[Jack-Devel] a2jmidi and jack

I have a question about a2jmidi since I was trying to see if I can live without it to simplify setup. I am using Jack 1.9.10 JACK has 2 MIDI drivers: raw and seq. I would like to connect both 1) hardware MIDI ports (i.e. a USB midi cable 2) software MIDI ports (i.e. fluidsynth) I seem to be able to do it without a2jmidi for the former but have not managed with the latter. And, when I have a choice, what is the best option: opinions out there aren't uniform on this. By best I mean the most time accurate. Regards
