If you want to use alsa_seq's queues to

There's a file base/test/seq/generator.c in the Rosegarden source tree
that does basically what was described using the sequencer queue. It
does however schedule in real-time rather than beats (and so does
Rosegarden itself).

Pretty intersting, I just ran this and noticed it (the diff between
queue and gettimeofday time) drifts about 70 usecs per second. Is this
normal expected behaviour, or another reason to hate the day I decided to buy
a X2 CPU?
P.S.: ANyone got any hard facts on the TSC SMP issues? 2.6.15
is definitely worse for me than 2.6.14, things that used to work just dont anymore.
I just bought a shiny new X2 3800+ and am dealing with all this garbage
as well. Extremely unimpressed with the whole situation in general,
but anyway....
Right now I'm booting my kernel with clock=pmtmr and I've applied the
attached patch to Jack and things seem to be working fine, at least
superficially.
-DR-
P.S. Someone (who I forget) was having problems with Om and every
action taking _seconds_ to produce a visible/audible response. This was
the source of that problem, for the record.
