Sorry, I re-read the initial post -- 4 notes, hrmmm. That points
to a hardware issue but aseqdump doesn't show additional events.

Although I haven't delved into the code, the translation of NOTE ON (0)
to NOTE OFF should be happening at a much lower level than user-space
software. There is one standard for midi note on/off and it is clear
that note on (0) must be interpreted as note off.

Have you tried playing it back through a different sound generator,
possibly external gear attached to your 20:0 port?

Just as a test, what is registered when you route your keyboard into
kmidimon and route kmidimon into qsynth (all defaults, simple piano
patch)
- does kmidimon show 1 note-on/note-off only
- does qsynth output correctly?
