Hi,
I'm experienced in C, but am a total beginner to alsa seq api (only been coding to it for a week), and desperately need some help. I'm going crazy here!
I'm trying to create and schedule outbound events, in realtime absolute mode.
When sending these events directly, using SND_SEQ_QUEUE_DIRECT, the events get delivered fine to subscribers.
But when adding realtime absolute timestamps, and marking the event to a queue I've created, only the very first event (time=0) gets sent.
I've struggled for days with the doco, reading example code etc, but am having no success. There are no simple examples that cover my situation.
Can someone please give an overview (or preferably sample code) explaining what I need to do to transmit events in realtime absolute mode?
For instance, do I need to set up timers on the queue? What obscure function calls do I need to make, from the first snd_seq_alloc_queue() call, to the actual snd_seq_event_output_direct() calls sending the individual midi events?
What are the little details - obvious to you experts, but not obvious to hackers new to the ALSA APIs?
I really need help here - I'm tearing my hair out in frustration, and am brain-fried from wading through the thousands of different api functions and macros, and hampered by the lack of detailed doco and tutorial examples (the miniArp example doesn't help, because it's tick-based).
Thanks profusely in advance for your help
Kind regards David
PS - ALSA is really great software. The APIs are very comprehensive. But IMO ALSA could really benefit from the addition of an ultra-stupid-simple-dumbed-down API which covers most basic scenarios, doesn't confuse the newer programmer with 5,347 different function calls and data types, and doesn't require weeks of learning.
