The host may wish to provide a representation of data entering or

Note that these are only hints. The host may ignore them and the
plugin must not assume that data supplied to it is meaningful. If
the plugin receives invalid input data it is expected to continue
to run without failure and, where possible, produce a sensible
output (e.g. a high-pass filter given a negative cutoff frequency
might switch to an all-pass mode).

input control ports are expected to be particularly useful.
