I'm an amateur composer interested in purchasing a high quality orchestral sample library like Garritan Personal Orchestra. The problem is that I plan on composing a piece for my schools concert band, and I can't decide between Garritan's "Personal Orchestral" or the "Concert & Marching Band" sample libraries: https://www.garritan.com/
I am in the process of reading Rimsky Korsakov's "Principles of orchestration", so it would be ideal to have a high quality virtual orchestra. I would still use the concert band library for other projects, but I plan on pursuing film/video game composing as a career, and these typically use orchestral sounds. I also just enjoy orchestral music more in general.
Advice from composers/musicians who have experience in both the orchestra and concert band would be greatly appreciated. Do most of the orchestration principles apply to both groups? Would writing one concert band piece while learning orchestration for the orchestra be confusing. Thanks in advance!
I also play the clarinet and alto saxophone.
