Well,

By looking at the LADSPA system, I was taken of surprise by something: is
there no buffer for control bytes? I mean, if I want to process one frame
of audio sample with, say, a volume control plugin, but I want that the
value of the volume control changes during the whole frame, with a
sinusoid for example, how can I do that? Shall I set the frame size to 1
and change my control for each one-sized frame? I'm a bit dazzled with
this one...

One solution I found was to "sample" my sinusoid and, for each frame,
giving only a constant control byte that was sampled from the control
frame. But I'll loose precision...

Any idea, comment, precision?

Thanks
