No, "audio rate controls" effectively means you use audio streams instead of function call or event driven controls. Everything's driven by buffers of audio rate data. Controls are just a lot more similar to audio ports.


OK, I see.

I think audio rate controls would be very problematic. In my experience, most controls most of the time are not changing. How often do you use a filter sweep as opposed to a fixed frequency? So an audio rate control would be carrying huge amounts of redundant data. If you then offer an optimization for unchanging controls, you are basically back to the events model.
Also, there is nothing in the events model which says that you can't send events at audio rate.
