Wolke,

Understanding the dev side and not the user side, that is the world
up-side-down for me ;)
http://trac.jackaudio.org/wiki/WalkThrough/User/jack_session

You need Jackd > = 0.120 or 1.9.7 and qjackctl 0.3.7

Start qjackctl, start JACK
Start an app with JS support (yoshimi)
Make the desired connections
In qjackctl 0.3.7, you have a session window, open it.
Save session
Make a *new* folder (be careful not to overwrite an other folder (should
become more safe in the next Qjackctl version))
Select that new folder to save the session to.
You can quit the session by just quitting the applications, or choose
save (save and quit)
You can load the session via the load button in the Session window of
Qjackctl, choose the right session folder.

HTH
