An undo history that’s local to the event, rather than global. Of course you get the same benefit using automation, but compared to for example Pro Tools’ “Audiosuite” this is a benefit.
just add the plugin to Inserts chain, disable it and with automation enable it wherever you want.
if it is a vst3 it wont consume resources while disabled.
I don’t. As a reminder I’m using Nuendo and do audio-to-picture. But anyway, I just don’t see a need. If something doesn’t sound the way I want it to I’ll typically remember what I did to it or just open the DOP window to see what’s going on, if anything.
Typically I use DOP on dialog mainly for cleanup (iZotope), pitch shifting and so on. EQ, reverb from sends, compression etc. is all on inserts.
