Hi there,
I'm wondering what the pros and cons of buffered vs. direct output of
sequencer events might be.
As far as I have found out, snd_seq_event_output_direct has the
advantage of not having to care about calling snd_seq_drain_output. On
the other hand, snd_seq_event_output allows the removal of scheduled
events via snd_seq_remove_events.
But I am sure that there are a number of other arguments...
Thx,
Gerald

If you want just to send events immediately, there is practially no
disadvantage of using direct output. The buffered outputs are
basically designed for scheduled events.
