I use a hybrid where ports are audio-rate AND each port has two states: 'streaming' or 'static'. So if you don't want audio-rate modulation, you pass a buffer of identical values and set the port state 'static' (not changing). The advantage is: 'Dumb' plugins need no special-case code, just write them as though the port was always audio-rate, one single simple code-base. 'Smart' plugins can query the port state and switch to more efficient code when the port is 'static', e.g. read only the first sample, treat it like a block-accurate parameter (i.e. Far more efficient).
