Hmmm, my JACK uses the default 2 for Periods/Buffer using Intel HDA and 
I don't recall getting any crackles ... but then I haven't figured out 
how to make JACK work with QSynth ... it seems I can have QSynth 
running, but then JACK won't start (says something else is already using 
the hardware), or I can have JACK running but then QSynth won't start 
because something else is using the hardware ... well, lets see. If I 
start JACK first, then tell QSynth to use JACK as its output, then it 
started and played once from Rosegarden. Next time I tried it, QSynth 
says "Could not connect to any physical jack ports: fluidsynth is 
unconnected."
