This is the right thing to do, no more problem with
the usb and alsa, even if i let the midisport
connected to my pc, but I had to add in my
/etc/modules.conf:
options snd-usb-audio enable=1 index=1
alias snd-card-1 snd-usb-audio
And, it must be after the the audio card
configuration.
I've got a Midisport 2x2 USB, which run with
EZbusmidi.
I've got few configuration problems:
- With AlSA, i have to plug the interface after
RedHat
had been launch, otherwise ALSA intervert the
number
of my cards:
The USB host driver get initialized, and loads all
USB device drivers,
before ALSA is initialized.
Put the line:
snd-usb-audio
into the /etc/hotplug/blacklist file to prevent
this.
- With ardour,
I set up my ardour.rc file like
that:
Midi-port tag "Midisport"
device=/dev/snd/midiC1d0
...
It works, i've got MTC on port A, but i can't find
the
device for port B. I tried midiC1D1, MidiC2D0 :
it
doesn't work.
Both ports are available under this file, but this
is an internal file
that should be accessed by the ALSA library only.
You should configure your program to use ALSA MIDI
ports named
"hw:1,0,0" and "hw:1,0,1". If your program doesn't
support this, load
the snd-virmidi driver, connect its ports to the
2x2's ports (with
aconnect or kaconnect), and use the virtual ports in
Ardour. (If
loaded as card #2, the files for these will be
/dev/midi02 and
/dev/amidi02.)
