my recommendation is that you rethink whatever architecture you're
imagining. you will not, and almost certainly should not, drive a GUI
event loop from anything audio related. you should (IMHO) be thinkng
about two different loops: a GUI event loop driven by mouse, keyboard
and system time(r|out) events, and an audio engine loop driven by the
"clock" of the audio API (JACK, ALSA, whatever). the GUI doesn't need
tight timing (remember that your display almost certainly only
refreshes at no more than 100 times per second, and quite possibly
more in the range of 60-80 times per second.
