I changed the time signature in a piece (from 12:8 using eighth note subdivision to 12:8 using dotted quarter subdivision), and all the dotted quarters were replaced with tied quarters and eighth notes. The only way I have found to correct them is to delete the tied notes and insert a dotted quarter. Is there a way I can fix this problem in one fell swoop?
A related question: I tried entering the dotted quarters on top of the tied notes, i.e. to replace them, and Finale would not allow the replacement. Is there a setting that needs to be changed? Sometimes it works to replace existing notes with notes of another duration, and other times it doesn't, and I haven't found a clear explanation.
