I think what probably happened is this.

1. You had the generic General MIDI Device

2. You set up QSynth and created a new device in addition to the above, 
and called this qs1.

3. You never loaded any programs into that device, so you can't change 
banks and programs, because there are no programs to change.

Since that soundfont is General MIDI anyway, the quickest and easiest 
thing to do would be to go to Studio - Manage MIDI Devices and change 
General MIDI Synth so it's playing via QSynth.  (Synth input port 
130:0 or whatever it calls itself these days.)

If you go that route, you'll be using the existing device and its 
existing banks/programs, which happen to match what you're trying to do 
anyway.

Alternatively, you could load the programs out of the .sf2 file so that 
qs1 also has banks/programs available.

I'm writing this in a huge hurry, and have glossed over a lot of 
details.  If this doesn't give you the boost you need, I can get into 
more detail once I have more time.

What do you mean by different? You always need at least one soundfont.

 By midi channel you mean communications like 131:0?
No. These are MIDI ports that can point to a softsynth or a hardware 
synth or other MIDI equipment.

 [I thought a midi channel was like one of 16 musical
 instrument sounds available per synthesizer]
Yes. But each MIDI port can have it's own channels

 I managed to create 3 instances of Qsynth and then included
 them in Rosegarden Manage-Midi-Devices and got them to
 play some segments. I get nice sound quality with this
 method, way better than Zyn, but..  How do I set up one of
 the 128*banks available 'programs' or musical instrument sounds?

Banks are not programs. There are 128 programs in the General Midi 
standard. Each program sometime has variations that can be selected with a 
bank select.

You can select both banks and programs you want on the main screen in 
Rosegarden in the Instrumentparameters section in the Special 
parameters on the left side of the screen. (You might have this not 
openened?)

Yes, but loading one into each instance is necessary.

 [I thought a midi channel was like one of 16 musical

MIDI-Channels go from 1 to 16. In the Hardware-world MIDI is a bus
system where you can daisy-chain many synthesizers. Each synthesizer is
set to a unique channel so note-on- (and other commands) can be directed
to the desired synthesizer. The commands include a field for the
channel-no.

 them in Rosegarden Manage-Midi-Devices and got them to
 play some segments. I get nice sound quality with this 
 method, way better than Zyn, but..  How do I set up one of 
 the 128*banks available 'programs' or musical instrument sounds?  

Zyn and fluidsynth (the core of qsynth) are totally different. Zyn is a
synthesizer that has configurations or patches for each sound. There
is no standard way of organising them.

Fluidsynth is a soundfont-player or a play-only-sampler. In the
soundfonts there are samples and settings. In the case of a General
MIDI soundfont there is a standard way to organize the sounds.

I am no expert in the world of assigning descriptions to sounds. There
is much more to know. For example there are some description files for
some well known synthesizers and their factory sounds. 

 Right clicking on the track title in Rosegarden offers up 
 to chose the Qsynth instance and 16 numbers, how do I 
 corelate those numbers to sounds in the loaded sf2 file? 
 Suppose I want that track to play a deep cello, where and 
 how do I set that?  
 
 So much for virtual midi 'devices'.

I organize it differently. For each instrument I use a separate track
and a separate synthesizer plugin instrument. Then there's no hassle
with MIDI-channels:

Track 1 - fluidsynth synth plugin - instrument 1 - soundfont x with program a
Track 2 - fluidsynth synth plugin - instrument 2 - soundfont x with program b
Track 3 - zynadsubfx synth plugin - instrument 3 - program c
Track 4 - whysythn synth plugin -   instrument 4 - program d

It's handy to always have track number and instrument number equal. This
is not always possible since you can have MIDI, synth plugin and audio
tracks.

It's a good idea to have a fluidsynth with a selected drum program (e.g.
standard) on track 10, instrument 10. It can be used as metronome.

My way of doing it is having as many synth plugin tracks as I need, e.g.
from 1 to 12 and then start the audio tracks behind.

