If I leave the plugin window open (natty, calf plugins from repo, alpha5) I do indeed see the cutoff moving as desired. I have the resonance turned right up but still I cannot hear any noticeable change in the sound. However, if I move the cutoff slider manually during playback it works as expected. Hmmm! Paul's big natch for alpha 8 was noting that MIDI CC (yes, I know, but undoubtedly this is closely linked) is still quite borked so maybe this will work as expected come alpha9?
