What is a .IGR file?
The .IGR file extension is used for a type of file called a Quest3D Channel Group Layout File. However, this description seems to be a mix-up. Actually, .IGR files are associated with Igor Engraver, a software that was designed for creating musical scores. These files contain musical notations, which means they store information about the notes and rhythms that make up a piece of music. They also include details about the musicians and instruments involved in the composition. Essentially, .IGR files are used to save musical compositions that can be played back or edited within the Igor Engraver program.
Unfortunately, the software called NoteHeads Igor Engraver, which is used to open these files, has been discontinued. This means it's no longer being updated or supported by its creators. Despite this, the program can still be used on both Windows and Mac computers to open .IGR files. However, there's a small catch for Mac users. When saving .IGR files on a Mac, the file might not show its ".igr" extension. If you want to use these files on a Windows computer, you'll need to manually add ".igr" to the end of the file name.
It's important to note that the version of Igor Engraver for Mac was made for Mac OS Classic, which is an older operating system. This means that if you're using a more recent version of macOS, you might have trouble running the software.
