Hello!

I don't use qsynth/fluidsynth directly from Rosegarden. I use 
Rosegarden's fluidsynth-dssi instead. That avoids the whole connection 
problem since the connection goes through Rosegarden to JACK.

I get there through:

 1. *Studio* menu > *Manage Synth Plugins*.
 2. Click on the dropdown arrow where it says <none> and pick
    "Fluidsynth DSSI plugin". Do this for as many synth plugins as you
    might need. The way the DSSI works, it offers a separate synth
    instance for each instrument.
 3. Click *Close*.
 4. Right-click on the track you want to assign to the plugin.
    Pick*Synth Plugin* > *Synth Plugin #1* (or whichever item number you
    picked when you picked the plugin above).
 5. In the *Instrument Parameters* for that track, click on *Editor*.
 6. Click *Load Soundfont*, navigate to your soundfont, select it, click
    *OK* to install it.
 7. In the *Editor*, pick the instrument you want to use. Close the
    editor window.
 8. In the *Track Parameters* window, make sure the instrument you want
    to use is selected.

Then you should be ready to go.

Sorry, I only have the English version here so I can't provide the 
Italian labels.
