Hello, I just downloaded ScoreCloud 4 and I am using it to isolate a certain part of a song. It's just a snippet, but the mp3 file is 4 minutes and the program won't do a song longer than 3. I only need a short part isolated to analyze, but I can't figure out how to select and snip. I looked through the manual, tutorials, and FAQ, and I still can't find that information. Thanks.
