hm.. i would like to make simple example of scheduling few midi notes to queue and alsaseq where the length of the loop will be one bar or any number of ticks...

i'm kind of stuck :(

i got two midi notes triggered (event & event2) but don't know how to play the queue again or in loop while notes which are already there should be played in every repetition...

i'm trying to do that placing alsaseq.SEQ_EVENT_SETPOS_TICK at 0 (or 1) but it doesn't play the notes again...

my logic is to schedule the playhead of queue at the beginning after some number of ticks and i assume that already queued notes will be there.. i'm quite sure i'm wrong ;)

what would be good logic to do that?

do i need to leave queue alone and implement my own logic on top of it? something like adding notes all along the timeline simulating the repetition that way... i would like to know or to check what's the tick of running queue.. do i do that scheduling alsaseq.SEQ_EVENT_ECHO some place on the timeline? hm... lot's of questions... hope someone would explain to me a bit of the alsaseq inner logic... i'm sorry i couldn't find good documentation but testing the library inside ipython....

here is how my session looks like (i connect "myPort" to Virtual Raw Midi with a little help of qjackctl and monitor it with amidi -p hw:2,0 -d):

from pyalsa import alsaseq

seqsen = alsaseq.Sequencer() seqsen.create_simple_port("myPort", alsaseq.SEQ_PORT_TYPE_APPLICATION, alsaseq.SEQ_PORT_CAP_SUBS_READ | alsaseq.SEQ_PORT_CAP_READ)

queue = seqsen.create_queue() seqsen.start_queue(queue) queue = seqsen.create_queue() seqsen.start_queue(queue) tempo, ppq = seqsen.queue_tempo(queue)

event = alsaseq.SeqEvent(alsaseq.SEQ_EVENT_PGMCHANGE) event.queue = queue event.time = 96 event.set_data({'control.value' : 127}) seqsen.output_event(event)

event2 = alsaseq.SeqEvent(alsaseq.SEQ_EVENT_PGMCHANGE) event2.queue = queue event2.time = 96*4 event2.set_data({'control.value' : 100}) seqsen.output_event(event2)

event3 = alsaseq.SeqEvent(alsaseq.SEQ_EVENT_SETPOS_TICK) event3.queue = queue event3.time = 96*5 event3.set_data({'queue.queue' : 1}) seqsen.output_event(event3)

seqsen.drain_output()

## event and event2 being sent but event3 is unnoticeable to me...
