hi every one,

I have been trying to get a midi drum machine connected to Hydrogen.  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?

I am using Ubuntu Studio based on Ubuntu 16.04.6 LTS.  I haven't upgraded due to all the unfinished projects I have going.
