I think Pedro answered you very well about the concurrency issue (which
is actually solved by removing one thread), and the midi resolution (64
samples).

As for the real problem, try to play a tune with "-o
audio.period-size=8192". I assume you can hear how terrible that sounds,
but if you don't there must be a difference between your machine and
mine (I can fix an audio sample if necessary).
