NI Guitar Rig can update parameter list in Logic9 dynamically, what about a Juce plugin?

Hey Jules I'm sure you're reading about plugin parameters everyday but still:

In Logic 9, when I change an effect rack of a NI Guitar Rig plugin, it does updates the parameter list ( names of each param, number of increments etc...) of the instance dynamically.

That's exactly what i would like to achieve with my Juce plugin.

Any idea on how to do that with Juce? Is the behavior different between AU and VST in this case? 






If anybody's still looking for an answer to this, use AudioProcessor::updateHostDisplay(). See
