Entirely possible that one of the song grids is inaccurate... have you checked them?
Some tracks are not syncing properly on WeDJ for android.
Thank you for the reply. Yes I checked it, and you're right the problem is that the grid is not accurate. I know how to access the grid editing, but I don't really understand how to use it. For example when I set it at the beginning of the track then it sounds good, but at the end of the song is again become inaccurate. Can you help me please? Or is there any tutorial about this somewhere?
