I am new to Crescendo Music Notation. I imported a midi file and began working on bowings, dynamics, etc. when I somehow got into a mode where I am only seeing one part. The other two parts of this trio aren't showing and I can't seem to get the full score back. Is there a possibility that I hid the score? I poked around enough to be able to take a look at only one of the parts, but don't remember how I did it, and now I can't view the whole score with all three of the parts.
