Can I suggest another improvement to the manual page, when you have
time, John?

Currently, the manual notes that mcu/bcf support only works with raw
alsa midi devices, and explains nicely how to configure ardour to use
said devices. Many users I would guess will have problems with the names
of the raw devices depending on the order in which they are switched on
(or worse, on races in the kernel usb stack).

There is a way to get udev to assign an attached BCF2000 a consistent
name under /dev/ however, by adding the following line to the udev rules
file / directory (on my system this is /etc/udev/rules.d/55-midi):

KERNEL=="midiC[0-9]D0", ATTRS{product}=="BCF2000", SYMLINK+="midi-bcf2000"

This will cause udev to create a /dev/midi-bcf2000 for any BCF attached
to the system, regardless of which alsa card number it gets assigned.
It might be worth mentioning this in the manual, until such time as mcu
support no longer requires the user to specify a raw midi device.

You might also suggest


as further reading.
