Distinction between ties and slurs
MuseScore, like most other score editors if not all, makes a distinction between slurs and ties between to occurrences of the same note. As far as I know, this distinction doesn't exist in written music. Is there a reason for this? The main drawback of this approach is that when repitching a part, it is common that a tie in the original part (let's say alto sax in a big band score) corresponds to a slur in the second one (let's say tenor sax) because the alto sax plays the same note when tenor plays two different notes. When repitching, this implies backing to the second not (which has changed automatically to preserve the tie) and entering the new note, which breaks the tie. It would be better if the tie was then automatically transformed into a slur.
This is surely not a big deal, but as I have 400 big band scores to enter, it adds up!
