More uses: * Vibrato/Tremolo (sounds better with continuous control) * Fast transients (percussion synthesis) * Smoother response to erratic input (smoothing the output from a gui widget makes for a nicer 'feel') In short, I support the addition of this hint to LADSPA :) > > There's a syntactic ambiguity in the name AUDIO_RATE_CONTROL.

Maybe a different name > (CONTINUOUS_CONTROLLER?) would be clearer. Seconded. I think including 'AUDIO' in the hint would confuse matters. A short comment in ladspa.h could specifiy that 'continuous' means 'at audio rate'. Mike __________________________________________________ Do You Yahoo!?
