2/instant.xml
file.

I went back to my email stash and found 50 some emails on my
BCF2000 from 2007. All of what's in this email, and more, is in
that email. I've got quite a bit of homework to do. I'll report
back. But, if you think of something, please do let me know.

Thanks!
