Ah... this is where we will never agree.
I use samples. Extensively.
I orchestrate and conduct and work with live orchestras. Extensively.
Music to me is about emotion. NOBODY, i repeat, NOBODY gives a crap about any single articulation.
Part of the magic is that sometimes, collaborators will all inspire and influence each other. If you view your orchestra as robots trained to perform on cue exactly your vision of perfection, you will be one very disappointed composer. And a composer without musician friends who don't look forward to playing your work.
I use VSL as much as anyone -- at the highest levels, but never, EVER discount the importance of the hybrid and the collaboration with the real guys. Never.
We're only making music. It's just not that important. Sure, I get notes from fans, "your music helped me through a difficult time" or "we played your music at our wedding and it brought us joy" -- that's a fringe benefit of what we do... but it's never so important that we miss the bigger picture: "does it feel good?"
As a non-film maker, I would never say, "but the DP should have used a different lens for the wide shot... it ruined the film" -- I may leave the film unsatisfied, but the viewer never would call out any technical moment. Unless you're a pro. NOBODY will ever say, "but the viola section didn't articulate the detache's with the snap that VSL library would give it..." that's total bullshit if you think that ANYONE anywhere is actually listening to your music that way. Trust me, nobody cares. Do they like the song? Does it make you feel something? Does it score the scene and make an emotional impact? Everything else is just stuff you do for your own entertainment.
If you truly think that you can make better music with machines -- great. I use the machines as a creative choice and usually financial issue -- machines vs. $30,000 session? Then there are the hybrid scores... so we do whatever services the music. But maybe it's my age, but I no longer believe that anything I do is important. Yeah, people enjoy it. And they pay me. And I get pleasure doing it. And I get pleasure knowing others enjoy it. But if not me, it will be someone else. I am not the only guy who can make a song sound good. So I just do my thing... speaking of, I have 170 bars of orchestration I need to deliver by tomorrow.
