Great news has arrived! Stone System Corporation (Tokyo, Japan) has announced the launch of Chaconne Ex, a music font compatible with SMuFL and Dorico, on 31 October 2024.
Chaconne Ex is the successor to Chaconne. Chaconne was designed for Finale based on standard music symbols used in published sheet music in Japan. It has been the de facto standard for music fonts in Japan for a long time since its launch (in 1996, if I recall correctly). Chaconne was once bundled with the Japanese version of Finale.
The arrival of Chaconne Ex will further accelerate the switch from Finale to Dorico in Japan.
