Here’s a great tutorial from composer Michael Patti and Cinesamples, wherein Mike creates an orchestral action cue in 8:57. He doesn’t mention what sample libraries he’s using, but I can only assume they’re all from Cinesamples since they’re sponsoring the video. The video is a lot of fun and highly educational to boot.
Thanks to Film and Game Composers.com, where I originally saw the video.
Edit: Patti does mention one of the libraries he’s using. The trumpets are from EastWest (I’d imagine from EastWest Symphonic Orchestra
). And for those curious about the octatonic scale (also called the diminished scale), there’s more info here.
