The results of my search of this forum for comments on this subject didn’t return anything that, so far as I could tell, directly addressed my question.
I will be using Dorico primarily for composition and playback.
I would find it a very useful capability if, while in Write mode, I could select a location on a staff and via keyboard audition the instrument currently active on that staff without entering any notes. I could play a line to see how a prospective line for the sound works. (This capability exists in my previous notation software.)
In Cubase I can audition a track on my keyboard, So I can try out an idea by playing along with what I have composed so far. This would be a quite helpful feature.
