I just tried your first suggestion (reboot etc.) and then ran you commands again. Slightly different output, but the same result: the keyboard appears in the ALSA tab but can't be connected to anything else. david@eros:~$ killall -9 jackd a2jmidid qjackctljackd: no process found a2jmidid: no process found qjackctl: no process found david@eros:~$ jackd --sync -Xalsarawmidi -dalsa -r48000 -p256 & a2jmidid -e & qjackctl [1] 2416 [2] 2417 jackdmp 1.9.11 Copyright 2001-2005 Paul Davis and others.
