| Hi everyone, I am having difficulty getting alsa to actually delivery a noteon event for me. I am came across a list posting from 2004 which claimed that Queue's were necessary for NoteOn's to allow alsa to schedule the concomitant Noteoff at the appropriate time. Nevertheless, i can find nothing in the documentation which collaborates this. Still, i did attempt to use to a Q but was unable to produce any results. Here is the offending code: snd_seq_ev_clear( &event ); snd_seq_ev_set_source( &event, our_parcel->out_port ); snd_seq_ev_set_subs( &event ); //subscription was graphically verified with Qjack snd_seq_ev_set_direct( &event ); snd_seq_ev_schedule_tick( &event, queue, 0, 4 ); snd_seq_ev_set_note( &event, 1, 67, 127, 8 ); //Queue stuff snd_seq_queue_tempo_t *tempo; int queue = snd_seq_alloc_queue( our_parcel->seq ); snd_seq_queue_tempo_alloca( &tempo ); snd_seq_queue_tempo_set_tempo( tempo, 100000); snd_seq_queue_tempo_set_ppq( tempo,64 ); snd_seq_set_queue_tempo( our_parcel->seq, queue, tempo ); snd_seq_start_queue( our_parcel->seq, queue, NULL ); snd_seq_drain_output( our_parcel->seq ); Any help would be much appreciated. thanks in advance, -paul |
