The only "variable" value is the AudioUnit itself - which I get from
AUGetNodeInfo...
I'm trying to "get" the global property "class info".
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?

So what does -50 mean? Why does it fail *sometimes*? I've tried
the check-for-uninitialized error, call initialize and retry trick

driving me nuts.
From MacErrors.h:
paramErr = -50, /*error in user parameter
list*/
So it's something your passing to the function. Likely your passing
something that is only sometimes valid, so I would recommend doing
some logging around the function that is returning -50.
