in case you've missed (on the qjackctl homepage) there's this article by
Dave Phillips on Linux Journal,

- At the Sounding Edge: Using QSynth and QJackCtl

although it deals with qsynth instead of qsampler, it might give you some
ideas. alas, you may find qjackctl use all over Dave's outstanding
blogging :)

about your particular midi controller, how do you connect it to your
computer? usb? midi over the game port? anyway, if things are working
properly, the ports should show up at the midi (alsa) connections window
on qjackctl.

re. qsampler, it is the basic front-end to linuxsampler, and should start
it as default.

once up and running, first thing to do is add/create a sampler channel.

there you select one instrument file (.gig) and which input and output
devices should serve midi and audio respectively. Choose "ALSA" for MIDI
device type and "JACK" for audio type, provided you've got jackd started
with qjackctl.

from that moment you can make the proper connections,
   midi controller -> linuxsampler
   linuxsampler -> alsa_pcm or system
