I have this argument with a good friend of mine all the time - even as recently as a few weeks ago. I said I need more instruments / channels for what I'm trying to do, etc. He says "we didn't have none of this stuff in the 80's, we just made music".
The thing is, if I were to have listened to him since we started having this argument about 12 years ago, I would have one keyboard, I certainly would never have bought the Vienna Library in the first place (what an outrageous expense, and certainly overkill). I definitely don't need the computer I have, without which I couldn't do the projects / mix sizes I do. As a matter of fact, whatever was wrong with my Apple G3 500mhz?! (I do miss the cool blue and white casing I must admit I should have kept it just for that). Oh, and without question I would be still on 16bit/44.1 from beginning to end. I remember that argument like it was yesterday: "you can't hear the difference". I remember another guy saying "Cher's hit single was mixed on a 16/44.1 pci PC interface" "yeah, you can't tell the difference". But I went with my ears and got an external 24bit interface. I upgraded my machine so I could mix in 24bit.
I know of a hit single that a guy did in his basement, literally, with a soundblaster card on a Pentium in the 90's he was famous for it. There are people making it on "Americas Got Talent" jungling stuff and a girl on Britains Got Talent won by training her dog. hehe.
A large portion of professional engineers are now using 96k in the studio. I don't believe it's a marketing gimmick, because I can hear the difference.
And if there's no point to it, why did Vienna spend the extra money to do it in the first place, in a time when it wasn't commonplace, when they released it in 44.1... They obviously thought there was a point to it (and I agree).
Then there's the issue of future proofing your work. Maybe delivery is 44.1 today, in two years, it's 96k and they want a re-release. Easy. There's so many reasons to do it, but the main one is that this is now becoming the industry standard baseline, even if your delivery format is 44.1.
Will I stop using VSL if they don't go to 96k? Of course not... but my reason for posting was just to say, IMHO, *it is time* :)
Anyway, about my friend... my point is, he always says my music sounds great... I never point that out to him.
