The only further processing that I like to sometimes perform after mixdown and mastering mode, is sometimes I like to do another copy of my songs with a fade towards the end of the song; and like pretty much every other task, I do so by just bouncing my tracks until I have only one final, completed track remaining in track mode before entering into mixdown mode. It's my technique for recording with these systems. In order to do that with an already mastered song, can I just go into track mode, do another bounce with my fade, and then reenter into mixdown mode to do another mixdown? If so, since I'm attempting to avoid glitches, shall I just delete the z file and master file first using my computer prior to reprocesing my final bounce track in bounce mode and then running it through mixdown mode, etc., or is deleting the z file and master file first not necessary in order to perform this task?
