[ardour-dev] selecting midi devices

Thanks, I tried your idea of multiple Seq devices but I could only see one
in JACK. I kinda understand why but I don’t know how to change it. In JACK,
under the ardour drop down box I see 0:Seq but none of the other devices, I
think this is because I haven’t assigned a number to the devices. The other
devices are named Midi 1, 2, 3 and 4. 

Any ideas??

Rosegarden does automatic alsa-sequencer connection stuff, and hides it too.
It is quite clever, although too clever for my taste.
Ardour doesn't do this.
What I do: 
remove the references to hardware midi inputs from the .ardour/ardour.rc.
Set all the midi input ports to seq in the options window
connect it all in qjackctl in the midi tab of the connections window.

The alternative is to specify the ports are hardware ports in 
the .ardour/ardour.rc and thereby preventing other midi software from 
accessing that port.

<MIDI-port tag="hw:1" device="/dev/snd/midiC1D0" type="alsa/raw" 
will specify the first device on the second card for midi.
Look at /dev/snd to see what you have available.
And I guess that the 3rd and 4th port need to be specified output only but I

don't know what the keyword is. Probably mode="playback" or mode="output".
