I understand all of this.. but the original post had talked about
generating these events... In my view it should do what it always
does... This API is there for the host to manage the interaction as
Nikolaus explained.
My impression of why we added these APIs was so that the user's
interaction was captured by a host. But that the UI or the AU itself
would NEVER need to generate these - that parameter notifications were
provided for that messaging

and then create an automation notification with this time stamp. It

unwise to rely on the accuracy of the mouse event time stamp, or to
delay until
the notification is received. Note, I'm assuming that the mouse event

has a time stamp field.

Of course, the notification or other message would need to
have the time as a value, and a flag to indicated start or
stop (unless there
are separate notifications).
Well, the "time" would be the current time when the
notification was received, right? Although I suppose it might
be off a sample or two from the original trigger time. (In a
bad case.)
Well I agree with Brian since it would be better IMHO to had
some more time stamping to the notification scheme (allowing to
have more liberty in the way to propagate the notification).
I'm thinking of related problems that I encounter with MIDI,
while receiving simultaneous NoteOn and NoteOff, with same time
stamp...
