I found Jeff Gibbons particularly helpful. Step by step “let’s make a song” intro to the cubase sound environment. Dom Sigales is great as already mentioned. Interface gets sound into the computer ( scarlett, steinberg, and others), microphone and keyboard connects to that get sounds on to a track. Headphones are fine to start. Follow Jeff Gibbons’ step be step process and you will be getting a good start. Have fun and don’t worry. You can’t break anything.
It’s no longer “CNTRL+ ALT + SCROLL” ?
