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.
