Good day to you all!
While I have different orchestration books from Samuel Adler, Rimsky-Korsakov, Kent Wheeler and other, I obviously noticed the huge difference between midi and live orchestration. In these books, you'll learn information like the size of orchestras, the anatomy of orchestral instruments and cautions of, for example, not using less than 8 string players which breaks the balance between the string and woodwind sections, ..etc. Information that by all means not necessary in the midi world. In the midi world, you use the 16 violins or the 12 violas patch which clearly doesn't define all these practices. And since I'm an orchestral midi composers, I really found that I don't have to care about all these information.
With that said, I realized more that midi orchestration relies more on orchestration colors through instrumental combinations, nothing more, nothing less. So, I found these advanced books are only useful when they talk about instruments combination to produce certain colors.
As a result, I entirely dumped all these books and bought "visual orchestration" by Alexander publishing that talks about the Spectratone system. This system really proves useful as it clarifies all the info you need in a single chart. Info such as instruments ranges, the modern registers, the color of each range, the combination possibilities between instruments' colors, each note frequency and more. As a midi composer, I personally found this chart as the ultimate my go-to system for proper and quick orchestration and it's printed on my studio's wall.
