Oh dear lord. Well, I downloaded Finale. But I guess this means that every articulation from every past file is borked? This is a bad day.
By "tempo expressions", I assume you mean when you put a tempo marking at the beginning of the piece. I have done that, and set it to quarter = 64. It plays it that speed when I click playback, but...
Yes, but how do I get the MP3 file to save itself at the correct *tempo*?
