Interesting idea, though I'm not sure adding random delays
really "humanizes" things.  Of course I realize this is mostly
something you've put together as a learning exercise.  BTW,
in case you're interested in reading some ramblings of another
beginning ALSA MIDI programmer (me), you might check out this:
http://www.geocities.com/smcameron/linux-audio-notes.html, which
is kind of a log I've kept for the last year or so.

Maybe there are some interesting links in there, if nothing
else, or maybe some humor at my expense, LOL.

For a humanizing type feature of my drum machine application,
I added a per instrument (per note, really, as MIDI drums
instruments are mapped to notes) feature that allows a particular
instrument to "drag" or "rush" which is to say, fire off a little
late, or a little early.  My implementation is a little buggy, in
that when dragging or rushing causes an instrument to slip across
a measure boundary, things get a little squirrelly, but the idea
is there.  I got that idea from reading a little instructional book
about playing the drums, I guess it's common practice among drommers 
to keep some important instruments in fairly strict time, while kind
of messing about with some others.

I guess for a filter app, "rushing" is not really possible, without
a time machine, though "dragging" every other instrument would 
amount to the same thing, plus insertion of latency.
