Ok I was just taking the photos, and I fixed the problem. The Aeros has a programming error, a bug. But I know what the bug is.
1/ If you use the pencil shape to edit a song to turn on click it doesn’t work, even if you didn’t record anything. So the default song… song_1 can’t be edited by the pencil. you can see the settings, and scroll down, and change them, and save them, but they don’t work after you change them.
2/ However if you use the + sign to add a new song then you can turn on click setting.
So basically I never clicked the + sign before.
So something is wrong with the pencil that isn’t working properly.
