Ludus musicalis – Zwölf Modelle für Schulorchester (12 Models for School Orchestras) is a collection of compositions by Roman Haubenstock-Ramati that adopts "non-conventional" ways to encode the score. Sets of rules are provided and used by interpreters to decode various parameters. In this sense it contains aleatoric elements that might vary between performances. We developed a Python tool that allows for processing an image of a score in the format of Ludus musicalis (1-2 in particular) and generates a MIDI rendering as well a MusicXML transcription. With this tool we want to provide a way to familiarize with this type of notation, allowing to quickly generate possible renditions of these complex materials. Users can also draw new scores following Ludus musicalis rules, and have them performed, thus allowing a general public to interact with a form of notation not widely known.
