By doing this in the render notify, you are doing this on a high-
priority thread with a strict deadline - You are setting the state of
an AU, and it really isn't defined how much time this property can
take. So I'd not do this on the I/O thread.
Can't you set this before you call AUGraphStart?

wrong about this stuff before. :-)
This solution has additional benefits because it doesn't block the
UI thread when configuring units - so it "looks" like the app is
faster because the UI updates sooner even though the notes don't
work for about another beat. Since it is a live performance app
and this happens when you are switching songs, this is totally not
an issue.

I'm shooting from the hip, here, but it just seems wrong to handle
this in the render notify. Isn't there a notification specific to
AUGraphStart that you could use instead?

I ended up doing what I said - setting the state within the first
render notify callback from AUGraph. Seems to work reliably.

Definitely looks like some kind of race condition - I've just
called AUGraphStart and now I'm trying to plunk in the states for
the virtual instruments. Is AUStart asynchronous? Should I set
a flag and do this in the first render notify callback?
