I have to say, this is based on repeated experience. I often avoid updating software/plugins because it often leads to majorly fucking up the sound of a saved project. I usually don't update my Native Instruments Komplete library as a result. Usually I'll do a hard drive image backup first due to past bad experiences. They (NI) seem to have gotten their act together so I'm not as worried about their stuff these days. Well recently I updated my Valhalla Room and VintageVerb plugins and to my utter dismay I opened a project today to finally start working on my music again and hear something off. I find that *every* VintageVerb instance (and I use it a LOT) is set to 100% mix value. Interestingly this doesn't affect the Valhalla Room Reverb plugin. I obviously don't know the mix values of dozens of channels across several projects so this is a major setback for today. I emailed the maker, and I know he's really good with getting back and getting things fixed so I'm not too worried. It just really bothers the shit out of me that every update seems to fuck something up! Anyone else deal with this and have real concern with updating software/plugins because of this kind of thing?
