Hi, 

i don't know whether you want to send midi events directly or schedule
them via alsa_seq. If the former case have a look at my small test
programs in this tarball

http://affenbande.org/~tapas/midi_timer-1.tgz

There's two programs in that tarball, one using the RTC for timing and
the other using the system timer and usleep() (the RTC based one does
achieve better accuracy).

Both programs simply try to send a stream of note-on events at very
regular intervals.

If you want to use alsa_seq's queues to schedule events for delivery at
a later time, you probably might have a look at rosegarden.

Have fun,
Flo
