1.2.6 released! - Data folder moved

Important Notices

The most important change in version 1.2.6 is that the default location of song data has been changed from directly under the program folder to the LovelyComposer folder under the user document folder.

It's to facilitate program version upgrades for users. Previously, it was necessary to migrate song data each time the program was upgraded. After this version, you should only have to download the new program.

However, to inherit your song data from ver.1.2.5 or older, it requires manual operation only once. So if you need, please follow the steps below. (Make a backup of your song files before proceeding.)

  1. At first, please boot new version of Lovely Composer app. The "LovelyComposer" data folder will be automatically created under your User Documents folder when the first time boot. (ex. C:/Users/user_name/Documents/ or /home/user_name/Documents/ or /home/user_name/ ).
  2. When the startup is complete, please close Lovely Composer app.
  3. Please overwrite the "music" folder and "app_settings.json"  file in the "LovelyComposer" folder under the user documents with your "music" folder and "app_settings.json" file. (From under the program folder of the previous version LovelyComposer. )

*If you still want to place the data under the program folder as before, it is possible to do so in the settings. (Explanation in preparation)
