changed at *any* time. there is no inherent control rate built into or
implied by the control port. the frequency with which the plugin can
notice the changes is limited *within the host thread that calls the
plugin* by the audio block size, but other parts of the plugin (e.g. a
GUI) can inspect the port at any time.
questions, though. very interested.
