Dir Device Name
IO hw:1,0 M Audio Delta 1010 MIDI
IO hw:3,0,0 BCF2000 MIDI 1
IO hw:3,0,1 BCF2000 MIDI 2

This is with my Delta 1010 turned on, but nothing connected to
its MIDI ports. I also have my BCF2000 on, and MIDI cables
running between it and my Mackie MCU. BCF MIDI out/thru to MCU
in, and BCF in to MCU out. In this configuration the MCU can
control Ardour. But, Ardour can not control the MCU.

This is running behind ardour

10319 ? SLsl 0:04 /bin/jackd -dalsa -r48000 -p1024 -n2 -D -Chw:1 -Phw:1
10333 pts/5 SLl 0:02 a2jmidid -e

At this point I'm thinking

- MIDI ports on the Delta 1010 don't work as I would expect.
  Brent also said this about his 1010.
- The BCF2000 functions as a unidirectional MIDI host, like
  a partial USB<>MIDI translator.
- A real USB<>MIDI translator, e.g. Midisport NxN should help.

I'll report back after my next steps.

Thanks....
