I learned a lot from Mark Shian’s ‘Cubase 11,12,13 Essential Training on Udemy.

Udemy seems to have sales all the time. I think I paid like $15 or so. Wait for the sale.

I also just bought Chris Selim’s ‘Ultimate Guide to Cubase’ with a Black Friday special price. Haven’t watched much yet, but it doesn’t seem to include Cubase 13.

Hope this helps.
