Hey bitch.
Welcome to the madhouse
If you back up all of your patches into your computer then you don't have to worry about what you overwrite as you can always recall it later.
I would say that alot of the problems you are having would be solved by using a patch editor/librarian like Soundiver. I usually save the 'state of the virus' before starting a new song. If I'm going to be working on a DnB track, then I'll load lots of DnB soundsets into the virus using Soundiver and then get to work. If I want to get back to where I was, I just go back into soundiver and reload my 'state of the virus' save.
Hope that helps bitch!
