I recently upgraded to Cubase 10.
I use Midi step input- record pitch very much, and in Cubase 9 it was much easier.
It was just turned on all the time, and I just selected the notes and I could move them around in pitch.
In Cubase 10 I have to turn it on, press the note, turn it on again!!!
Is it a Cubase 10 problem or do I need to set something somewhere?
Hm… I checked that- it’s something I use a whole lot too. Here, the setting is remembered.
With that in mind my suggestion would be to start Cubase in safe-start mode by holding ctrl-alt-shift while Cubase launches, and disable prefs to see if the problem persists.
