I just wondering how to automate AU plugins. Actually I like to automate the Gain Parameter from Fab Filter Pro L. The user manual say: drop a curve to the plugIn in the corresponding layer. Unfortunately this is not possible (or I'm to stupid to do it). I _can_ drop the curve only before or after the plugin - but then it's a volume automation... dropping _on_ the plugin does not work.
Does anyone have an Idea?
