the event struct is explicitly defined and its size is constant unlike
other structs in API. thus you can use any allocator as you like,
such as malloc, etc. if the event can be temporary, use it as a
normal type simply like this:
{
snd_seq_event_t ev;
snd_seq_ev_clear(&ev);
...
snd_seq_event_output(handle, &ev);
}
snd_seq_event_output() copies the event instance, so a temporary
variable can be used safely in the above.
