I have a bcf2000 and use it with ardour and many other programs with
none of the problems you describe.  In my experience, problems like
these are caused by a program which is using a raw midi device. 'lsof
/dev/midiWhatever' might be able to tell you what is using it. You might
also try making the same connections to a program that is not ardour.

Also, there was a firmware update I did to my bcf2000. Instructions are
in the ardour manual at ardour.org. I don't think that would solve your
problem, though.
