Oh wow, Project SAM consolidated their Free orchestra collection into a single library with extras and support for the free Kontakt Player : https://projectsam.com/libraries/the-free-orchestra/
Between this and NI offering the full version of Analog Dreams for free until the 31st ( https://www.native-instruments.com/en/products/komplete/play-series/analog-dreams/ ), if you're looking to get into music and are interested in hybrid orchestration, this might be a good opportunity to get started.
