This is difficult I think to word this more directly because what is “equal”? It depends on what people are doing and what they are needing. It might be more accurate to say to get the types of customization options for scores that you had in C13 you must export to Dorico. Because in terms of default spacing and layout, it is hands-down better, and the default appearance of Cubase 13 (and earlier) scores is a major issue and for me an untenable timesink to manually move everything on the page around (every single note and every single other object) to get it looking half decent. At the same time I understand where people are coming from in not wanting to separate DAW from notation quite so greatly.
My background is that I started off mostly as a self-taught composer and then began to take composition lessons and went back to university to study composition properly. I started as a teenager with an old program called Musicator (which doesn’t exist anymore) that combined piano roll and notation into one. I stayed on it for a very long time (comfortable with it and unwanting to change) and only finally grudgingly moved from it in 2006 to Cubase 4 when I realized it was starting to limit me.
About a year after that I started to take music composition and orchestration lessons privately. I tried to do my work in the Cubase 4 Score Editor but my teacher told me it was all terrible and basically made me buy Finale. This was a significant improvement in the appearance of my scores but started me on a path of being very frustrated at having to use two different programs instead of one unified music program - DAW vs notation and never the twain shall meet.
I made one other big attempt to use the Score Editor a few years later in 2012 when I was working on my first orchestral work that was to be performed, and I wanted to write it with my sample libraries in Cubase but do the final score in Sibelius (which I had moved to from Finale by that time). So I did a temporary score in the Cubase Score Editor, adding display quantize everywhere, and finally exporting it and bringing it into Sibelius. It was a huge amount of effort and at the end I’m not sure it was really worth it. I had to do hacking of the XML I recall to bring in the tremolos properly because Sibelius imported all the three-stroke tremolos as one-stroke. I also recall lots of manual work with the trills. At the end of it all I might just as well have renotated it in Sibelius by hand - it would have been less work.
There was one other student who started his undergrad at my university using the Cubase Score Editor. He was big on it from what I recall and felt like he could do anything with it. By the next year he had changed to Sibelius - I didn’t get the details, but I can assume due to pressure from his professors who could see that his scores just didn’t have the same polish as those of the other students. Unfortunately the presentation matters. In academic settings you are expected to have polished scores, and your peers do. It looks quite badly if you are the only one who doesn’t.
When Dorico came out (and I moved to it), one of the things I was most excited about it is that I thought finally, this is something that can bring DAW and notation together again, so I could reclaim what I felt I had once before with Musicator and had lost. And it has actually done that in most respects, with full piano roll editing in Cubase style and CC’s, just missing the ability to work with audio tracks and things of that sort, and automation capabilities.
My point of all those is from my perspective, it was as though Cubase never had a score editor before Cubase 14. It did, theoretically, but it just was not anything that I could use in actuality. The default formatting was just not anywhere near good enough, and if I start having to move around every single element on the page by hand, it becomes untenable. I just don’t have the free time to do that. So anytime I would write things in Cubase (13 or earlier) that would have to get performed I’d manually renotate it in Dorico, rinse and repeat. But now I don’t have to do that. And the default formatting done by the Dorico engine is good enough that if I need to print a quick part and it is something simple, I might be able to do it entirely from Cubase 14 without having to apologize for the result. I could not say the same of Cubase 13 and earlier versions (at least, not without putting in much more work than I would be willing to do).
