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.)
