Ok so what happens if I've changed some plugin settings on a new project.
Then next week I decide to bring up another project which is the final mix of a project I was working on last year. Just so happens I'm using the same plugins.... Will I have lost my mix?
Depends on whether using upsampling makes a huge difference in the sound. So I think what you're asking for is a "disable all upsampling" button, right? Only problem with that is if you forget which plug-ins really benefit from it...so maybe what you want is presets of which plug-ins do or do not resample.
However if your experience is like mine, you'll find it's needed for a limited number of plug-ins, and the improvement in sound quality will tend to make you want to leave it on once you've identified "suspect" plugs.
Another scenario...
I'm working on Sonar at Abbey Roach studios today using Sonar. Fred is using the same studio tomorrow and inadvertantly changes the settings. We are working on seperate projects. I'm back in the studio the next day...
Well, that's an easy one: tell Fred to keep his effing hands off your computer.
