I assume he's got a patch loaded in QSynth and volumes are well ajusted.

In that case it sounds like he's either missing out in step 3 or 4, as  
in "MIDI info from the keyboard is not sent to QSynth" or "Output from  
QSynth is not sent to the soundcard". The easiest way to check is to  
use QJackCtl and check the Connect button.
It could also be that he's using the wrong Jack MIDI driver, check  
QJackCtl's Setup button and test different MIDI Drivers.
