Hello, this is Musia.
In Musia One Basic mode, when loading a project prior to version 2.9.3, the error that caused it not to load properly or the web to crash has been fixed. Please refer to the details of the error fix below.

[Before the error fix]
- The error screen is displayed and it works abnormally
- The error where all the chords in the chord progression are overlapped as a whole chord

[After the error fix]
- The project can be loaded normally
- The chord progression is displayed normally

We apologize for the inconvenience caused by the error, and Musia will work harder to provide a better service.
Thank you.
