note that I had the same issue compiling qjackctl from github
you have to install libasound2-dev
./configure
should report this line:
ALSA MIDI Sequencer support . . . . . . . . . . .: yes Phil

The first time was not a problem through Qjackctl. second time they would not connect. I tried some tutorials on youtube but now I have lost the alsa tab in the Connect screen. I thing a2jmidid -e was the command that stuffed it. I have tried uninstalling and purgering Jack but after reinstalling it is the same. Can some one help or at least point me in the right direction?There is ALSA MIDI and JACK MIDI. Two worlds. You can bridge them with a2jmididi and then connect the ports as appropriate. a2j_control start a2j_control stop _______________________________________________ JackAudio mailing list JackAudio@lists.linuxaudio.org https://lists.linuxaudio.org/listinfo/jackaudio
