CDO - Crescendo Music Notation File

What is a CDO file

The Crescendo Music Notation Editor – a program for writing musical scores – creates files that use the CDO extension. It’s commonly known as a music file. The file contains different kinds of information about the music, such as meter, notes, and even page layout information that is used when the score is transformed into sheet music.

The CDO file format is exclusive to the software developed by NCH Software. It is commonly used to save arrangements and compositions that make up a music score. Since the format is quite rare, users also have the option to export their music in the more common MID format.

Here's a small, but not exhaustive list of programs that can open CDO documents:
