Uh, port already exists? The Firewire ports are not visible from Alsa
(I have blacklisted snd_dice since it does not play well with the
Alesis io|14) and there just is (seq and raw, respectively):
dak@lola:/usr/local/tmp/lilypond$ aplaymidi -l
Port Client name Port name
14:0 Midi Through Midi Through Port-0
20:0 UM-4 UM-4 MIDI 1
20:1 UM-4 UM-4 MIDI 2
20:2 UM-4 UM-4 MIDI 3
20:3 UM-4 UM-4 MIDI 4
dak@lola:/usr/local/tmp/lilypond$ amidi -l
Dir Device Name
IO hw:1,0,0 UM-4 MIDI 1
IO hw:1,0,1 UM-4 MIDI 2
IO hw:1,0,2 UM-4 MIDI 3
IO hw:1,0,3 UM-4 MIDI 4
but those have nothing to do with the jackd error (right?). So jackd
somehow gets in a loop or something?
Ok, so it's rather
jackd -X alsarawmidi -d firewire -r 96000 -p 512
but you wouldn't know from looking at the manual page. So what's with
the useless error message and the useless manual page?
