As usual, raino has spot on advice, in this case re: the vids.
Maybe the best ones to look at first are the “Getting Started” ones in the “How To” collection.
Even if the Cubase version they are talking about doesn’t match yours, I think they might be a great help nonetheless.
Also, in youtube, searching “Cubase for beginners” brings up a few promising-looking vids, even one for Cubase 11. I haven’t listened to them, so can’t vouch for their quality, or even accuracy (!), but i bet they’re pretty good to get you started.
It does take time to get to know Cubase like any other daw. It gets easier and more fun as you learn new things.
As others have said You Tube is really useful
Here are some of my favourite channels.
“Cubase” - look for some of the beginners videos.
“Music Tech Tuition”
“Jeff Gibbons” has a good Intro to Cubase series
“Frank Rapke” has some great videos on keyboard shortcuts amongst others and I find that his videos are paced really well.
Start learning the very basics of recording and editing first. Familiarize yourself with shortcut keys and everything that can enhance your workflow during recording and editing so you can step through this effortlessly. Don’t try to understand everything you see and can open in Cubase. Try to focus on what it exactly is you want to achive and focus on the skills you need to develope to achieve this. Don’t let yourself get distracted and discouraged by the though you are missing out on all these other advanced features you don’t understand yet. I’ve used Cubase for decades and there are still a lot of things I have yet to fully understand and master. And that’s mainly because I don’t really need these to achieve what I want. Always remember, the goal is not to understand everything that Cubase has to offer. Cubase is a tool to help you achieve your creative goals and IMO the best in this area. If you can do this and feel comfortable working with it you know you’ve arrived where you want to be. And there is still more than enough opertunity in Cubase to broaden your horizon of skills even further if you feel the need.
And like said before by others here, Cubase has a very steep learing curve so visit YouTube and watch the various instruction videos by Steinberg and other third parties. You will also have to permit yourself plenty of time to grow into it. But I can tell you from my own experience that it’s well worth the time and effort.
Hang in there. Trust me, you’re not alone. I have some history with Cubase but it still confuses the heck out of me. I’m just a weekend warrior and play around with it for my own enjoyment. I’d say I only understand about 30% of what it does and how to use it. You will need to invest some time. I usually just start a song and when I get to something I’d like to do and don’t know how to do it I just do a search, maybe ask a few questions here and proceed. I may spend 2-3 hours just trying to figure out how a particular function that I need works. But in the end you’ll really feel like you’ve accomplished something. Hang in there.
