Hi Clemens! This applies only to note events, not to note on events. Note events are split into a note on and a note off event. Gotcha. That is what I meant. :) int queue = snd_seq_alloc_queue( our_parcel->seq ); You must create the queue before you try to send events through it. I attempted this which still does not work correctly. >>> indicates changes. //Queue snd_seq_queue_tempo_t *tempo; >>> int queue = snd_seq_alloc_named_queue( our_parcel->seq, "Q1" ); snd_seq_queue_tempo_alloca( &tempo ); snd_seq_queue_tempo_set_tempo( tempo, 1000000); snd_seq_queue_tempo_set_ppq( tempo, 48 ); snd_seq_set_queue_tempo( our_parcel->seq, queue, tempo ); >>> snd_seq_start_queue( our_parcel->seq, queue, NULL ); snd_seq_ev_clear( &event ); snd_seq_ev_set_source( &event, our_parcel->out_port ); //snd_seq_ev_set_subs( &event ); snd_seq_ev_set_dest( &event, dest.client, dest.port ); snd_seq_ev_schedule_tick( &event, queue, 0, 20000 ); snd_seq_ev_set_note( &event, 1, 67, 127, 800 ); Note, that above I have tried both using subscriptions and directly sending to the destination port. Neither works correctly when i am sending the alsa event to another process, but snd_seq_ev_set_dest() does work when sending to another port in the SAME process/client. I verified this using another thread listening on the 2nd port. Pretty odd. Finally, I output the event and drain the output... >>>snd_seq_event_output( our_parcel->seq, &event ); snd_seq_drain_output( our_parcel->seq ); I've read thru a couple of small programs now which seem to do just this but actually work. Any idea what i am missing? thanks a bunch , -paul |
