The events are sent to Timidity (128:0), not to your program.

And you wouldn't want other programs to be able to intercept events
not directed to them, because those events could contain sensitive
data.  Uh, yeah.  ;-)

Anyway: load snd-seq-dummy, connect a through port to both Timidity
and your program, then play to the through port.
