I guess there is no loop helpers in alsa-lib. You must make your own.

Check how other looping software is doing. I think you could do
something like a function that receives a loop sequence (array of
events sorted by time), a time (or tick) and a max time or max events.

int dump_loop(events[], base_time, max_time);

This function should put the appropiate event from the events[] based
on the time frame and up to the max_time or max_events.

HTH,
