[ardour-users] problem with connection to midi controller

[Ichthyostega]

Hi all,

maybe someone can give me a hint what I am doing wrong?
I still have problems connecting a Behringer BCF2000 to ardour

See: http://ardour.org/manual/using_a_bcf2000

 * running ardour on "64Studio" (a debian distribution geared at multimedia on AMD64 machines)
 * now using ardour 0.99 compiled from source
 * updated the firmware of the BCF2000 to V1.10


Basically, if I just fire up ardour, I can't set up the necessary midi connections.
qjackctl doesen't establish the connecttion after I click on "connect". When trying
aconnect, I get a message "Resource temporarily unavailable" (see details below)


/But/, if I manage to have the midi ports of the BCF2000 beeing used by another application
/when I start up ardour/, I can establish the necessary connections. After this the
BCF2000 works as expected (can control ardour via BCF2000 and get any parameter feedback)!

any hints, pointers or help greatly appreciated!

# observations
#  1) this second time, ardour is client 131
#  2) aconnect -i reports a connection from 129:0 to 72:0
#     but there is no client 129 (only one ardour process running at that time)
