Here's the pseudo-code of the relevant MIDI player routine:
for (i = 0; i < number_of_events; i++)

usleep(event[i].delta_time_in_microseconds);
output_and_drain_event(event[i]);
}
This routine gives a non-bearable latency on 2.4 kernels but not so much on
2.6

Why?
Because the queue output and draining, AFAICS, is implemented in a blocking
manner. When events are being played by the queue in the kerne

Hi,
(1) I've written a command line MIDI sequencer for lightweight systems and
am successful in making it work using the ALSA queue API. However, one
drawback of the API is its lack of callback functions. I wish to be able
to track events as they are drained by the queue.
(2) I know and ha
