The cursor moves in the opposite direction during playback! That is, from right to left. You need to re-enter the editor several times for the error to go away. (You need to record this video. But I am a composer, not a video editor.)

The theme is designed according to the rules. Except for audio data, which is not in the project. And there are no problems with playing MIDI notes either.

Well, with words, I was not lucky. Used English and constant crashes. I had to use the lyrics to clarify the arrangement. But in this case, how now to bring in the real lyrics of the song if needed? I tried to run safe mode, but the result is the same. There are no audio plugins in the project, there are no midi plugins either.
And what about the “stuck together” notes? Restarting the editor fixes this problem. But you need to go to the MIDI editor, which constantly makes the score editor run twice?
