the docs are extremely sparse regarding the IPrefetchableSupport interface.
Google found this page that gave me an idea what this feature seems to be about:
From that page and the header file I assume that it would be a good idea to implement this and return kIsYetPrefetchable in any plug-in that does not depend on external hardware etc., because otherwise Cubase will assume kIsNeverPrefetchable and accordingly exclude the plug-in and the related part of the audio graph from ASIO guard?
What exactly are the effects for an insert plug-in and for an instrument when returning kIsYetPrefetchable? For example, will it be called with larger buffers, or different timing information (in the ProcessContext), etc.? Ayn gotchas we should keep in mind?
Thanks for the clarifications,
