Confusion on the Bee Gee's thread has prompted me to post this. Let's be sure we understand the difference. ------------------------ Master tape vs. multi-track tape vs. mixdown tape: In general I feel mixdown is a modern word that really clouds the issue. A MASTER is what it is: A tape that is the final finished version of a song or group of songs that can be "mastered" on to a disk and marked as such. A master can be mono, stereo, etc., mixed from something or the original mono or two track tape or a final dub with echo or whatever. A multi-track tape is never ever called a master. A multi-track tape is not finished. It is unmixed. It is not a master until it is mixed (called "re-recording" in the movie business or a "reduction mix" in the Golden Hi-Fi age terminology) on to a new tape and set in stone. The actual word mixdown tells us nothing. Why? Simple: A mixdown could be a rough mix, a mix without the singing or the conga drum, a mix without the background vocals, etc. A MASTER is what the word sounds like.
