Wow, thanks to everyone for your replies.
One more question - what happens during automation (e.g. in logic)? Is the automated parameter updated continuously during Render()?
For example, if a 'delay time' parameter is automated, and the parameter is updated only between Render() calls, you will get different (smoother) sounding results on a 64-frame buffer than a 1024-frame buffer. I think.

Since setting a 32 bit word (e.g. a 32 bit float) is atomic, no mutex
is needed.
The value of GetParameter could change midway. It isn't likely to
change on a single processor because of the priority of the render
thread, but it may happen on a dual processor.
