I've been struggling with this bug for years, or rather with the fact that timebased fx plug ins (Duck, LFO Tools, Shaperbox, ...) and vst instruments with internal sequencers (Maschine, Kontakt Libs) are not correctly compensated for delay. I've described this here many times before. I am surprised that no more people see the scope of these problems. because these timebased plug-ins are extremely important for the modern mix workflow.
