yes, that was the problem. Jack was set to 48000 while Qsynth was set at 
44100. When both are at 48000 the "Free Music Instrument Tuner" reports 
a nice 440Hz Concert A with the Virtual Keyboard. But this doesn't seem 
to affect the other synth that I tried: ZynAddSubFX: with this one, 
either 44100 or 48000 sample rate produce a concert A in tune...

In any case, I think the problem can be considered solved now. Thanks a lot,

Ángel de Vicente
