But you're saying that the pre-RenderNotify is the only place I can
schedule parameters. The RenderCallback is too late for that.

For each RenderNotify proc I set up for an audio unit in the graph, the
proc gets called for each audio unit i associated it with. For 2 audio
units with a RenderNotify proc attached to them, the procedure gets
called 4 times - twice before the render, twice after the render.
Additionally, the only way to tell for *which* audio unit the procedure
was called is to use the refCon. Is this correct?
