Swingify MusicXML

Manipulates <duration> and <divisions> elements of MuiscXML files so that any (quarter) beat starting with an eighth note is transformed to ternary (triplet) rhythms.

The result is targeted towards playback-oriented applications and might not be properly import into all MusicXML applications (specifically not notation-oriented ones).

Installation

(Pull requests for making swingify-musicxml properly installable welcome.)

Color flags

Colored notes are treated specially. If a beat starts with a red note (#FF0000), the beat is not swingified. Blue notes (#0000FF) are silenced. For how to override this, see the respective command line options.
