I’ve seen over there some editions that use a parenthesis-styled non-arpeggio symbols (as shown in Image 1) rather than the squared-styled one that Dorico uses with Bravura. Could there be an Engraving option to decide which is preferable?
I’ll make a note of this, Albert. It seems like a less satisfactory appearance overall, given that it takes up more space than the bracket. Do you know which publishers or composers in particular use the curved variant?
You can take a look, for example, at the first page of “Antiche danze et arie per liuto”, Suite No. 1 (Ottorino Respighi) —lower staff: http://hz.imslp.info/files/imglnks/usimg/8/88/IMSLP16124-Resighi_-Antiche_danze_ed_arie(trans.Respighi-_piano).pdf.
