I also often use the “Mix as you go” method. I must say however that this is been done to give an general idea how to fit all the parts in.
At the end I often keep the result, but take an additional step by resetting everyting in the mixer and exporting all sound tracks in “raw” state, and mix everyting again in an fresh project. Afther that I decide what comes out best. It’s undoubtetly an more lengthy process, but I often get good results that way…
