You're right, I can do that! I didn't even think of uploading the score. It's quite messy though, a lot of it is me trying to manipulate MuseScore into giving me the sounds I wanted rather than trying to make an actually sensible score.
Right on - the patches you're hearing are actually the solo string patches and not the section patches. I only realized I'd picked the 'wrong' patches after I'd started, but they were focused in a way that aligned with the way I wanted to compose this piece, so I continued with them. I agree that the climax would've sounded super cool with a section patch.
Thank you so much for your kind words, I really appreciate it!
