[linux-audio-user] QSynth dumb question

So, I read the man page, I poked around on qsynth.sourceforge.net,
I read Dave's article at http://www.linuxjournal.com/article/8354
and I must be missing something really obvious, because I'm stumped:

How the heck do you use the channels dialog?

(qsynth 0.2.5 by the way.)

For example. I have added several soundfonts via the Soundfonts
dialog. I click the Channels button. Per Dave's tutorial, I expect to
see only names from the last font in my Soundfonts list. But I see a
mishmash of names from various soundfonts. And I can't seem to DO
anything with them. Per Dave's tutorial, I try right-clicking. I get
a popup menu with Edit and Refresh options. Fine, I choose Edit for
channel 1. I get a dialog labelled Channel 1. There doesn't seem to
be any way to actually edit anything here. For example, right now I can
select bank 0 or bank 2. Bank 0 includes this:

prog Name SFID Soundfont
---- ---- ---- ---------
1 BritePiano 5 TrachtmanSteinC_XFade2_2001Aug16
0 GrandPiano-Multi 5 TrachtmanSteinC_XFade2_2001Aug16

And bank 2 includes this:

prog Name SFID Soundfont
---- ---- ---- ---------
0 Roland 64VoicePiano 1 Roland_64VoicePiano

I can't find any way to add other programs, or remove the ones that
are showing. I seem to be permanently stuck with these. I don't even
really know how I got them in there :-(

As far as I can tell, what I'm actually hearing is bank 2 program 0.
I have resorted to every combination of mouse buttons and keyboard
modifiers I can think to try. Nothing I do has any visible or audible
effect.

Help!
