Well, seeing as various people (including me) invented the mappings,
Behringer wouldn't know about them ;-)

Nope, I'm using alsa/raw. I've updated the docs to make it clear that
alsa/sequencer are not working with the mackie code in 2.0-ongoing. It
will take a while for the website to be updated.

Ah, OK. If I set the bcf to u3, and use qjackctl to connect ardour:seq
to 1:BCF2000 MIDI 2, and tell Ardour to send MTC to seq, and I start the
transport rolling, then the MIDI A light on the BCF starts flashing

And if I put my nose really close to the MIDI A port on the back of the
bcf, I can almost, but not quite, smell the midi messages drifting
out :-p
