So, I checked what's going on:

24:0 Control change 0 64 0
The above sequence dumped by aseqdump shows only one note event
(lines 2+3: press+release) but I heard a delayed note as mentioned in
my first mail.
Actually, there are two note events and both are NOTE ON, one with
velocity of 82 and the other 0. The velocity 0 should be interpreted as
NOTE OFF.
I had a similar problem and solved it by putting kmidimon between my
keyboard and sequencer.
Could it be that qsynth doesn't handle NOTE ON with
velocity of 0 as NOTE OFF? Although I imagine that translation should
be happening at a lower level... just a guess.
