[LAU] qjackctl, qmidinet, touchdaw, reaper

dear list members, I'm trying to have my computer automatically establish a connection between qmidinet and qjackctl resp. reaper so that I could just start the jack-server via qjackctl, then start reaper and have touchdaw working (via qmidinet). the connections can be established very easily, only I don't know how to establish that said flow. the issue is that qmidinet needs to be started/reseted after jack is up. I thought I just use the option in qjackctl to run a script after jack is set up but if I put 'qmidinet' here it doesn't work, because of some conflicting processes I don't understand so far. does anybody of you know what I could do? I thought of a command to reset qmidinet just like its gui offers, that would be the easiest and a sane way. is there such command? thank you very much! christoph
