Bonjour Pix,
Generaly speaking, it seems that AudioDirector as host application, does not manage perfectly the presets of VST plugins.
I have also Izotop Vynil (of course old VST), but still fully operative (with presets) in some host application as SoundForge.
No presets are available in AudioDirector. To test, I have imported other plugins, It is idem for the free VST KarmaFx etc ...
Perhaps, would be well to take th opportunity to propose an improvement of AudioDirector for a full management of VST plugins.
You are a specialist, what do you think ?
