Not sure if this helps at all, but I'm just reporting that midi input 
over jack works for me on an old Ubuntu 10.10, Denemo 1.0.9, locally 
built with jack enabled... no problem.  In general my jack connections 
have been without a problem on this system, and appear to be robust in 
the sense of multiple simultaneous connections which never interfere 
amongst themselves, but rather the whole thing works like one good 
mixing board, reliably.  Also, when I switched from Fedora to Ubuntu for 
my main system, I found that things became much easier, on many levels, 
including availability of packages and doing local builds, and 
documentation and online support.  And I finally stopped tinkering with 
the jack-audio and started to actually use it and reap its benefits.

I tried to fully understand the essence of this thread, but I may have 
lost sight of the issue; apologies in advance.

Also, FWIW:  my "aconnect -i -o" isn't even listing "denemo" as one of 
the midi clients.  I don't have Philip Rhodes'

    client 130: 'denemo' [type=user]
        0 'midi_in         '
        1 'midi_out        '


even so, my jack/midi -> denemo input works.

(i have a question regarding the midi input feature, but that will be a 
different thread)
