There is one point in orchestration... It starts in your head and then you are aiming the conclusion of your imagination. Sure, Sample Libraries could bring you to the point, where you say... Thats it...
But the truth is, that you arrange your tracks to get the best, the real result like an orchester...
Today the possibilities are breathtaking... I think, there is today a library for every specific use...
VSL,SFA,OT,PS... and more and more...
And its amazing to work with all these libraries...
But I personally start with a piano and a piece of paper and a pencil... If you only compose for a specific library, cause in this case, it sounds real and wonderful and more... you are doing it, cause of the library, you are using...
And i say no, really no... Cause when i write down my composition on paper...there is it... What i do on the computer with all this virtual orchestras is another thing, but this little composition on paper is more worth, than any super duper excessiv sampling library out there...
And you know what... I like to orchestrate with all the great sample libraries out there... but if its important, i give the notes to every player of a real orchester...And at last what can be more "REAL". than a real orchester with 1 2 Violins,Violas,Celli,Basses...the whole set of brass and woodwinds and percussion...
I know, such sessions are very expensive, but if the budget of a TV,Film and more is there...No regret to use the real deal...
But I love Sample Libraries and i am consumer of all the great orchestral instruments recordings...
To have it at home as a guide for the next steps in production is wonderful....
but remember if you are composing... and being a slave of a library... thats not the goal, i think...
