Hi. I am trying to figure out how to make an Audio Unit get tempo and
time position information from an AU host.
in AudioUnitProperties.h, line 470:
// If the host cannot provide the information requested, it can return an
appropriate error
What is an appropriate error? Is there one for "tempo invalid," another
for "beat invalid," and another for "both invalid?"
Also, what is "beat" in this context? I can think of many things that it
might mean, so clarification would be helpful.
By the way, why isn't this just a simple host-implemented method that can
be called and instead it is a declared function pointer type that the
plugin must create and then call? Seems kind of weird and roundabout to
me, but maybe I am missing the point... :)
Thanks,
Marc
