This issue has been mentioned before as a question, but I thought it would be good to get this formally logged as a feature request.
When inserting an accel/rit that ends on the same beat as a new tempo marking, it would nice to be able to automatically set the accel/rit intensity to match the target tempo.
This could be in the form of a checkbox “match tempo marking” which overrides the standard percentage change dialogue.
If this checkbox is not selected, the accel/rit would follow the percentage change before having an abrupt tempo change at the new tempo marking.
This is a feature that is already available in MuseScore and (if I recall correctly) Sibelius, and would have a significant amount of use.
My main use case for this is when I haven’t quite decided what tempo I want in a new section, but know that I want the previous section to smoothly rit/accel into the new one. It is a pain to have to keep adjusting the rit/accel to match the new tempo.
