[linux-audio-dev] LADSPA plugin parameters realtime control

[Iain Duncan]

If you consider the buffer size to be the control rate, then that makes 
sense. You don't want to be updating control information as much as 
audio information if you want things to run at all quickly. Ie, and lfo 
just doesn't need to be audio rate unless it's being used for fm or am 
or really high freq stuff, and knob/slider tweaks certainly don't!
