LOL... to think you will get anywhere near CLOSE to a multi-million dollar film-score production and it's carefully crafted mix by engineers with frickin' Grammy's and Oscar's, for Pete's sake

Sorry, guys, but just about ANY TOTL arranger, used to it's fullest capabilities will get you as close.

That is, nowhere NEAR close!

This quality of production has more to do with the quality of the people playing and engineering it than to the gear they use (which is all incredibly better than any arranger, anyway).

OK, OK, you can get 'close'... But choice of arranger manufacturer won't affect that. Only your ears, your chops and your dedication. And 'close' is going to have to remain a distant second to the real deal.