  Bit I recommend using fluidsynth as synth plugin instruments in
  Rosegarden, each with its own soundfont. Latency is much better and
  Rosegarden remembers all settings. It's no problem having 3 instruments
  with FluidR3_GM.sf2, each with a different sound selected and 2
  instruments with PC51f.sf2.
 
 This bit I don't understand but if it cuts down on latency 
 then I want to understand it because I'm using OpenSUSE and 
 they no longer bother with low-latency kernels. However the
 Rosegarden manual say this about plugins (I presume 'as
 opposed to midi devices'): 
 
 The use of plugins has a cost in CPU time, as audio processing 
  in real time usually takes a significant amount of work even on 
  a modern CPU. It also has a potential cost in reliability: when 
  Rosegarden is running a plugin, if the plugin hangs or crashes, 
  so does Rosegarden. Many plugins are very reliable, but it's 
  inevitable that some will not be so well tested. 

CPU time is always needed für synths, regardless if they are loaded as
DSSI-plugins or if they are started as standalone programs like Qsynth.

The author means LADSPA-plugins to create effects like equalizer,
reverb, phaser and others. But they are meant to be used, so use them if
you need them :)

 Anyway, I right click on a track #3 title and select Synth 
 Plugin and the number 14 meaning that this synth DSSI plugin 
 (to be next defined) will be used by Rosegarden internally 
 without setting it up as a Midi-Playback-Device. This shows 

Yep. But I recommend to use synth plugin instrument #3 on track #3.

 up under Track Params as info but there is nothing to do there. 
 Next I go to Instrument-Params which shows the same Synth 
 Plugin #14 and I click the no synth button to define this 
 #14 plugin. A dialog pops up where I can select Plugin: 
 Fluidsynth DSSI plugin
 
 And then what? I can change the volume here and there are also 
 some effects plugins too but where do I set the musical 
 instrument sound I want this 'Fluidsynth DSSI plugin' that 
 is plugin #14 to play track #3 using xyz.sf2?

- Right-click on track #4's

That's the selection I was looking for but couldn't find. I can 
also do that kind of setup for the creation only of a new segment 
that doesn't exist yet. I found it where you say only when I selected 
General Midi for the track. But General Midi isn't what I want to 
use, it's Synth plugin, more specifically Fluidsynth-DSSI or an
independent instance of qsynth.  

If I select General Midi for a track then I do see the bank/prog 
dialog where you say and I can select one of the 128 (maybe more) 
musical instrument sounds such as #20 Church Organ. I did this, 
but playback produces no sound at all.

Then if I select Synth plugin  Fluidsynth-DSSI there is still 
no sound and what's worse the Instrument Params bank/prog dialog 
isn't there anymore.

If I next select qs1 (my instance of a running qsynth set up to 
use the FluidR3_GM.sf2 font file) then I do get sound but it has 
nothing to do with the musical instrument I want and the bank/prog 
dialog is still gone.

That sounds good and less confusing and I have already tried it, I

 - Right-click on track #4's (edited to #3) title, select synthesizer plugin #3

OK

 - On the left box (Instrument's parameters) click the No synthesizer
   button and select fluidsynth dssi plugin

OK


 - click the button below (audio ...), a little window appears

No such button, so I can't continue :-(

 - click load soundfont and load your soundfont
 - then select your instrument in the list. Test it by clicking send
   test note. I always have to select the desired instrument, select
   another and then select it again until it works.

Thanks for the response.

I need to follow through on this using the ZynAddSubFX approach

- I entered rosegarden's midi setup dialog and created a My-Zyn-In 
  entry paired to the 131:1 ZynAddSubFX (write) available output 
  on the right. 

- With Zyn launched I set all 16 channels up for one instrument or 
  another. I can hear them all and they all have names  numbers
  like 39 - Church Organ 3. Thus one can set  store each of 16 
  channels to any one of hundreds of ZynSubFX instruments

- Finally I can save the Zyn settings to a file so I don't have 
  to go through all this each time
 
- If Zyn is set up and connected through Qjackctl then clicking on 
  a track in rosegarden I get My-Zyn-In as an option with the 16 
  associated channels to produce the subject sounds.


Now how do I do the same thing with Qsynth?
