First of all, well done in taking the time and willingness to learn in your daughter’s interest.
Few things come to mind:
You can install cubase 12 on up to the devices, so if you had a sister laptop lying about you could fiddle with it too and do the “oh, oh look what I found moments”.
There are a lot of resources for getting started on YouTube. Just literally type in “cubase beginner”, and you’ll get the likes of Dom and Guy pop up.
Learn to drag and drop (or import) songs from artists and play about with adding inserts to see what they do, get used to the interface, get used to the mixer (f3)… Don’t be afraid to explore and press all the buttons, that’s how I learnt, and oh fun fact that a lot… a lot of people don’t actually realise… There is a manual!! Obviously don’t read the whole thing, but a “what’s that do” is very helpful for quick guides.
Have fun and it sounds like you will have great craic between you figuring out this behemoth of a software!!
Are the bars constant? Will it always be 30, 60 120 etc?
If so you could use markers and midi input to jump to. Or are you looking to key in any bar and it jumps to her?
