I know of a free plug which will do this, however, I don't think its automatable... I can't remember its name, though I remember it being accessible via the inspector... I'll take a look in my archive and see if I can find it?

I want to create the filter effect in the track, for example for 8 bars. anyone know some accessible plugins, or maybe someone know how to do it in the eq? I have a sonar 8 and ct 8, but in the equaliser I cand do this. Any ideas?
