For what its worth, the one time I've written code which sends
midi via alsa, the code calls snd_seq_drain_output as last
operation. I don't remember what I did back then, but this
could definitely be the problem. It sounds likely, at least.
static void alsaseq_PutMidi(
struct MidiLink *midilink,
uint32_t msg
)
{
unsigned int d3=(msg>>8)&0xff;
unsigned int d2=(msg>>16)&0xff;
unsigned int d1=(msg>>24)&0xff;
unsigned char buffer[3]={d1,d2,d3};
snd_seq_event_t ev;
snd_midi_event_t *midi_ev;
snd_midi_event_new( 10, &midi_ev );
snd_seq_ev_clear( &ev );
snd_midi_event_encode(midi_ev,
buffer,
3,
&ev);
snd_midi_event_free( midi_ev );
snd_seq_ev_set_source(&ev,midilink->port);
snd_seq_ev_set_subs(&ev);
snd_seq_ev_schedule_tick( &ev, radium_queue, 1, 1);
snd_seq_event_output(radium_seq, &ev);
snd_seq_drain_output(radium_seq);
}
