fons, recall the difference between latency and jitter. the problem
with the -Xseq backend (and -Xraw too) is that it causes really bad
jitter in addition to whatever latency is present. a2jmidid (at least
the current git version) doesn't do this - it keeps the jitter as low
as possible and the latency is constant.
