I like being able to hear/pick out all the elements in my mix…but that’s not saying they are all to be heard equally. Every track has a purpose…some are prominent and some are subtle…but if I focus my hearing on any one thing, I want to be able to hear it…otherwise, I have to question its value in the mix.
Now granted…like it was pointed out with a full section of violins, you can’t hear them all individually, and you are not supposed to, since they are working as “one instrument group”…and the same thing with layering a half dozen rhythm guitar tracks on top of each other…at some point, they all meld into one global sound…so that’s cool.
But my drums, bass, organ, piano, rhythm guitar(s), leads, vocals…etc…I need to be able to hear them all at their proper level and position relative to the total mix. Yes, you will have some masking…but if like…the organ completely masks the piano, then IMO, the piano maybe should be doing something different, or it should be placed differently…unless of course you are again layering the exact same part with a bunch of different instruments, in which case the masking effect may be exaggerated on some instruments/motes.
