This shows you have JACK MIDI connections between rosegarden and
linuxsampler. both apps are alsa seq and midi goes:

rosegarden -> a2jmidid -> jack midi -> a2jmidid -> linuxsampler

qjackctl shows jack midi connections in midi tab, alsa seq connections
in alsa tab.

Those are JACK MIDI connections.

yes ;)

RG is not static bridge. I was refering to alsaseq-jackmidi static
bridges. a2jmidid is dynamic bridge, dynamic means, it automatically
creates JACK MIDI ports for ALSA seq midi ports. I've tried to exmpain
things in a2jmidid README:


My confusion about RG is, that I was under impression that rosegarden
does not create output alsa seq midi ports but just sends midi events to
exisiting alsa seq midi input ports. I think i've checked this but maybe
I just got it wrong. I dont really use RG.
