Number of frames in Render()

Hi,

The parameter inNumFrames passed to Render() appears to change very rarely. e.g. on AULab it seems to be constant at 512 and in Live it seems to be constant at 128 if I recall correctly. When exactly does the inNumFrames value change and can it be assumed to be constant between initialisations of an audio unit?

If it can change (i.e. an Audio unit may be asked to render 512 frames, then 128, then 417) what is gained by this in context of the design of the AU framework?

John
