I am thrilled with the huge key editor improvements in Dorico 4.3. If I dream about Dorico’s future, I would love it if it could produce a tempo map for a piece when a user taps the desired tempo either at fixed note duration intervals (eg every quarter note/crotchet or half note/minim) or at marked intervals in the score.
Yes, it would be great to be able to perform the tempo in Dorico in real time. This is something we certainly plan to add in a future version.
