True, the score editor does take some musical rules into account, and like I mentioned that accidentals are easily fixable, but the fact that it will put a G# and E-flat in the same chord shows Cubase’s preference for sharps.
Even if your’re working in C major the likelihood of using a G# maj instead of A-flat is slim because it will be borrowed from the parallel minor.
Among all the popular DAWs Cubase has always been head and shoulders above any other in catering for the needs of composers and musicians, with a top notch score editor and unparalleled midi editing and processing functions. Which is why I’ve been using it for the past 17 years.
This is why all the mislabeling throughout Cubase bothers me. Surely if you could setup your project root key to E-flat instead of D# like now, creating the subsequent filter to display the proper notes in the key editor would be less hassle for the dev team.
