Perhaps I have not fully understood how it works, but… I need your help, dear colleagues. When I switch on the “insert” mode, I use the command to double the durations. Everything seems to be not bad in terms of rhythm, but the signs of dynamics are not bound to the durations, and there are so many of them that I decided to ask local experts how it can be tightened without labor-intensive costs. Thanks in advance. If there is no such possibility, perhaps programmers can realize it in future versions. Regards.
I do not know whether that is a given or whether using the System Track (ALT/OPT + T) to select everything would work better.
AFAIK this is how double/halve duration work. The dynamics, tempo changes, etc., are linked to a specific rhythmic place in the score, not to specific notes. Everyone sees how unhelpful it is in this situation, but I guess the Dev team have been weighing the pros and cons before they implemented this.
In any case, until doubling/halving tuplets as well, these tools won’t be as effective as they seem to be
