What are the procedures to download CDGS into the Karma program?
If you have the files on a certain partition on your PC, then open the application and go to Menu > Media. Click Add Folder and mark the folder where the media files are located. I have tried other file formats, but it should work with the CDGs as well.
If you don't have the software, access the following URL to download a trial version: http://www.karaosoft.com/productdetails_karma.aspx
