[LAU] help with a2jmidi/a2jcontrol Dbus error.

Hi All I am having trouble getting a2jmidi to work. Any help would be most appreciated as I have upgraded my soundcard to an FFADO device, but really need my MIDI devices available to jack (i've been happily using ardour3 svn for a couple of months now) Specifically, I can't seem to use a2jcontrol to map ALSA midi devices into jack. (The same happens in reverse too). "a2jcontrol start" appears to work fine, "a2jcontrol status" reports bridge started but when I actually try to map I get the following error. allan@daw ~ $ a2j_control ma2jc 24 1 --- map ALSA to JACK capture port DBus exception: org.gna.home.a2jmidid.error.unknown_port: Unknown ALSA sequencer port 24:1 (capture) The port exists and is visible in the connection menu for qjackctl. Here is my output from aconnect -l (edited) client 24: 'USB Device 0x86a:0x01' [type=kernel] 0 'USB Device 0x86a:0x01 MIDI 1' 1 'USB Device 0x86a:0x01 MIDI 2' 2 'USB Device 0x86a:0x01 MIDI 3' 3 'USB Device 0x86a:0x01 MIDI 4' 4 'USB Device 0x86a:0x01 MIDI 5' 5 'USB Device 0x86a:0x01 MIDI 6' 6 'USB Device 0x86a:0x01 MIDI 7' 7 'USB Device 0x86a:0x01 MIDI 8' 8 'USB Device 0x86a:0x01 Broadcast'
