There is no better stating point
I have to say, this Komplete package lives up to its name. I've been doing virtual orchestration and electronic, ITB production for ten years now. I have collected MANY virtual instruments, sample libraries, and VST effects over the years, piece by piece, to get to a point that I could do really pro sounding work. There is no doubt in my mind, that someone just starting out in this type of production couldn't make a better first decision than to buy Komplete Ultimate.
If you are serious about orchestral production, you will certainly want more detailed and specific libraries in the future but this is a great starter with a more than just the huge Kontakt orchestral library. Now it comes with the Session Strings, Action Strings, and the Session horns which I just used to do a convincing big band arrangement for a webisode.
I have barely grazed the synths but I have used FM8 long before this collection. It is amazing in what it can do. The other synths are crazy deep and full f potential also.
One of the surprises for me so far have been the incredible included reverbs. The RC-24 and 48 are no joke at all. They both sound wonderfully lush.
A quick mention to Alicia's Keys. It is my new favorite VI piano. I have maybe 7 or 8 others and this is my new favorite as a piano player.
Just the things I've mentioned so far basically make this package totally worth the price of admission and there is SO MUCH MORE to see and hear in there.
This is simply the best way you could spend your money to get started in virtual music production and a great supplement to producers that haven't yet embrace Native Instruments.
