OnSong Manual


If you have lots of paper chord charts, you may opt to scan those documents into a digital form. One method you could save files is as a JPEG image. You could also use JPEG images for lyrics projection backgrounds. OnSong can import both file types and determines their use automatically.


JPEG images are typically used for photography since the compression algorithm can be used without noticeable loss of quality. However, as the compression is increased, the artifacts may become apparent and the image may blur and lose quality as a result. OnSong can read JPEG files, but it may not display properly depending on size and complexity of the image. OnSong recommends a scan setting of 100 DPI greyscale if you intend to use scanned paper documents in OnSong. Since a chord chart may span more than one page, you may choose to scan as a PDF document.

Scanned Chord Charts

If the image is in a portrait orientation, or if the scan is landscape and the average color of all four corners has an average brightness greater than 93%, then the image is considered a chord chart.

Lyrics Projection Backgrounds

If the image is in the landscape orientation and not consider to be a paper scan, then the image is imported into your image media library. You can then use that background in the External Video Menu using the Background Image Picker toggle button.
