There’s a good selection of material in this thread:

What is your best material to recommend to learn VCV Rack2

Hello, people, I’m studying VCV Rack 2, Modular Synthesis, Electronics, Programming… and all the things we know are cool and necessary to learn. So: Let’s use this space to share didactic material, documentation, videos, links, etcétera. Cheers from the jungle. Ø

I can recommend Roland’s “The Synthesiser” set. More info in my post in the above thread.
