  In Qtractor I can play the tracks through
Timidity.  The Track
 dialogue offers me sounds from the FLuidR3_GM soundfont and
 also soundbank-emg.  But these sound identical, and I think
 only FluidR3_GM is being used, which I have set as the default
 in Timidity.

 I would like to use other sound fonts (e.g. Virtual-Playing-
 Orchestra3), but I have never worked out how to achieve this.  
 Virtual-Playing-Orchestra3 is in the sfz format, to use it you'll
 something like this:

 For using other sf2 files you may checkout this one:

 Thank you for those suggestions.  I have now managed to get Fluida
 installed (in addition to WhySynth).  I also now have the relevant
 directories showing up in Qtractor's View_Options_Plugins window,
 and
 both items show up in the MIDI/Instrument section of Track
 Properties.

 However, even if I select an instrument from one of these, I still
 do
 not hear the appropriate sounds.  I assume that I should be able to
 connect WhySynth or Fluida to Qtractor in the Connections window;
 but
 as I mentioned in my previous email, they don't show up there.

 Using the MIDI tab of Qtractor's Connections window I have "Midi
 Through" and "Qtractor" in the Readable column, and "Midi
Through",
 "Timidity" and "Qtractor" in the Writable column.  If I connect
 Qtractor to Timidity, I hear the FluidR3_GM sound regardless of
 which
 Instrument I have selected in Track Properties.  If I disconnect
 Qtractor and Timidity, then I hear nothing at all.

 I am sure there must be something very basic I am missing here, but
 I
 have no idea what to do next.  How do I get the Instrument I
 specify
 for a track in the Track Properties window actually to sound when I
 play the track in Qtractor?

 You need to activate the plugin (the little round toggle beside the
 plugin name) and enable 'montor' in the mixer strip for the track you
 want to hear. 
Thank you for that (and also to Rui for his reply).  I hadn't realised
that the little dot was a toggle and not merely a sort of "bullet-
point".

But even having activated the plugin as sugessted, I still had no
sound.  Eventually it occurred to me that, since (as I already
mentioned) I wasn't seeing anything in the Connections window that I
could connect Qtractor's output to, the problem was perhaps with Jack,
rather than Qtractor.  Most of the many settings in QJackCtl mean
little or nothing to me, but I did spot that "Output Device" was set to
"hw:NVidia".  Even I could recognize that that was inappropriate, so I
changed it to "default" and everything now works as expected.

Thank you again for your help in this.

David
