Hi, here's what I found:
in the track list pane of the score editor I selected my strings tracks because i want to edit them together, but i'm not allowed to record arm just one (for example to work on what i want to write before writing it).
If i do select one i can record-arm it but that means losing sight of the others.
I believe this is a bug or maybe a "non" feature?
thanks a lot to the developers for your hard work.
All the best
