I downloaded the latest version from the bandlab website.
I did figure out that I need to save in Midi 1, otherwise you loose 7-8 tracks for some reason.
But then it still fails.
I will attach the original and saved one, and you see that there is 8 KB difference as well.
Also, when I press lyrics on the keyboard, the title becomes "Untitled" instead of the song name.
Managed to get the volume for the main track down to 0, and it was honored by the keyboard,
but when I saved it a second time (since I was testing), it wouldn't honor the volume. so idk if it was just dumb luck.
