I'm transcribing the intro section for an instrumental piano piece. The section is about a page long. When I listen to the playback, it sounds good and accurate, etc., EXCEPT at around the 5th measure, it suddenly speeds up the tempo - like double fast compared to the first 4 measures.... I don't have a new tempo-designation here either. Playback seems to just be doing this by itself without prompting. I cannot figure out why it is doing this. It makes no sense.
Has anyone else had this problem?
Does anyone know how to fix it?
