Okay. Worked awhile today and got it going. Ending up playing a file to 
my external synth and then sending one track to qsynth. The operation of 
all this is not the intuitive ... but, I got it running. Gotta say it's 
neat ... but gotta say it sounds awful as well. To my ear the tracks 
going to qsynth are out of pitch and time with the external keyboard. 
But, I suspect that is to be expected?

Now, I suppose I could bank up a bunch of software synths and get it 
running.

Yes. I've just installed the eaw font and it sounds much better than the 
default. Anyone know where I can grab anything better than that? I did 
get something called FLuidR3 GM.sf2. It runs fine with fluidsynth, but I 
don't see anyway to use it with timidity. I can't find the program to 
create the config files.

Yes, that part I understand. Guess what I was meaning to ask was what 
quality I could expect compared to an external flash-card based recorder 
I'm using now. Same/worse/better?

Oh, if anyone is interested I have put a few recordings I'm made with 
MMA, etc. on http://www.mellowood.ca/music/recordings

Best,
