Hiya,
A few years back I was using my BCF2000 with ardour. After upgrades
to my computer hardware and Linux distribution the combination no
longer works.
The BCF shows up in /proc/asound fine. I can send and receive data
with the BCF using amidi.
The test of tracing communication between the BCF and ardour fails.
I think this is because the mcu (port?) of ardour isn't connected to
the BCF. But, qjackctl won't let me connect those. They don't
show up in the MIDI tab of qjackctl. They only show up in the ALSA
tab of qjackctl. A long time ago there was an issue with my
distribution where qjackctl wasn't linked against libasound. But,
that's not the problem this time around.
I know people would need more info from me to help me troubleshoot
this. But, I'd rather not spew 5-6 pages of stuff to the list.
What would be useful here?
Thanks....

run a2jmidid -e
if you want a second rate solution, use JACK's "builtin" ALSA MIDI support
via the "MIDI Driver" selector at teh bottom left of the setup dialog.

Skipping the BCF2000 doesn't seem right.

Right now MIDI Driver is set to "raw". I'm not sure when or if
I set that, or whether it might be the default.

I've got it half working, thanks to the advice of those who
responded. Half working means that the sliders on the BCF move
when I move the sliders in ardour. The slider to slider track
assignments look right too.
Tracing the MIDI traffic of mcu I get "input" when I move the BCF
slider, and I get "output" when I move the ardour slider.
My setup is currently running MIDI Driver of qjackctl as "none"
in combination with running "a2jmidid -e". In the MIDI tab
of qjackctl's Connections window I have ardour's output ports
(control, mcu, and seq) all connected to the BCF MIDI 1 input
port. I also have the BCF MIDI 1 output port connected to all of
ardour's input ports.
Now all I need to do is to figure out how to get the BCF sliders
to move the ardour sliders. The way I've got it leaves me
hopeful. But, it's not yet useful.
Cheerio...

although it does sort-of-kind-of-work, i cannot recommend ardour 2.X's
support for the mackie control protocol.
the entire thing was reimplemented for 3.0 and works vastly better.

With 2.8x it works very well if in ardour the raw device is used instead
of the jack device.
From ~/.ardour2/ardour.rc:
<MIDI-port tag="mcu" device="/dev/midi-bcf2000"
mode="duplex"
type="alsa/raw"/>
...
<Option name="mackie-emulation" value="bcf"/>
And in /etc/udev/rules.d/60-symlink.rules I have:
KERNEL=="midiC[0-9]D0", ATTRS{product}=="BCF2000",
SYMLINK+="midi-bcf2000"
Unfortunately ardour removes/rewrites the entry in ardour.rc whenever
the device can not be found.

I might give that one more whirl. But, I won't spend a lot of time
on it.

Excellent! I never did figure that out. I've used "midiC3D0", as
that's where my BCF2000 ends up.
Unfortunately ardour removes/rewrites the entry in
ardour.rc whenever
the device can not be found.
I've noticed. But, if I turn on all the outboard gear, then start
jack, then start ardour, then it worked very nicely in the past.
Thanks much....
