Don't follow this - LADSPA's control/audio relationship is a deliberate
generalisation of Csound's - LADSPA plugins should be 100% happy working
with krate/arate inputs.

Maybe I'm missing the point too.

OK, your solution is to create a "control" port type and make all its
buffers
be of length one, but I would prefer control signals to be just plain
signals
just with another sample rate. The latter solution allows for connecting
and
converting different-rate (control) ports together, using a resampler
client.
Think combining Csound, where you can select arate and krate by hand, with
LADSPA, where you can't.

Later,
