[PlanetCCRMA] a2jmidi

[Raphael Raccuia]

Hi,
I used a2jmidi and it worked great, it's easy to compile... You can 
start it automatically in qjackctl settings (start - stop commands)... 
It's the only way I know to connect alsa midi to jack midi...
good luck

There is a MIDI THRU under the ALSA tab, but I still can't see a way to connect the hardware midi (JACK midi) to ALSA midi clients.  What am I missing?
