Need some help for a metronome

Hi!

I need some help to get my litle metronome to work. I'm an Alsa-Newbie,
so I'm sorry for this - probably - stupid question. I've copied some
code from tutorials and other Alsa-programs, so probably I've forgotten
some details. But I don't know what.

The error has to be in this function, it gets called every time a "tick"
has to be played, but it doesn't send any MIDI-events. At least,
fluidsynth doesn't play anything (nor prints any events in verbose mode).

- --snip--

void schedule_event( guint8 i_velocity, guint i_ticks ) {
	guint i_channel = 10;
	guint i_note = 33;
	guint i_duration = 1;

	snd_seq_event_t ev;

	snd_seq_ev_clear( &ev );
	//ev.type = SND_SEQ_EVENT_USR0;
	//ev.type = SND_SEQ_EVENT_NOTE;
	snd_seq_ev_set_source( &ev, my_port );
	snd_seq_ev_set_subs( &ev );
	//snd_seq_ev_set_dest( &ev, i_dest_client, i_dest_port );
	snd_seq_ev_set_note( &ev, i_channel, i_note, i_velocity, i_duration );
	snd_seq_ev_schedule_tick( &ev, my_queue, 0, i_ticks );
	printf( "channel: %d, note: %d, velocity: %d, duration: %d, i_ticks
%d", i_channel, i_note, i_velocity, i_duration, i_ticks );

	snd_seq_event_output( handle, &ev );
	snd_seq_drain_output( handle );
}

- --snap--

The printf gets called, and the values are ok. I've also tried the
things which are commented out. Whats wrong, or missing? Can anyone help me?

Thanks!
Sacher
