The main changes are bug improvements in operation and save, and addition of copy / paste function! (Earlier versions often failed to save data! (I'm sorry for those who tried and saw bug))

Some advices is below.

• "myjson.json" is data file of all songs, if already you created your song by this tool, you can overwrite the file to import your songs.
  
• If you using track part 4 in your music, and its on the play, and when ringed sound effect, part 4 play is stop. This is the current library specification and will be fixed in the future. If you cannot hear the sound of Part 4, try playing it again.
• Now you can use short cut key, copy & paste: CTRL+C, CTRL +V, and others. Please see guide message on the tool bottom line.
• To the right of the paste button is a single layer / all layer target switching button. It is effective for the copy function.

Enjoy! And tweet a video of the song you made! 👀 #LovelyComposer
