Finale 2011, audio done directly in Finale, using various plugins, without exporting anything to Cubase or similar.
Libraries used: Berlin Woodwinds for woodwinds, Cinebrass for brass, East West for percussion and LASS 2.0 for strings.
Mastering plugins: Ozone 5 for EQ, Harmonic exciter, Compressor (just a touch...), Stereo image; Reverberate (rich hall) to create the ambience.
The difficult thing is that the various libraries used are recorded in different environments and LASS is dry, so on the strings I had to apply a Kontakt 5 reverb preset and then the general reverb.
The total weight of the software and various plugins is around 3 GB, so even with a 32-bit system it's doable, but I optimized the Kontakt buffer to the maximum so that the RAM used in loading the instruments would decrease; otherwise, you exceed 4 GB. This is possible by having an SSD (solid state drive), which is very fast at reading.
It goes without saying that I made countless attempts and comparisons with demos and tracks from real orchestras found online; I also found some truly interesting virtual orchestration lessons and it seemed to me to understand that a lot depends on the ear and the experience gained over the years, while the libraries are what they are—the best ones around are those (EW, LASS, Vienna, Cinematic Strings, Cinestrings, Berlin, 8Dio), there aren't any others; when we listen to a demo that sounds monstrous, it's because there is a sound engineer who knows how to bring out the best from every single library.
I own all these libraries except Vienna, so I can say that my choice for strings fell on LASS for timbral reasons and RAM usage; Cinematic Strings are too dark for me, 8Dio Adagio presents quite evident sampling errors, I don't have the Hollywood series from EW but the previous one, which in terms of quality is inferior to LASS, but Hollywood is extremely heavy.
The only problem with LASS is that they are dry, so you have to tinker to create an ambience even before you start composing.
