Crescendo is a complete composition tool. It will allow you to not only create scores that are neat, organized, and efficient but it also allows you to listen to them anytime so you can hear how each one sounds.

Crescendo can be used to make arrangements or create new melodies (it even allows you to import existing scores). Crescendo can take any number in the pentagram to get Latin notation. You can also combine voices to choose the beat and measure that you would like to use within your work.

After you are satisfied with a particular section, you can use the integrated midi reader to play the piece. This will give you an idea of the sound it might make without having all the instruments. Once you are done, export your score in any format and print it. This is all free.
